Sodium ethyl xanthate Sodium ethyl xanthate Sodium ethyl xanthate (SEX) is an organosulfur compound with the chemical formula CHCHOCSNa. It is a pale yellow powder, which is usually obtained as the dihydrate. Sodium ethyl xanthate is used in the mining industry as a flotation agent. A closely related potassium ethyl xanthate (KEX) is obtained as the anhydrous salt. As with most xanthates, sodium ethyl xanthate can be prepared by treating sodium ethoxide with carbon disulfide: Sodium ethyl xanthate is a pale yellow powder. It is relatively stable in water at high pH if not heated. It rapidly hydrolyses at pH <9 at 25
Ethyl cyanoacrylate and produce heat during polymerization. After curing, the resulting resin softens at temperatures above . The service temperature of the joint is . Its dielectric constant at 1 megahertz is 3.33. In the U.S., the Threshold Limit Value for ECA is 0.2 ppm. Heating causes depolymerization of the cured poly-ECA, producing gaseous products which are a strong irritant to the lungs and eyes. Ethyl cyanoacrylate Ethyl cyanoacrylate (ECA), a cyanoacrylate ester, is an ethyl ester of 2-cyano-2-propenoic acid. It is a colorless liquid with low viscosity and a faint sweet smell in pure form. It is the main component of
