Monga oleate ntchito ndi sodium?

Sodium oleate ndi sodium wochuluka mchere asidi oleic. Kupeza kiyi thupi katundu ndi mankhwala pawiri, ndi ntchito zake.

thupi katundu

ndi sodium oleate ali limatsogolera mfundo madigiri 220 Celsius. M'mikhalidwe wabwinobwino, ndi loyera kapena pang'ono chikasu ufa, amene ali mwangwiro sungunuka m'madzi ndi Mowa otentha. ndi sodium oleate osati kusungunuka efa ndi kafungo kabwino (ketone). pawiri Izi zili m'gulu la detergents ano ndi sopo.

ndi sodium oleate lili ndi zotsatira hydrophobic. Mutha kufotokozanso mwa mapangidwe zigawo kashiamu sopo zamchere zakuthupi.

mungachite kuti

Momwe ndi sodium oleate? Pawiri zochita kupanga ndilo maziko mapangidwe ake - ndi sodium wochuluka hydroxide. Mchere anapanga pa mankhwala anachita ya soda ndi oleic (organic) acid. Zimenezi ndi kusintha, choncho mgwirizano kosangalatsa kwa mapangidwe mankhwala anachita ntchito moyikirapo sulfuric asidi. Iyo imakoka mamolekyulu madzi, popeza hygroscopic.

Features katundu

ndi makhalidwe a oleate ndi sodium chiyani? The katundu pawiri ali m'magulu atatu:

• Collegiate. Akudalira pa chiwerengero cha mamolekyulu. Zikuphatikizapo kuthamanga kuchepa kapena kuwonjezeka kutentha, voliyumu.
• Zowonjezera. Iwo amayamba ndi mphamvu maselo, chimaonetsera Uwerenge katundu wa magulu a maatomu omwe ali mbali ya maselo a.
• Design. katundu zikuphatikizapo ochekenera mankhwala, dipole mphindi.

Sodium oleate ndi colloidal surfactant. Amakhala maatomu khumi mpweya kuti apange kupezeka khola la sakanikira dongosolo mtundu. Izi pawiri wa gulu kugwirizana ndi dongosolo mankhwala mankhwala ndi anionic surfactant. Nkhanizi ali kutsuka tingati agwiritsidwa kwa gulu chachinayi cha olemba PA Rehbinder. The kuyeretsa zotsatira ndi chifukwa kukhudzana pakati pa amadzimadzi njira ya mchere ndi pamalo a zolimba. Solubilization khalidwe la oleate ndi sodium ndi lalikulu zovuta yaitali detergency ake.

Micellization ndi mowiriza ndondomeko. Kwa iye, kuchuluka kwa kusintha wa mphamvu Gibbs ndi chizindikiro negative.

ntchito

Lomwe lili ndi sodium oleate? Gwiritsani pawiri monga emulsifier ndi lagona pa solubility zake zabwino mu madzi. Thiabendazole angagwiritsidwe ntchito yokonzekera emulsions khola la mtundu mafuta-madzi. Pambuyo kumayambiriro yankho chifukwa cha cations kashiamu pali imfa ya oleate insoluble, chimasintha chithunzi pa ndondomeko iwowo.

Chifukwa cha kukhalapo mu molekyulu ya organic mchere moiety amapezeka benzene kumamatira padziko. Nditadziŵana utoto mu emulsion Mwachitsanzo, Sudan III, sungunuka mu benzene onunkhira, angathe kuonedwa ndi kupezeka sing'anga gawo.

Mankhwalawa oleate ndi sodium yafupika kwambiri wettability khwatsi, zeta ake angathe. Santhulani dongosolo madzi a oleate ndi sodium. Mtengo wa mavuto padziko mchere kumabweretsa wongokhala kutsetsereka dera kwa ndende apamwamba. emulsifier ili pa ndende mkulu kumakhudza mwachindunji pa mtendere thovu.

Mu wosanjikiza pamwamba pa ndende mankhwala ndi wamkulu kuposa chithunzi ichi mu buku lake mu makumi a zikwi za nthawi. Maginito mankhwala ya amadzimadzi njira mchere amakhudza sorption ake katundu.

Lumikizanani ndi sodium wochuluka oleate mchere osiyanasiyana omwe nyese muzotsatira slurry mu kuchepetsa kutentha kwa wetting, kuchepetsa kachulukidwe kuwala wa njira.

Polongosola mwachidule, mwachitsanzo, kuti mwa ntchito zikuluzikulu za mchere organic tisaiwale oyamba a sopo ndi. Ndi katundu hydrophobic wa oleate ndi sodium anamuika otchuka pophika makampani zodzikongoletsera. Colloidal zimapangidwira, mmene pawiri ankanena anafotokoza thupi ndi mankhwala makhalidwe a zothetsera zochita kupanga ndi organic, ndi kulunjika ntchito zawo zothandiza.
