Methyl Montanate.—This compound was prepared by heating 200 c.c. absolute alcohol with 1 gram of montanic acid and 20 c.c. strong H2SO4 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

by crystallizing from ethyl alcohol. Thus obtained, methyl montanate melted at 67–67°5°. The melting-point was not changed by further crystallization.
Methyl montanate is a white soft solid, soluble in hot ethyl alcohol, and less soluble in methyl alcohol. It crystallizes from both solvents in glistening spangles.
Montanamide.—This compound was prepared in small quantity by heating 0°880 ammonia with ethyl montanate for three days in a sealed tube. It began to melt at 109°, and was completely melted at 111°. The sample was too small for analysis.
