Orthochlorbenzophenone. 



From orthochlorbenzoic anhydride, phosphorpentoxide, and benzol. 

 Crystallizes from ligroine in large rhombic prisms which deliquesce 

 slowly in the air, and melt at 40-41°. Readily soluble in alcohol, 

 ether, chloroform, and benzol, less easily in ligroine. It is best puri- 

 fied by distillation over a free flame and subsequent recrystallization 

 from ligroine. Analyses : —

Mctachlorbenzophenone. 



Crystallizes from alcohol or benzol in fine needles, which melt at 

 83°. Easily soluble in alcohol, ether, chloroform, benzol, and 

 ligroine. Analyses : —
