Acide Stearic, cyangwa aside octadecanoic, formula ya molekuline C18H36O2, ikorwa na hydrolysis yamavuta namavuta kandi ikoreshwa cyane mugukora stearates. Buri garama yashonga muri 21ml Ethanol, 5ml benzene, 2ml chloroform cyangwa 6ml ya karubone tetrachloride. Nibishashara byera bisobanutse neza cyangwa ibishashara byumuhondo byoroheje, birashobora gukwirakwizwa mubifu, hamwe numunuko wamavuta. Kugeza ubu, igice kinini cy’ibicuruzwa biva mu gihugu biva mu mahanga biva mu mahanga biva mu mahanga amavuta y’imikindo, hydrogène mu mavuta akomeye, hanyuma ikanagura hydrolysis kugirango ikore aside stearic.
Acide Stearic ikoreshwa cyane mumavuta yo kwisiga, plasitike ya pulasitike, ibikoresho byo kurekura ibiceri, stabilisateur, surfactants, umuvuduko wa rubber vulcanisation yihuta, imiti yica amazi, ibikoresho byogeza, amasabune yicyuma, ibikoresho bya minerval flotation, koroshya, imiti nindi miti kama. Acide Stearic irashobora kandi gukoreshwa nkigishishwa cyamavuta ya elegitoronike, amavuta yo kwisiga ya crayon, ibishashara byerekana ibishashara, hamwe na emulisiferi ya glycerol stearate. Acide Stearic nayo ikoreshwa cyane mugukora imiyoboro ya pulasitike ya PVC, amasahani, imyirondoro na firime, kandi ni stabilisateur yubushyuhe bwa PVC ifite amavuta meza hamwe numucyo mwiza hamwe nubushyuhe.
Mono- cyangwa polyol esters ya acide stearic irashobora gukoreshwa nka cosmetike, surfactants itari ionic, plasitike nibindi. Umunyu wacyo wa alkali ushonga mumazi kandi nikimwe mubice byingenzi bigize isabune, mugihe indi myunyu yicyuma irashobora gukoreshwa nkimiti yica amazi, amavuta, fungiside, ibyongeweho amarangi hamwe na stabilisateur ya PVC.
Uruhare rwa acide stearic mubikoresho bya polymeric bigaragazwa nubushobozi bwayo bwo kongera ubushyuhe bwumuriro. Ibikoresho bya polymer bikunda kwangirika no okiside mugihe cyo gutunganya ubushyuhe bwinshi, bigatuma imikorere igabanuka. Kwiyongera kwa acide stearic birashobora gutinda neza iyi nzira yo kwangirika no kugabanya gucamo iminyururu ya molekile, bityo bikongerera igihe cyo gukora cyibikoresho. Ibi ni ingenzi cyane mugukora ibicuruzwa birwanya ubushyuhe bwo hejuru nko kubika insinga hamwe nibigize imodoka.
Acide Stearic ifite amavuta meza yo gusiga amavuta. Mubikoresho bya polymer, acide stearic igabanya ubushyamirane hagati yiminyururu ya molekile, bigatuma ibikoresho bitemba byoroshye, bityo bikazamura imikorere yimikorere. Ibi ni ingirakamaro cyane mubikorwa byo kubyaza umusaruro nko guterwa inshinge, gukuramo no gutanga kalendari.
Acide Stearic yerekana plasitike yibikoresho bya polymeriki, byongera ubworoherane nubushobozi bwibikoresho. Ibi bituma ibikoresho byoroha kubumba muburyo butandukanye, harimo firime, tebes hamwe na profil. Ingaruka ya plastisike ya acide stearic ikoreshwa mugukora ibicuruzwa bipfunyika, imifuka ya pulasitike nibikoresho bya plastiki.
Ibikoresho bya polimerique bikunze gukurura amazi, bishobora gutesha agaciro imiterere yabyo kandi bigatera ruswa. Kwiyongera kwa acide stearic itezimbere amazi yibikoresho, bigatuma iguma ihagaze neza mubidukikije. Ibi nibyingenzi byingenzi mubice nkibicuruzwa byo hanze, ibikoresho byubwubatsi hamwe nibikoresho bya elegitoroniki.
Acide Stearic ifasha kugabanya ihinduka ryibara ryibikoresho bya polymeric muri UV hamwe nubushyuhe bwumuriro. Ibi nibyingenzi mugukora ibicuruzwa bitajegajega nkibicuruzwa byo hanze, ibyapa byimbere imbere nibikoresho byo hanze.
Acide Stearic ikora nka anti-adhesive and aid aid mubikoresho bya polymeric. Igabanya gufatana hagati ya molekile kandi ituma ibintu bigenda neza byoroshye, cyane cyane mugihe cyo gutera inshinge. Ibi bizamura umusaruro kandi bigabanya inenge mubicuruzwa.
Acide Stearic ikoreshwa nka anti-cake mugukora ifumbire mvaruganda kugirango habeho gukwirakwiza ifumbire mvaruganda. Ibi bifasha kuzamura ubwiza nuburinganire bwifumbire kandi bigatuma ibimera byakira intungamubiri zikwiye.
Acide Stearic ikoreshwa muburyo butandukanye bwinganda n’abaguzi.
