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 butyrate Ethyl butyrate Ethyl butyrate, also known as ethyl butanoate, or butyric ether, is an ester with the chemical formula CHCHCHCOOCHCH. It is soluble in propylene glycol, paraffin oil, and kerosene. It has a fruity odor, similar to pineapple. It occurs naturally in many fruits. It is commonly used as artificial flavoring resembling orange juice or pineapple in alcoholic beverages (e.g. martinis, daiquiris etc.), as a solvent in perfumery products, and as a plasticizer for cellulose. In addition, ethyl butyrate is often also added to orange juice, as most associate its odor with that of fresh orange juice. Ethyl butyrate is
