Potassium ethyl xanthate Potassium ethyl xanthate Potassium ethyl xanthate (KEX) is an organosulfur compound with the chemical formula CHCHOCSK. It is a pale yellow powder that is used in the mining industry for the separation of ores. Unlike the related sodium ethyl xanthate, the potassium salt exists as an anhydrous salt. Xanthate salts are prepared by the action of alkoxides on carbon disulfide. The alkoxide is often generated in situ from potassium hydroxide: Potassium ethyl xanthate is a pale yellow powder that is stable at high pH but rapidly hydrolyses at pH <9 at 25 °C. Unlike the sodium derivative, potassium xanthate crystallizes
Ethyl methylphenylglycidate Ethyl methylphenylglycidate Ethyl methylphenylglycidate, commonly known as "strawberry aldehyde", is an organic compound used in the flavor industry in artificial fruit flavors, in particular strawberry. Because of its pleasant taste and aroma, ethyl methylphenylglycidate finds use in the fragrance industry, in artificial flavors, and in cosmetics. Its end applications include perfumes, soaps, beauty care products, detergents, pharmaceuticals, baked goods, candies, ice cream, and others. Ethyl methylphenylglycidate is classified as an ester and an epoxide; but, despite its common name, it is not an aldehyde. It is a colourless to pale-yellow liquid that is insoluble in water. Ethyl methylphenylglycidate is usually
