Versuchsvorschrift
71 g. of 3-chlorobenzyl alcohol, 60 cm3. of acetic acid and 1 g of p-toluene sulfonic acid are refluxed for 5 hours then the excess of acetic acid distilled off in vacuo. The residue is dissolved in 100 cm3. of 1,2-dichloro ethane and the solution washed with 10% sodium hydrogen carbonate solutin then with water and evaporated. The residue is distilled in vacuo. 85.5 g. of 3-chlorobenzyl acetate are obtained. Boiling point 105°-110° C./933.4 Pa, nD25 : 1.5185, yield 93%.
