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
2-Ethyl-1-butanol 2-Ethyl-1-butanol 2-Ethyl-1-butanol (IUPAC name: 2-ethylbutan-1-ol) is an organic chemical compound. It can be used to facilitate the separation of ethanol from water, which form an azeotrope that otherwise limits the maximum ethanol concentration. 2-Ethyl-1-butanol is manufactured industrially by the aldol condensation of acetaldehyde and butyraldehyde, followed by hydrogenation. It may also be prepared by the Guerbet reaction. The branching in 2-ethyl-1-butanol makes it harder to crystalize due to packing disruption, which results in a very low freezing point. Esters of 2-ethyl-1-butanol are similarly effected and it therefore finds application as a feedstock in the production of plasticizers and lubricants, where
