Write a mechanism for the reaction of p-toluidine with acetic anhydride

Benzyl alcohol, also called phenylmethanol or phenylcarbinol, is a clear, colorless liquid with a mild pleasant aromatic odor; melting at 15 C and Boiling at C. It is a primary alcohol with arene group. It is partially soluble in water and readily soluble in alcohol and ether.

Benzyl alcohol is prepared by the hydrolysis of benzyl chloride in the presence of soda ash. Benzyl alcohol has properties of strong polarity and limited water solubility. It features also good solvency, low toxicity and low vapor pressure. It reacts with acids acetic, benzoic, and sebacic acids, and etc to form numerous esters, salts and other compounds, thus is used widely as a valued intermediate in industrial field as well as in making soap, perfume, and flavors.

This compound is used as a dyeing assistant for filament nylons. Its applications include many pharmaceutical preparations and bacteriostatic compounds.

It was used for antipruritic activity to relieve itching.

In carbinol nomenclature system, the term of carbinol is methanol itself and other groups are considered to have replaced one of the methanol hydrogen atoms to describe larger alcohols as derivatives of carbinol.

This nomenclature system is particularly useful when the groups attached to the methanol carbon are large, aromatic, and cyclo groups.

Benzyl alcohol is called phenylcarbinol or benzenecarbinol while benzyl carbinol is phenylethyl alcohol. Alcohols are widely used as solvents, fuels and chemical raw materials.

Generally, hydroxyl group compounds are polar, which trends to promote solubility in water. But the carbon chain resist to solubility in water. Short chain alcohols methanol, ethanol, and propanol in which the hydroxyl group predominates are miscible in water.

Butanol is moderately soluble because of the balance between the two opposing solubility trends. Higher alcohols are practically insoluble in water because of the hydrocarbon chain's trend is stronger.

Alcohols are "protic" solvents. Protic refers to a hydrogen atom attached to an electronegative atom, oxygen. Water-soluble alcohols, low-molecular weight products, are solvents for the manufacture of coatings, dyes and inks, plastics, flavorings, personal-care products, pharmaceuticals, and cleaners.

Primary and secondary alcohols can be oxidized to aldehydes and ketones respectively. Carboxylic acids are obtained from oxidation of aldehydes.

Oxidation in organic chemistry can be considered to be the loss of hydrogen or gain of oxygen and reduction to gain hydrogen or loss of oxygen.


Tertiary alcohols do not react to give oxidation products as they have no H attached to the alcohol carbon. Alcohols undergoes important reactions called nucleophilic substitution in which an electron donor replaces a leaving group, generally conjugate bases of strong acids, as a covalent substitute of some atom.

One of important reaction of alcohol is condensation. Ethers are formed by the condensation of two alcohols by heating with sulfuric acid; the reaction is one of dehydration. Almost infinite esters are formed through condensation reaction called esterification between carboxylic acid and alcohol, which produces water.

Alcohols are important solvents and chemical raw materials. Alcohols are intermediates for the production of target compounds, such as pharmaceuticals, veterinary medicines, plasticizers, surfactants, lubricants, ore floatation agents, pesticides, hydraulic fluids, and detergents.

Benzyl alcohol, an aromatic primary alcohol, is a clear, oily liquid with a mild, pleasant odor; melting point at C; boiling point at C; specific gravity 1. It is soluble in water and readily soluble in alcohol and ether. The benzene ring can be a ring-substituted with alkyl groups.Search among more than user manuals and view them online regardbouddhiste.com Question: Write a mechanism for the reaction of p-toluidine with acetic anhydride.
