alcohol in glittering leaflets, melting at 77°. Readily soluble in 

 alcohol, ether, benzol, chloroform, and ligroine. Analyses : — 



0.2570 gr. substance gave 0..5619 gr. COj and 0.0962 gr. HjO. 

 0.1591 gr. gave 0.1133 gr. AgBr. 



Orthochlorhenzophenone. 



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 : — 



0.1401 gr. gave 0.3695 gr. COj and 0.0531 gr. H2O. 

 0.1143 gr. gave 0.0750 gr. AgCl. 



Metachlorhenzophenone. 



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

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

 ligroine. Analyses : — 



0.2158 gr. substance gave 0.5681 gr. COg and 0.0831 gr. HgO.
