Xanthates-tseem hu ua "xanthogenates"- yog cov hmoov daj daj uas muaj ntxhiab tsw ntxhiab; Lawv yog cov tshuaj lom, flammable, thiab nquag deliquescence nyob rau hauv lub xub ntiag ntawm noo noo. Chemically tsis ruaj khov, lawv tau nrawm nrawm nrawm thaum sib cuag nrog cov ntsev thiab yooj yim soluble hauv dej, acetone, thiab cawv. Cov tshuaj no paub tias ua rau lub siab, lub raum, thiab lub paj hlwb puas ntawm tib neeg thiab tsiaj txhu. Xanthates tau xub tsim los ntawm Keller hauv xyoo 1920. Lub invention ntawm xanthates muab ib tug zoo kawg li impetus rau kev nce qib ntawm cov ntxhia ua technologies; ntau hom xanthates ua cov khoom sau hauv cov txheej txheem floth flotation-ib daim ntawv thov uas suav rau lawv qhov ntim loj tshaj plaws ntawm kev siv. Tsis tas li ntawd, sodium ethyl xanthate thiab poov tshuaj ethyl xanthate pom muaj txiaj ntsig zoo li cov dej nag hauv hydrometallurgy thiab ua cov tshuaj intermediates. Hauv kev ua liaj ua teb, lawv tau ua haujlwm ua qoob loo desiccants; Thaum txau ntawm qhov tsim nyog theem ua ntej sau, lawv sai txo cov dej noo ntawm cov nplej husks, yog li yooj yim txheej txheem threshing.
Vim nws cov versatility, xanthan cov pos hniav yog dav siv nyob rau hauv kev lag luam khoom noj khoom haus raws li ib tug thickening tus neeg sawv cev, emulsion stabilizer, thiab tshem tawm tus neeg sawv cev -piv txwv li, nyob rau hauv kua ntses, dej haus, thiab ice cream. Nws kuj nquag ua haujlwm hauv cov roj av extraction, tshuaj pleev ib ce, thiab tshuaj lag luam los hloov kho cov khoom siv dej los yog tsim cov kev tswj hwm - tso tawm kev npaj. Tsis tas li ntawd, xanthan cov pos hniav ua haujlwm zoo li eco- cov ntaub ntawv tus phooj ywg thiab biomedical carrier, ua kom pom dav dav hauv kev tshawb fawb thiab kev siv engineering.
