It is soluble in hot glacial acetic acid, cliloroform, and benzene, but in- 

 soluble in ether and ligroin (40-60°). 



Calculated as C25H23O3N. Found.

Acetate of 3-4-'Uphenyl-.'}-fnnsiil-phi' nol . 



This product is obtained by boiling the _^^-keto-R-hexene derivative 

 with acetyl chloride on the water-bath for ten minutes. The mixture as- 

 sumes a deep red coloration. Nothing separates on cooling. When excess 

 of water is added, however, an amorphous mass separates which, upon 

 crystallization from hot ligroin (40-60°) or from aqueous alcohol, melts at 

 1415_2o It is soluble readily in cold benzene, ether, glacial acetic acid 

 and chloroform; sparingly soluble in hot benzene and aqueous alcoliol. 

 Calculated as C27H22O3. Found.

The acetate upon saponification with alcoholic potassium liydroxide 

 yields the phenol. The reaction requires only fifteen minutes heating 

 upon the water-bath to complete it. The product, which is obtained when 

 the resulting .solution is poured into dilute hydrochloric acid, is recrystal- 

 lized from a mixture of alcohol and ligroin (40-60°) and melts at 159-60°. 

 It is readily soluble in cold ether, benzene, chloroform and acetic acid, 

 and almost insoluble in hot ligroin. 



Calculated as C25H2(,02. Found.

This phenol reacts vigorously at the ordinary temperature with cold 

 concentrated nitric acid and yields nitro derivatives. These nitro bodies 

 will be investigated later.
