Qhov sib txawv tseem ceeb ntawm sodium stearate thiab sodium oleate yog sodium stearate yog sodium ntsev ntawm stearic acid, whereas sodium oleate yog sodium ntsev ntawm oleic acid.
Sodium stearate thiab sodium oleate yog sodium ntsev ntawm ob qhov sib txawv acidic compounds. Qhov no txhais tau hais tias cov tebchaw no muaj sodium ua ib qho cation thiab lub hauv paus ntawm cov kua qaub ua cov anions. Lawv muaj cov tshuaj lom neeg thiab lub cev sib txawv vim muaj cov qauv sib txawv.
Sodium Stearate yog dab tsi?
Sodium stearate yog cov organic compound uas muaj cov tshuaj formula C18H35NaO2Nws yog sodium ntsev ntawm stearic acid. Yog li, qhov sib xyaw no muaj cov sodium cation nyob rau hauv kev koom tes nrog lub hauv paus conjugate ntawm static acid (lub hauv paus conjugate yog stearate anion). Nws zoo nkaus li cov khoom dawb thaum npaj. Nws muaj me ntsis, siab-zoo li tsw thiab. Hauv nws daim ntawv dawb, sodium stearate yog ib qho tshuaj ntxuav tes. Tsis tas li ntawd, peb tuaj yeem pom qhov sib xyaw no hauv ntau hom deodorants, roj hmab, xim pleev xim, thiab inks. Qee zaum, sodium stearate muaj txiaj ntsig zoo li cov khoom noj ntxiv rau cov zaub mov flavouring.
Daim duab 01: Cov Qauv Tshuaj ntawm Sodium Stearate
Sodium stearate molecule muaj ob qho tib si hydrophilic thiab hydrophobic nyob rau hauv tib lub molecule. Qhov no yog ib tug yam ntxwv feature ntawm xab npum. Tsis tas li ntawd, nws muaj cov pab pawg carboxylate thiab cov saw hlau ntev hydrocarbon. Lub hydrophobic thiab hydrophilic qhov chaw nyob rau hauv no molecule induce tsim micelle thaum ntxiv rau dej. Lub taub hau hydrophilic tsim sab nraud ntawm micelle thiab hydrophobic tails tsim lub puab kheej kheej ntawm micelle. Sodium stearate muaj txiaj ntsig zoo hauv kev lag luam kws tshuaj raws li surfactant.
Sodium stearate ntau lawm yog ua los ntawm saponification ntawm cov roj thiab cov rog. Tus nqi ntawm sodium stearate tsim thaum lub sij hawm tsim cov qauv no nyob ntawm seb cov roj siv los ua cov reactants. E.g. siab yog rog.
Sodium Oleate yog dab tsi?
Sodium oleate yog cov organic compound uas muaj cov tshuaj formula C18H33NaO2 Cov tshuaj no tshwm sim raws li lub teeb tan khoom ntawm chav tsev kub. Nws muaj ib tug me ntsis siab-zoo li tsw. Sodium oleate yog sodium ntsev ntawm oleic acid. Yog li ntawd, cov molecule no muaj ib tug sodium cation thiab conjugate puag ntawm oleic acid; oleate anion. Cov tshuaj no tuaj yeem sib tov nrog dej maj mam.
Daim duab 02: Cov Qauv Tshuaj ntawm Sodium Oleate
Sodium oleate muaj ob daim ntawv cog lus ntawm nruab nrab ntawm nws cov saw hlau ntev. Yog li, qhov sib xyaw no qhia cis-trans geometry. Cov molecule kuj muaj ib pawg carboxylic acid, uas ua rau cov molecule hydrophilic thiab ntev carbon saw ua cov compound hydrophobic. Hauv cov tshuaj aqueous, qhov sib xyaw no ua rau me ntsis alkaline pH thaum tawg. Hauv kev lag luam khoom noj khoom haus, sodium oleate yog siv los ua tus stabilizer lossis ua cov thickener.
Qhov txawv ntawm Sodium Stearate thiab Sodium Oleate yog dab tsi?
Sodium stearate yog cov organic compound uas muaj cov tshuaj formula C18H35NaO2 thaum sodium oleate yog cov organic compound uas muaj cov tshuaj formula C18H33NaO2. Qhov sib txawv tseem ceeb ntawm sodium stearate thiab sodium oleate yog sodium stearate yog sodium ntsev ntawm stearic acid, whereas sodium oleate yog sodium ntsev ntawm oleic acid. Tsis tas li ntawd, sodium stearate yog cov khoom dawb thaum sodium oleate yog ib qho khoom me ntsis.
Hauv qab infographic tabulates qhov sib txawv ntawm sodium stearate thiab sodium oleate.
Summary – Sodium Stearate vs Sodium Oleate
Sodium stearate thiab sodium oleate yog sodium ntsev ntawm ob lub sib txawv acids. Qhov sib txawv tseem ceeb ntawm sodium stearate thiab sodium oleate yog sodium stearate yog sodium ntsev ntawm stearic acid, whereas sodium oleate yog sodium ntsev ntawm oleic acid.
