Acide Palmitike (aside ya hexadecanoic muriIUPAC) ni aaside iriken'umunyururu wa karubone 16. Nibisanzweaside irikeiboneka mu nyamaswa, ibimera na mikorobe. Yayoimiti yimitini CH3(CH2)14COOH, hamwe na C: D igereranyo (umubare rusange wa atome ya karubone n'umubare wa karuboni-karubone inshuro ebyiri) ni 16: 0. Nibintu byingenzi bigizeamavuta y'imikindobivuye ku mbuto zaElaeis guineensis(imikindo y'amavuta), bigera kuri 44% by'amavuta yose. Inyama, foromaje, amavuta, nibindi bicuruzwa byamata nabyo birimo aside palmitike, bingana na 50-60% byamavuta yose.
Acide Palmitike yavumbuwe naEdmond Frémy(muri 1840) murisaponificationy'amavuta y'imikindo, inzira iracyakomeza inzira yambere yinganda zo kubyara aside.Triglyceride(ibinure) muriamavuta y'imikindonihydrolysedn'amazi yubushyuhe bwo hejuru kandi ibivanze nimu buryo butandukanye.
Acide Palmitike ikorwa nubwoko butandukanye bwibimera n’ibinyabuzima, mubisanzwe kurwego rwo hasi. Mu biribwa bisanzwe birahariamata,amavuta,foromaje, na bimweinyama, Nka Nkaamavuta ya kakao,amavuta ya elayo,amavuta ya soya, naamavuta yizuba.
Acide Palmitike ni aside irike yuzuye iboneka mubikoko n'ibimera. Nibintu nyamukuru bigize amavuta yintoki kandi biboneka no mu nyama, ibikomoka ku mata hamwe n’amavuta akomoka ku bimera. Acide Palmitike nayo iraboneka muburyo bwa powder kandi ifite uburyo bwinshi bwo gukoresha mubikorwa bitandukanye.
Ifu ya aside ya palmitike ikoreshwa cyane mu kwisiga no mu nganda zita ku muntu. Azwiho imiterere ya emollient, ifasha koroshya no koroshya uruhu. Bikunze gukoreshwa mugutegura amavuta, amavuta yo kwisiga, hamwe nubushuhe. Ifu ya aside ya Palmitike nayo ikoreshwa mubicuruzwa byita kumisatsi kugirango bifashe kumera no kugaburira umusatsi.
Acide Palmitike irashobora gukoreshwa murimurima:
Surfactant
Acide Palmitike ikoreshwa mu gutanga umusaruroamasabune,kwisiga, n'ingandakurekura abakozi. Izi porogaramu zikoresha sodium palmitate, ikunze kuboneka nasaponificationy'amavuta y'imikindo. Kugirango bigerweho, amavuta yintoki, yakozwe mubiti by'imikindo (ubwokoElaeis guineensis), bivurwa hamwehydroxide ya sodium(muburyo bwa soda ya caustic cyangwa lye), iterahydrolysisBya iestermatsinda, gutanga umusaruroglycerolna sodium palmitate.
Ibiryo
Kuberako idahenze kandi yongeraho imyenda kandi “umunwa”Ku biryo bitunganijwe (ibiryo byoroshye), aside palmitike n'umunyu wa sodiumi usanga bikoreshwa cyane mubiribwa. Sodium palmitate yemerewe nkinyongera karemano murikamaibicuruzwa.
Imiti
Ifu ya aside ya palmitike ikoreshwa nkibintu byangiza imiti itandukanye hamwe ninyongera. Ikoreshwa cyane nkamavuta mugukora ibinini na capsules. Ifu ya aside ya palmitike irashobora kandi gukoreshwa nkigikoresho cyo gufata imiti ikora neza, igafasha kuzamura umutekano hamwe na bioavailability.
Ubuhinzi
Ifu ya aside ya palmitike ikoreshwa nkibigize ibiryo byamatungo. Bikunze kongerwaho ibiryo byamatungo kugirango byongere imirire kandi biryoheye. Ifu ya aside ya palmitike irashobora kandi gukoreshwa nkigifuniko cy’ibicuruzwa byinjira mu buhinzi, bigafasha kunoza imikoreshereze yabyo no gukora neza.
Igisirikare
Aluminiumumunyuya aside ya palmitike naacide naphthenicbariibikoresho bya gellingikoreshwa hamwe na peteroli yimiti ihindagurika mugiheIntambara ya kabiri y'isi yosekubyaranapalm. Ijambo "napalm" rikomoka ku magambo acide naphthenic na aside palmitike.
Muri rusange, ifu ya aside ya palmitike ifite uburyo bwinshi bwo gukoresha mu nganda zitandukanye, bigatuma iba ibintu byinshi kandi bifite agaciro. Ibiranga emollient, ituze kandi bihindagurika bituma ihitamo gukundwa mubashinzwe gukora no gukora ibicuruzwa bashaka kuzamura ibicuruzwa nibikorwa.
