Adipocelluloses and Cutocelluloses

from which, on cooling, a flocculent magma separated. This 

 was filtered, and washed with alcohol, and on treatment with hot 

 water melted to a greenish resinous mass (product A). 



The alcoholic filtrate on distillation gave a brownish-green 

 pasty residue (product B). 



These products, examined for nitrogen and mineral matter, 

 gave the following results : 



These numbers are explained by the presence of residues of 

 chlorophyll. 



The complex A yielded, on saponification with alcoholic 

 potash, a large proportion of ceryl alcohol (C2 7 H 35 OH), which 

 was proved to exist in the original substance, in great measure 

 in the uncombined state ; and at the same time a mixture of 

 oily ketones, the solutions of which were dichroic (orange 

 green). These ketonic bodies were found to be soluble in 

 sodium acetate solution, reacting in this solution with phenyl- 

 hydrazine (acetate), yielding crystalline precipitates. 



The residue from saponification of A, after removing these 

 compounds, was an inert resinous substance. 



By regulated fusion with sodium hydrate it was decomposed, 

 with formation of a mixture of acid bodies from which cerotic 

 acid (C 27 H 54 O 2 ) was isolated. The complex B contained (a) 

 carbohydrate derivatives soluble in water, and giving with boil- 

 ing hydrochloric acid a copious yield of furfural ; (d) ceryl 

 alcohol (about 10 p.ct.) and (c) the dichroic ketones (about 

 1 8 p.ct.) above described ; (d) acid bodies (50-60 p.ct.) of a 

 fatty character, giving soluble alkaline salts and insoluble salts 

 with the alkaline earth metals, insoluble also in alcohol.
