 a return condens; r. ()n3-h;,lf of the alcohol is distilled off and the residue 

 on cooling deposits wliite crystals, which, when they have been recrystol- 

 lized from a mixture of benzene and ligroin, melt at 221-3°. The sub- 

 stance is easily soluble in hot alcohol, cold etiier, acetic acid, and hot ben 

 zene, bv.t very sparingly soluble in bot ligroin (40-60^ j.

This body is prepared by boiling the _-i-keto-R-hexene derivative with 

 excess of eithc^r acetic anhydride or acetyl chloride for thirty mint.t( s. The 

 mixture assunn s a yellowisli-red tint, and yields a solid substance only 

 when it is poured into a large excess of water. The white amorphous mass 

 recrystallizes from hot ligroin (40-60°) in bunches of long needles, melting 

 at i)S°. It is soluble in cold glacial acetic acid, benzene, ether and alcohol, 

 but is sparingly soluble in ligroin.
