RiGG — Montan Wax. 283 



Another feature of interest is the sparing solubility of the sodium soap 

 in hot alcohol, for sodium cerotate dissolves without much difficulty. 



Barium montanate is fairly easily soluble in hot ammoniacal alcohol, 

 but calcium montanate is insoluble. 



, Montananilide. — This compound is new. It was prepared in a similar 

 manner to cerotanilide. The pure anilide, after repeated crystallization, 

 melted at 101-5°, and the melting-point was not changed by further 

 crystallization. 



Montananilide is soluble in those solvents mentioned for cerotanilide, 

 but the solubility has decreased somewhat. It crystallizes from alcohol 

 in groups of wavy needles. 



The kjeldahl method was used for estimating the nitrogen. 

 Calc. for C 34 H 61 O.N. Found. 



N = 2-80 2-40 



Montanone. — This ketone is new, and was prepared in a similar way 

 to cerotone: The ketone, after repeated crystallization, melted at 97-5°, 

 and the melting-point was not changed by further crystallization. A 

 50-per-cent. yield was obtained by this method of preparation.

Montanone Oxime. — This compound was prepared in a similar way to 

 cerotone oxime. The oxime, after repeated crystallization from ethyl 

 acetate, melted sharply at 82-5°, and further crystallization did not raise 

 the melting-point. Montanone oxime is a solid easily soluble in hot ethyl 

 acetate, motor spirit, and amyl alcohol, but somewhat sparingly soluble 

 in hot alcohol.

N = 1-74 1-74 



Ethyl Montanate. — This compound was prepared in a similar way to 

 ethyl cerotate. The melting-point of ethyl montanate, after repeated 

 crystallization from alcohol, was 67°, and this was unchanged by further 

 crystallization. Ethyl montanate is a white solid, easily soluble in hot 

 alcohol, from which it crystallizes in plates.

Methyl Montanate. — This compound was prepared by heating 200 c.c. 

 absolute alcohol with 1 gram of montanic acid and 20 c.c. strong H 2 S0 4 

 in sealed tubes maintained at a temperature of 110° for three days. 



The methyl montanate crystallized out in glistening spangles, and 

 was filtered off and purified, by removal of any free montanic acid, 

 by precipitation as the calcium salt. The filtrate from the insoluble 

 calcium salt deposited methyl montanate on cooling, and this was purified
