Umvelisi ofanelekileyo kwixabiso le-Stearic Acid ACID: 57-11-4

Inkcazo emfutshane:

I-Stearic Acid: (Ibanga lezamashishini) I-OctadeCanoic Acid, C18h36O, iveliswa yi-hydrolysis yeoyile kwaye isetyenziswa ikakhulu kwimveliso ye-Stearate
I-Stearic Acid-829 Stearic Acid, Stearic Acid yi-Acid eqinileyo ye-Acid, ezona zinto ziphambili ze-Stearic Acid (C186o2) kunye nePalmit Acid (C16H32O2).
Le mveliso imhlophe okanye imhlophe njengomgubo okanye i-crystalline hard, iprofayile yayo ine-microstrip lusters elungileyo yenaliti; Ine-odor encinci efana negrisi kwaye ayinantsingiselo. Le mveliso inyibilikisa kwi-chloroform okanye i-diethyl ethern, inyibilikisiwe e-Ethanol, phantse ingena emanzini. Inqaku le-freazing inqaku lendawo yokukhwaza (isiHlomelo ⅵ D) Imveliso ayiyi kuba ngaphantsi kwe-54 ℃. I-Iodine ixabise ixabiso le-iodine yale mveliso (isiHlomelo ⅶ h) ayingaphezulu kwe-4.

Izicelo ze-Stearic Acid

I-Stearic Acid, (Ibanga lezamashishini) I-Steric Acid yenye yee-acid ezinkulu ze-acids ezinamafutha ane-acid enamafutha aquka ioyile kunye ne-faks. Iboniswa kumanqatha ezilwanyana, ioyile kunye nezinye iintlobo zeoyile zemifuno njengefonti ye-Glycerides. Ezi oyile, emva kwe-hydrolysis, ivelise i-acid ye-stearic.
I-Stearic Acid yifadity acid esele ikho kwindalo kwaye inezinto zekhemikhali ngokubanzi ze-carboxylic acids. Phantse zonke iintlobo zamafutha kunye neoyile ziqulathe inani elithile le-stearic acid kunye nomxholo kumanqatha ezilwanyana xa silingana. Umzekelo, umxholo kwibhotolo unokufikelela kwi-24% ngelixa umxholo kwi-oyile yemifuno ihambelana nexabiso le-ITEA eyi-0.8% kunye neoyile kwi-6%. Nangona kunjalo, umxholo kwi-cocoa unokufikelela kwinqanaba lama-34%.

Zimbini iindlela eziphambili zokuveliswa kwemizi-mveliso ye-Stearic Acid, ezizezishini kunye nendlela yokunyanzelwa. Add decomposition agent to the hydrogenated oil, and then hydrolyze to give the crude fatty acid, further go through washing with water, distillation, bleaching to obtain the finished products with glycerol as the byproduct.
Uninzi lwabavelisi basekhaya basebenzise amanqatha ezilwanyana kwimveliso. Ezinye iintlobo zetekhnoloji yemveliso ziya kukhokelela ekungafezekini kokukhulu kwexabiso le-acid efake i-odor evuselelayo ngexesha lokusebenza kweplastiki kunye nobushushu obuphezulu. Nangona la ma i-odor ayinatyhefu kodwa aya kuba nefuthe elithile kwiimeko zokusebenza kunye nendalo. Eyona ndlela ingenisiweyo ye-Stearic Acid ithatha ioyile yemifuno njengezinto eziluhlaza, iinkqubo zemveliso zihambela phambili; I-stearic evelisiweyo ye-stearic ye-stearic yentsebenzo, ipropathi elungileyo ye-conbritt kunye nevumba elingaphantsi kwesicelo.
I-Stearic Acid isetyenziselwa ikakhulu ekuveliseni kwemveliso enjengeSodium Stearate, i-Ignesium Stearate, i-Calcium Stearate, i-Stearate, i-Aluminium Stearate, i-Cadmium Stearate, kunye ne-Steatium, kunye nePosium Steatium, kunye nePosium. I-sodium okanye i-potassium yetyuwa ye-stearic acid yinxalenye yesepha. Nangona i-sodium stearate inobuchule obungaphantsi kwe-sodium palmitate, kodwa ubukho bayo bongeza ubunzima besepha.
Thatha ibhotolo njengezixhobo ezibukhali, hamba nge-sulfuric acid okanye indlela yokucinezelwa. I-Acids enamafutha yasimahla yayiphantsi kwendlela yoxinzelelo lwamanzi yokususa i-palmic acid kunye ne-oleic acid, ilandelwe ngokongezwa kwe-ethanol, ilandelwe ngokongezwa kwe-bagium ye-Acetate okanye i-Agnesium ye-Acetate ePhakamisayo i-Steatite. Emva koko uqhubeke uyongeza i-dilute sulfuric acid ukufumana i-acid yasimahla ye-Acid, icebo lokucoca i-filter kwaye ulithathe, kwaye ulikhuphele i-ethanol ukufumana i-acid ecocekileyo.
