Umkhiqizi Price Omuhle Stearic Acid Chas: 57-11-4

I-Stearic acid, (ibanga lezimboni) i-stearc acid ingelinye lama-acid ama-acid amade ambalwa aqukethe amafutha namafutha. Kwethulwa emafutheni ezilwane, uwoyela kanye nezinhlobo ezithile zamafutha zemifino njengendlela ye-glycerides. Lawa mafutha, ngemuva kwe-hydrolysis, akhiqize i-acid ehlakaniphile.
I-Stearic acid iyi-acid enamafutha kabanzi ekhona ngokwemvelo futhi inezindawo zamakhemikhali ezijwayelekile zama-carboxylic acid. Cishe zonke izinhlobo zamafutha kanye namafutha aqukethe inani elithile le-stearic acid ngokuqukethwe kumafutha ezilwane aphezulu aphezulu. Isibonelo, okuqukethwe ebhotela kungafinyelela kuma-24% ngenkathi okuqukethwe kumafutha zemifino kuhlobene nenani letiye uwoyela we-0.8% kanye namafutha entendeni. Kodwa-ke, okuqukethwe ku-cocoa kungafinyelela phezulu ngama-34%.

Kunezindlela ezimbili ezinkulu zokukhiqizwa kwezimboni ze-Stearic Acid, okungukuthi i-Fractionation kanye nendlela yokucindezela. Ngeza i-ejenti yokubola emafutheni anamafutha, bese i-hydrolyze ukunikeza i-acid enamafutha e-crude, uqhubeke nokugeza ngamanzi, i-distillation, ukuxubha ukuthola imikhiqizo eqediwe nge-glycerol njenge-blycecerol njenge-blyceceruct.
Iningi labakhiqizi basekhaya basebenzisa amafutha ezilwane ukukhiqizwa. Ezinye izinhlobo zobuchwepheshe bokukhiqiza kuzoholela ekungathonini kwe-distillation ye-fatty acid ekhiqiza iphunga elivuselelayo ngesikhathi sokucubungula amapulasitiki. Yize le phunga lingabi bucayi kepha bazoba nomthelela othile ezimeni zokusebenza kanye nemvelo yemvelo. Uhlobo oluningi olungeniswa ezweni lwe-stearic acid luthatha uwoyela wemifino njengezinto zokwakha, izinqubo zokukhiqiza zithuthuke kakhulu; I-steartic acid ekhiqizwayo isebenza ezinzile, impahla ethokozisayo yokuthambisa kanye nephunga eliphansi kuhlelo lokusebenza.
I-Stearic acid isetshenziselwa ikakhulukazi ukukhiqizwa kokuqina okufana ne-sodium stearate, i-magnesium stearate, i-calcium stearate, i-aluminium stearate, i-aluminium stearate, i-aluminium stearate, i-iron stearate, ne-potassium stearate. Usawoti we-sodium noma we-potassium we-stearic acid yingxenye yensipho. Yize i-sodium stearate inekhono elincane lokuqothula kune-sodium plalmitate, kepha ukuba khona kwalo kungakhulisa ubunzima bensipho.
Thatha ibhotela njengento engavuthiwe, hamba nge-sulfuric acid noma indlela ecindezelwe yokubola. Ama-acid ama-fatty amahhala ayephansi kwendlela yokucindezela kwamanzi yokususa i-palmitic acid ne-oleic acid ngo-30 ~ 40 ℃, bese ekhishwa nge-ethanol, elandelwa ukwengeza kwe-barium acetate noma i-magnium acetate eqondile. Ngemuva kwalokho engeza i-dilute sulfuric acid ukuthola i-fulteate acid yamahhala, hlunga bese uyithatha, futhi uphinde ushaye kabusha i-ethanol ukuthola i-acid ehlanzekile ehlakaniphile.
