Sodium ethyl xanthate °C. It is the conjugate base of the unknown strong acid with p"K" of 1.6 and p"K" estimated as 12.4 for the conjugate base. Sodium ethyl xanthate easily adsorbs on the surface of solid sulfides. Xanthate are susceptible to hydrolysis and oxidation: These reactions require acidic conditions. Sodium ethyl xanthate can be identified through optical absorption peaks in the infrared (1179, 1160, 1115, 1085 cm) and ultraviolet (300 nm) ranges. There are at least six chemical detection methods: Sodium ethyl xanthate can also be quantified using gravimetry, by weighing the lead xanthate residue obtained after reacting SEX with 10% solution
Ethyl macadamiate Ethyl macadamiate Ethyl macadamiate is the ester of ethyl alcohol and the fatty acids derived from "Macadamia terifolia" seed oil (q.v.). Ethyl macadamiate is commonly used in cosmetic formulations. Ethyl macadamiate is the ethyl ester of the free fatty acids produced by the complete saponification of macadamia oil. The primary constituents of ethyl macadamiate are ethyl oleate and ethyl palmitoleate. Ethyl macadamiate is a clear, colorless liquid at room temperature, with a typical fatty ester odor. Ethyl macadamiate's melting (congealing) point is and its specific gravity is 0.88. Ethyl macadamiate spreads very aggressively, and has a light, nongreasy dry skinfeel
