Abstract

PURPOSE: To obtain the high purity title compound, useful as a synthetic intermediate of, e.g. agricultural chemicals, in high yield, by reacting 4-alkylphenol with Cl2 in a solvent in the presence of an amine as a catalyst, thereby chlorinating the alkylphenol at the nucleus.
CONSTITUTION: 4-Alkylphenol of the formula (R=lower alkyl) and Cl2 are introduced simultaneously into a reaction vessel containing a specific amount of a slvent, e.g. tetrachlorethylene, and a specific amount of a catalyst of amines. The nucleic chlorination is accomplished at 0W90°C for 1W20hr. After washing the reaction products with n aqueous solution of e.g. Na2SO3, the solvent is removed to give the objective compound. The amines used are e.g. dicyclohexylamine, n-propylamine, aniline, benzylamine, morpholine etc. The amount of these amines is 0.0001W0.003mol to 1mol of 4-alkylphenol. The amount of the solvent used is 1-several times the amount of 4-alkylphenol.
