Propan-1-ol and propan-2-ol are both alcohols that share the same general chemical formula (C3H8O), so what is the difference between them exactly? It all comes down to their atomic arrangement and how the hydroxyl group is positioned. In a nutshell, the difference between propan-1-ol and propan-2-ol is the position of their respective hydroxyl (-OH) groups. Propan-1-ol has an –OH group attached to its terminal carbon atom while propan-2-ol has an –OH group attached to its middle carbon atom. This small difference in chemical structure is enough to make a noticeable impact in the way these two alcohols behave, in the way they can be used and in the way they are categorised. What Are Alcohols?What is Propanol?Propan-1-olPropertiesChemical StructurePropan-2-olProperties Chemical StructureSimilarities What Are Alcohols? Alcohols are chemical compounds that contain carbon and hydrogen atoms as well as a hydroxyl group (-OH). There are many different types of alcoholic compounds and each one can be put into one of three categories: primary, secondary or tertiary. The category of an alcohol is determined by the position of the hydroxyl group. For example, if the hydroxyl group is attached to a primary or terminal carbon atom, one that is at either end of the carbon chain, then it is a primary alcohol. If the hydroxyl group is attached to any other carbon atom, not at the end of the chain, then it is classified as either secondary or tertiary. The name of an alcohol is derived from the number of carbon and hydrogen atoms as well as the alkane backbone that the hydroxyl group attaches to. For example, an –OH group attaches to an: Ethane (C2H6) backbone to form ethanol (C2H6O) ethyl alcohol Methane (CH4) backbone to form methanol (CH3OH) methyl alcohol Butane (C4H10) backbone to form butanol (C4H10O) butyl alcohol Propane (C3H8) backbone to form propanol (C3H8O) propyl alcohol These four compounds are the simplest alcohols and also the most common, but their different structures give them each different properties. What is Propanol? The molecular structure of propanol is comprised of a 3-carbon backbone that 8 hydrogen atoms, including a hydroxyl group, are attached to. However, the propanol molecule can occur in 2 different forms. This means there are 2 isomers of propanol, and they can be identified by the position of the hydroxyl group on the carbon backbone: Propan-1-ol has its –OH group attached to the terminal carbon atom of the molecule Propan-2-ol has its –OH group attached to the middle carbon atom of the molecule While they do have certain similarities, the structural nuances between the two molecules cause differences in the properties of propan-1-ol and propan-2-ol. Also known as 1-propanol, this compound is a primary alcohol that is most commonly used as a solvent in the pharmaceutical industry. Although it has the general formula C3H8O, its specific molecular structure can also be expressed as CH3CH2CH2OH to show that the hydroxyl group is attached to a terminal carbon atom. This is what categorises propan-1-ol as a primary alcohol. Properties Physically, propan-1-ol appears as a colourless liquid at room temperature and it is characterised by a fruity flavour and mildly alcoholic smell. Chemically, it is a primary alcohol and an isomer of propan-2-ol. Other notable properties include: Melting Point: -126°C Boiling Point: Molar Mass: g/mol High rate of esterification Difficult to dehydrate Chemical Structure Structurally, propan-1-ol has 3 carbon atoms bonded to each other. This forms the backbone of the molecule. Its structure is only comprised of single bonds, making it a saturated compound. Because the hydroxyl group is connected to a terminal carbon atom, a carbon atom positioned at the end of the carbon chain, propan-1-ol is a primary alcohol. As a primary alcohol, it forms aldehydes when it undergoes oxidation and it is more acidic than other alcohol categories. Propan-2-ol Most commonly known as isopropyl alcohol (IPA) or isopropanol, propan-2-ol is a secondary alcohol that has a wide range of applications across many different industries. Like propan-1-ol, its general formula is C3H8O but it can also be structurally expressed as CH3CH(OH)CH3 to show that the hydroxyl group is attached to a middle carbon atom instead of a terminal one. This is what makes propan-2-ol a secondary alcohol. Properties Propan-2-ol is not dissimilar to propan-1-ol in that it appears as a colourless liquid at room temperature. It can be physically distinguished from propan-1-ol by its comparatively pleasant odour and its bitter, instead of fruity taste. Chemically, propan-2-ol is a secondary alcohol and a structural isomer of propan-1-ol. Other notable properties include: Melting Point: -89°C Boiling Point: Molar Mass: g/mol Low rate of esterification Easier to dehydrate than propan-1-ol Chemical Structure Structurally, propan-2-ol also has a backbone of 3 carbon atoms bonded together. Like propan-1-ol, this is also a saturated compounded because it only has single bonds. The only difference in structure between these two isomers is the positioning of the hydroxyl group. Because the –OH group is attached to a middle carbon atom, propan-2-ol is classed as a secondary alcohol. As a secondary alcohol, propan-2-ol is generally more reactive, more stable and less acidic than propan-1-ol. It also forms ketones instead of aldehydes when it undergoes oxidation. Similarities While there are many differences between these two compounds, they also share several similarities: They are both alcoholic compounds They both have the same formula They both contain three carbon atoms They both contain eight hydrogen atoms They both contain a hydroxyl group They are both colourless liquids They have the same molar mass They can both be used as solvents ReAgent are leading manufacturers of propan-2-ol and are internationally recognised for our uncompromising quality.

N-propanol (also known as 1-propanol, n-propanol alcohol, propan-1-ol, propyl alcohol) is a primary alcohol in which the OH entity is bonded to a primary carbon atom. N-propanol (CH3CH2CH2OH) is one of two isomers of propanol (C3H8O); the other is 2-propanol ((CH3)2CHOH). It is a clear, colourless transparent liquid that has a typical sharp musty odour that is comparable with the smell of rubbing alcohol. Miscible in water and freely miscible with all common solvents such as glycols, ketones, alcohols, aldehydes, ethers and aliphatic hydrocarbons, 1-propanol is primarily used as a solvent in the manufacturing of pharmaceuticals, cosmetics, coatings and as a chemical intermediate. 1-propanol technical properties Chemical and physical properties of n-propanol: Molecular Formula: CH3CH2CH2OH / n-PrOH Synonyms: 1-propanol, n-propanol alcohol, propan-1-ol, propyl alcohol, n-PrOH, 1-hydroxypropane, propionic alcohol Cas Number: 71-23-8 Molecular Mass: g/mol-1 Exact Mass: g/mol Flashpoint: 77 °F / 22 °C Boiling Point: 207 °F (at 760 mm Hg) / °C Melting Point: -195 °F / -126 °C Vapour Pressure: kPa (at 20 °C) Water Solubility: miscible Density: g/mL Log P: N-propanol forms naturally during fermentation processes. The human gastrointestinal microbiota can also produce small amounts. How is N-Propanol produced? Normal propanol is manufactured by a catalytic hydrogenation of propionaldehyde. The propionaldehyde is itself produced via the oxo process, by hydroformylation of ethylene using carbon monoxide and hydrogen in the presence of a catalyst such as cobalt octacarbonyl or a rhodium complex. Hydrogenation is the process of adding pairs of hydrogen atoms to unsaturated compounds, with the aim of saturating these compounds. H2C=CH2 + CO + H2 → CH3CH2CH=O CH3CH2CH=O + H2 → CH3CH2CH2OH Handling, Storage & Distribution Hazards & Toxicity N-propanol has an NFPA health rating of 1, causing irritation to your eyes, nose, and throat. High exposure can cause burning, nausea, headaches, and dizziness. Vapours of n-propanol are heavier than air and can also irritate and burn. It has a flammability rating of 3, demonstrating that it can be easily ignited under most ambient temperatures. An instability rating of 0 indicates that n-propanol will remain stable, even when under fire conditions. N-propanol sits in the alcohol and polyol reactive groups. It reacts with alkali metal, nitrides, oxoacids and carboxylic acids. It is not reactive with strong oxidising agents. It reacts the same way as primary alcohols. It can be converted to alkyl halides (red phosphorus, iodine), acetic acid to give propyl acetate and chromic acids to give propionic acid. Storage & Distribution N-propanol alcohol is typically bulk stored within a petrochemical storage facility for regulation. Storage is normally in a cool, dry and well ventilated facility away from oxidising agents. It should be kept out of direct sunlight, heat, and open flames. It can be stored in drummed containers such as iso tanks made of stainless steel, aluminium or carbon steel. N-propanol alcohol is exported in bulk vessels or tank trucks. For transportation purposes, it is classed as a flammable liquid with a fire hazard rating of 2. A full bulk chemical distributor would export the solvent throughout regions such as the UK, Europe, Africa, and America. It belongs to packing group 2. Safety & Procedures Personal protective equipment should be worn to prevent contact with the skin, eyes, nose and mouth, including respirators, safety glasses/goggles, gloves and contact lenses. If contact is made with the skin, immediately wash the contaminated area and clothing should be removed. Immediately wash the eyes with large amounts of water and seek medical attention immediately. Seek fresh air if large amounts of n-propanol have been inhaled. Learn more about the different first aid procedures here. What is 1-propanol used for?
