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 Gasoline Corp. v. United States laws, and accordingly was illegal when its effect was to "regiment" an entire industry. Ethyl owned several patents on tetra-ethyl lead, an anti-knock fuel additive, and on its utilization: two patents on the chemical itself, a patent on a motor fuel—gasoline containing tetra-ethyl lead, and a patent on a method of using the fuel in an automobile engine. Ethyl established an elaborate licensing program under its several patents: Ethyl sold the fuel additive, and licensed purchasers to use it to practice the other patents. The licensing program fixed prices for the motor fuel and strictly limited the types of customer
