Sodium Stearate don Anionic Surfactant da Sabulu

Sodium stearate shine gishirin sodium na stearic acid, wanda kuma aka sani da sodium octadecate, wanda aka saba amfani da shi anionic surfactant kuma babban bangaren sabulu.Motsin hydrocarbyl a cikin ƙwayar sodium stearate ƙungiya ce ta hydrophobic, kuma ƙwayar carboxyl ƙungiya ce ta hydrophilic.A cikin ruwan sabulu, sodium stearate yana cikin micelles.Micelles suna da siffar zobe kuma sun ƙunshi kwayoyin halitta da yawa.Ƙungiyoyin hydrophobic suna cikin ciki kuma an haɗa su da juna ta hanyar dakarun van der Waals, kuma ƙungiyoyin hydrophilic suna waje da rarraba a saman micelles.Miceles suna tarwatse a cikin ruwa, kuma lokacin da aka gamu da tabon mai da ba za a iya narkewa da ruwa ba, ana iya tarwatsa mai cikin ɗigon mai mai kyau.Ƙungiyar hydrophobic na sodium stearate ta narke cikin mai, yayin da ƙungiyar hydrophilic An dakatar da shi a cikin ruwa don lalata.A cikin ruwa mai wuya, ions stearate suna haɗuwa tare da alli da magnesium ions don samar da calcium da magnesium salts na ruwa wanda ba zai iya narkewa ba, yana rage ƙazanta.Baya ga sodium stearate, sabulu kuma ya ƙunshi sodium palmitate CH3(CH2)14COONa da sodium salts na sauran fatty acid (C12-C20).
