Stearic acid yog ib qib siab cov roj av roj acid, purely ua los ntawm cov ntsiav tshuaj dawb nrog gloss. Tus txheeb ze ceev yog 0. 9408 (20 degree), 20} Cov qib, thiab ntsuas kom muaj zog yog 1.4299 (80 degree).
Nws cov khoom lag luam yog xim dawb lossis me ntsis daj granular, thiab palmites acid, thiab muaj me me ntawm oleic acid, nrog ib tug me ntsis butter-zoo li ntxhiab tsw. Soluble me ntsis hauv dej txias, yooj yim soluble hauv benzene, Toluene, carbon tetrachloride, carbon atetate, thiab lwm yam hauv ethanol thiab kuj soluble hauv ethanol thiab acetone. Cov khoom lag luam tau muab faib ua cov khoom lag luam ua ntej (lossis hom 200, cov khoom lag luam qub) thiab cov khoom lag luam thib ob (lossis hom 800, uas tau raug nias ib zaug lossis tsis). Cov khoom lag luam tseem ceeb thiab theem nrab yog cov khib nyiab dawb, thaum theem peb cov khoom lag luam yog lub teeb daj waxy cov khib nyiab. Stearic acid yog tsis tshua pom pom ib leeg hauv qhov thiab feem ntau muaj nyob rau hauv daim ntawv ntawm cov roj thiab cov rog thiab cov nroj tsuag, uas yog qhov muaj ntau tshaj plaws. Stearic acid yog ib organic acid uas tuaj yeem ua haujlwm nrog alkali los tsim cov sodium stearate thiab yog xab npum.
Stearic acid yog siv dav. Hauv kev lag luam tshuaj pleev ib ce, nws yog cov khoom siv tsis tseem ceeb rau kev tsim cov khoom lag luam emolulified. Nws yog siv los npaj sauce qab zib, txias qab zib, lub hauv paus cream, shating cream, plaub hau saib xyuas cov tshuaj pleev plaub hau. Hauv cov roj av kev lag luam, nws yog vulcanizing nquag tus neeg sawv cev rau tej yam ntxwv cov kua nplaum, cov kua nplaum hluavtaws thiab cov kua yas, thiab tseem siv los ua cov mos muag. Nws yog siv los ua cov yas yas, stabilizer thiab roj nplua nyeem hauv cov ntaub lag luam plastics. Nws yog siv los ua cov xov paj roj thiab ib qho muag muag rau cov tshuaj tiv thaiv zoo hauv kev lag luam textile. Nws kuj yog siv los ua cov tshuaj tawm ua ke, cov neeg sawv cev polishing, pleev xim rau cov neeg sawv cev tawv nqaij, cov ntaub ntawv ua kom huv si, cov khoom siv lim dej textile. Nws yog qhov hnyav rau cov roj-soluble xim. Nws tseem yog cov khoom siv raw rau kev tsim cov rog ntau dua li cov methyl stearate, calcium stearate, potassium stearate, txhuas stearate, thiab lwm yam.
Stearic acid yog tsim los ntawm hydrogenated cottonseed roj, cov roj av, benzene, Benzene, naphton rog, nias (lossis tsis txhob nias), pickling thiab decolorization.
