Uruganda Igiciro cyiza Acide Stearic CAS: 57-11-4

Acide Stearic, (urwego rwinganda) Acide Stearic nimwe mubintu byinshi binini byumunyururu muremure bigizwe namavuta hamwe namavuta.Itangwa mu binure byinyamanswa, amavuta nubwoko bumwebumwe bwamavuta yimboga kimwe na glyceride.Aya mavuta, nyuma ya hydrolysis, atanga aside stearic.
Acide Stearic ni aside irike iboneka cyane muri kamere kandi ifite imiterere rusange yimiti ya acide karubike.Hafi yubwoko bwose bwamavuta namavuta arimo aside stearic hamwe nibiri mumavuta yinyamanswa ugereranije.Kurugero, ibirimo amavuta bishobora kugera kuri 24% mugihe ibirimo amavuta yibimera ari bike ugereranije nagaciro kamavuta yicyayi ari 0.8% naho amavuta mumikindo akaba 6%.Nyamara, ibiri muri kakao birashobora kugera kuri 34%.

Hariho uburyo bubiri bwingenzi bwo gukora inganda za acide stearic, aribwo gucamo ibice no guhonyora.Ongeramo ibintu byangirika mumavuta ya hydrogène, hanyuma hydrolyze kugirango utange aside irike, hanyuma unyure mu koza amazi, kuyungurura, guhumanya kugirango ubone ibicuruzwa byarangiye hamwe na glycerol nkibibyara umusaruro.
Abenshi mu bakora uruganda bakoresha amavuta yinyamanswa kugirango babone umusaruro.Ubwoko bumwebumwe bwikoranabuhanga ribyara umusaruro bizavamo kutuzuza kwangiza aside irike itanga impumuro nziza mugihe cyo gutunganya plastike nubushyuhe bwinshi.Nubwo iyi mpumuro idafite uburozi ariko izagira ingaruka runaka kumikorere no kubidukikije.Ubwoko bwinshi butumizwa muri acide stearic ifata amavuta yimboga nkibikoresho fatizo, umusaruro uratera imbere;acide ya stearic yakozwe ni imikorere ihamye, amavuta meza yo kwisiga hamwe numunuko muke mubisabwa.
Acide Stearic ikoreshwa cyane cyane mukubyara stearates nka sodium stearate, magnesium stearate, calcium stearate, gurş stearate, aluminium stearate, cadmium stearate, stearate fer, na potassium stearate.Umunyu wa sodium cyangwa potasiyumu ya aside stearic ni igice cyisabune.Nubwo sodium stearate ifite ubushobozi buke bwo kwanduza kurusha sodium palmitate, ariko kuboneka kwayo bishobora kongera ubukana bwisabune.
Fata amavuta nkibikoresho fatizo, unyure muri acide sulfurike cyangwa uburyo bwotswa igitutu kugirango ubore.Amavuta acide yubusa yabanje gukoreshwa nuburyo bwumuvuduko wamazi kugirango ukureho aside palmitike na aside oleic kuri 30 ~ 40 and, hanyuma ushonga muri Ethanol, hakurikiraho kongeramo barium acetate cyangwa magnesium acetate igwa kuri stearate.Noneho ongera ushyiremo acide sulfurike kugirango ubone aside ya stearate yubusa, uyungurure uyifate, hanyuma wongere uhindure muri Ethanol kugirango ubone aside stearic nziza.
