The acetate is boiled upon a water-bath witli alcoliolic potassium liy- 

 droxide for fifteen minutes. The mixture resulting is poured into excess of 

 dilute hydrochloric acid, and a white mass is obtained. The amorphous 

 phenol is recrystallized from hot alcohol. It forms white needles, which 

 melt at 155°. It is readily soluble in cold chloroform, benzene and ether, 

 but sparingly soluble in hot ligroin (-10-60°). 

 Calculated as C27H240. Found.

The 3-4-diphenyl-5-anisyl-4-oxy- ^ o-keto-R-hexene is prepared by 

 the condensation of one molecule (6 gr.) of benzoin, either with one mole- 

 cule (5 gr. ) anisylidenacetone, or with one molecule each of anisaldehyde 

 (3.9 gr.) and of pure acetone (1.7 gr. ) under exactly the same conditions 

 whicli were used in the preparation of 3-J:-dipheuyl-5-cumyl-l-oxy-/\2- 

 keto-R-hexene. The substance crystallizes in bunches of needles, either 

 from hot glacial acetic acid, or absolute alcohol, and melts at 233.5°. 

 Ho.wever the amount of alcohol required is large — for each gram, 70cc. of 

 liot absolute alcohol are required. It is soluble in hot benzene and chloro- 

 form, but insoluble in ether and ligroin (40-60^). With cold concentrated 

 sulphuric acid, a deep red coloration is produced. 



Calculated as C25H22O3. Found.

 For the preparation of the oxim, a method, analogous to that described 

 in the preparation of the oxim of 3-4-diplienyl-5-cuniyl-4-oxy-^^2~'^6to- 

 R-hexene, is used. After recrystallization from liot alcohol, it melts at 196°.
