Sodium Stearate ya Anionic Surfactant ndi Sopo

Sodium stearate ndi mchere wa sodium wa stearic acid, womwe umatchedwanso sodium octadecate, womwe umagwiritsidwa ntchito kwambiri ndi anionic surfactant komanso chigawo chachikulu cha sopo.Gulu la hydrocarbyl mu molekyulu ya sodium stearate ndi gulu la hydrophobic, ndipo carboxyl moiety ndi gulu la hydrophilic.M'madzi a sopo, sodium stearate ilipo mu micelles.Micelles ndi yozungulira ndipo imakhala ndi mamolekyu ambiri.Magulu a hydrophobic ali mkati ndipo amaphatikizidwa wina ndi mzake ndi mphamvu za van der Waals, ndipo magulu a hydrophilic ali kunja ndikugawidwa pamwamba pa micelles.Ma micelles amamwazikana m'madzi, ndipo akakumana ndi madontho osasungunuka amafuta, mafutawo amatha kumwazikana kukhala madontho abwino amafuta.Gulu la hydrophobic la sodium stearate limasungunuka mu mafuta, pamene gulu la hydrophilic Limayimitsidwa m'madzi kuti liwonongeke.M'madzi olimba, ma ion a stearate amaphatikizana ndi ayoni a calcium ndi magnesium kuti apange calcium yosasungunuka m'madzi ndi mchere wa magnesium, kuchepetsa kutsekemera.Kuphatikiza pa sodium stearate, sopo imakhalanso ndi sodium palmitate CH3(CH2)14COONa ndi mchere wa sodium wamafuta ena acid (C12-C20).
