446 PROCEEDINGS OP THE AMERICAN ACADEMY. 



the precipitate of sodic chloride, and the filtrate on cooling deposited 

 well formed crystals of the new substance, which was purified by 

 recrystallization from alcohol until it showed the constant melting 

 point 122°-123°, when it was dried, and analyzed with the following 

 result : — 



0.1866 gram of the substance gave by the method of Carius 0.1075 

 gram of argentic chloride. 



Calculated for 

 C6Cl2(OC2H5)„(OC2H5).>(OCOOC2H5)2. Found. 



Chlorine 14.18 14.24 



The substance crystallizes in white flat prisms, terminated usually 

 by a single plane at a very sharp angle, which is occasionally modified 

 by a sei-oud smaller plane. It melts at 122°-123°, and is readily 

 soluble in alcoliol, chloroform, benzol, or acetone ; soluble in glacial 

 acetic acid, or carbonic disulphide ; slightly soluble in ether; insoluble 

 in water. The best solvent for it is alcohol. In view of the results 

 of tlie saponification of the corresponding benzoyl compound the 

 decomposition of this substance with sulphuric acid of specific gravity 

 1.44 promises to be interesting. Unfortunately, it was prepared just 

 before the vacation, so that this work must be postponed until the 

 next college year. 



Action of Potassic Phenylate on Dichlordiphenoxyqidnone. — 

 Tetraphenoxyquinone, Q>^^{OC^^ ^O^- 



By treating 10 grams of pure dichlordiphenoxyquinone with a little 

 more than two equivalents of potassic phenylate, made by dissolving 4 

 grams of potassic hydrate and 12 grams of phenol in 150 c.c. of water, 

 tetray)henoxyquinone was formed. In order to complete the reaction 

 it was necessary to boil the dichlordiphenoxyquinone with the potas- 

 sic phenylate for twenty to thirty minutes. The product formed was 

 then filtered ofp. and after washing thoroughly with water and alcohol 

 was fturifiFd by crystallization from benzol until it gave the constant 

 melting p'«int of 229°-230°. After drying at 100°, the substance 

 gave the following results on analysis : — 



I. 0.2198 gram of the substance gave on combustion 0.6122 gram 

 of carbonic dioxide and 0.0865 gram of water. 



Calculated for Cp,(0C6H5)402. Found.
