Abstract
A novel process for the preparation of benzyl alcohol by the hydrolysis of benzyl chloride, which operates with from 10 to 70 times the molar quantity of water at temperatures of from 80.degree. to 180.degree. C. and stops the reaction before complete conversion is reached, avoids both the addition of bases and water-soluble organic solvents and also the formation of sodium chloride.
Claims1
Process for the preparation of benzyl alcohol by the hydrolysis of benzyl chloride with water at elevated temperature, characterized in that the hydrolysis is performed at a molar ratio of benzyl chloride to water of from 1:10 to 1:70, at temperatures of from 80.degree. to 180.degree. C. and for a reaction time of 2 to 240 minutes until the conversion of benzyl chloride is from 35 to 99% and the yield is over 90% without addition of a base and without addition of a water-soluble organic solvent.
