B. Second Method of Preparation.—Para-methyl-w-chloracetyl 
benzene (CH;0,H,COCH.Cl) was prepared by the method of 
Collet,’ by adding in small quantities, with frequent shaking, a 
mixture of chloracetyl chloride and toluene (dried over sodium) to 
- aluminium chloride covered with a layer of carbon disulphide in a 
flask. The mixture was finally kept at a temperature of about 40° C. 
until hydrochloric acid ceased to be evolved. It was poured into 
ice-cold water, acidified, separated, washed with a little water, dried 
over calcium chloride and fractionated. 
The portion boiling between 260-265° C. solidifies on cooling, 
and consists of nearly pure p.-methyl-chloracetyl benzene.

is got by 1 hour’s heating of an intimate mixture of 16°8 grams 
p--methyl-a-chloracetophenone, prepared by the method of Collet 
described above, and 18°5 gs. potassium phtalimide at 160°. A 
solid brown mass results on cooling, which, boiled out with water 
and alcohol, was recrystallized from glacial acetic acid and gave 
octahedra-like crystals, melting at 175°-176°. The yield of 20 gs. 
is 72 per cent. of the theoretical.

The body is scarcely soluble in water, slightly in alcohol and 
ether, easily in hot glacial acetic acid.
