Hexanoic acid raws li ib tug neeg sawv cev ntawm lub roj nyeem fatty acids
Lub ntuj yam muaj feem ntau noo li qub qauv acid. Lawv lub zog yog nyob ntawm seb molecular ceeb thawj. Cov acids yuav tsim eutectic mixtures - lub melting alloys nrog rau qhov kub thiab txias, ua tsis yooj yim sua lawv sib cais mus rau hauv ib tug neeg lub Cheebtsam, txawm nyob rau hauv tus txheej txheem ntawm re-crystallization.
Nws yuav tsum tau muab sau tseg tias cov acids yog soluble nyob rau hauv yuav luag tag nrho cov organic solvents xws li diethyl ether, acetone los yog chloroform. Tsis tas li ntawd, lawv yog sufficiently resistant mus rau ntau yam reagents (oxidants, halogens los yog lwm yam sib txuas). Lub ntsiab cov neeg sawv cev ntawm no pab pawg neeg ntawm cov tshuaj tebchaw - yog butyric, caprylic, lauric, myristic, palmitic, hexanoic acid, thiab lwm yam Tus qauv ntawm feem ntau acids, uas yog muaj nyob rau hauv tej yam ntuj tso rog, twb tsis siv ib qho feature -. Lawv muaj ib tug txawm tooj ntawm cov pa roj carbon atoms.
Caproic acid yog ib tug muaj koob sawv cev ntawm nyeem fatty acids. Qhov no oily kua yog tsis muaj kob, uas yog yus muaj los ntawm ib tug ntse tsis kaj siab tsw. Nws yog ib feem ntawm lub txiv maj phaub, xibtes, thiab butter.
Caproic acid yuav tas los ntawm ib tug looj, raws li zoo raws li vim oxidation ntawm tej hexanol los yog castor roj. Qhov no compound kuj yog thaum ib tug qab zib fermentation nyob rau hauv lub xub ntiag ntawm lwj cheese. Nws yog ib tug byproduct ntawm tshuaj tiv thaiv no. Tsis tas li ntawd, caproic acid tej zaum yuav tsim nyob rau hauv qhov kev txiav txim ntawm streptococci. Mus nqa tawm nws extracting pom zoo fractionation ntawm crude butyric acid nrog ntxuav dej.
Nws yuav tsum tau hais tias ib tug loj tus naj npawb ntawm lub npe hu ntsev ntawm no compound. Nws tseem ceeb roj yog yus muaj los ntawm ib tug qab ntxiag fruity tsis hnov tsw, li ntawd lawv tau tau ntse siv raws li essences.
Nws tseem yog nqi hais lub luag hauj lwm ntawm nyeem fatty acids raws li lub hauj additives rau roj hmab, uas txhawb nws cov qauv thiab ua rau kom cov tsos ntawm cov tshiab lub zog. Yog li, txoj kev tshawb ntawm roj hmab zog ntawm so twb pom mus cuag lub siab tshaj plaws tau homogeneity ntawm cov khoom thaum ntxiv yog hexanoic acid. Nyob rau hauv daim ntawv thov no ntawm qhov uas tsis muaj molecular yuag daim ntawv ntawm no compound coj mus rau tus nqi qis tshaj kuj mus ntxov ntxov vulcanization, uas qhia ib tug siab ua si ntawm no acid.
Nyob rau hauv lub teb ntawm cosmetology feem ntau siv glycolic acid, uas muaj tus nqi qis tshaj molecular ceeb thawj los ntawm tag nrho cov alpha-hydroxy kua qaub. Qhov no tso cai rau lub substance rau nkag mus rau los ntawm lub epidermal barrier.
Glycolic acid, uas yuav yuav nyob rau lub tsev muag tshuaj, twb tau ntse siv los txo pigmentation thiab rau sib sib zog nqus peels. Nws yuav tsum tau muab sau tseg hais tias nws yog tseem txig eliminates wrinkles, uas ua rau ntawm daim tawv nqaij smoother thiab ntau dua ywj raws li ua ntau khaus collagen synthesis, thiab kuj ua rau lub active cell loj hlob.
Xav txog tej no los, nyob rau hauv lub teb ntawm cosmetology lug siv yog glycolic acid. Tus nqi ntawm cov khoom rau ntawm daim tawv nqaij khoom uas hais tias muaj nyob rau hauv nws cov nyob tus yeees yog ib tug compound npaj meej muaj nyob. Qhov no ua rau nws kim heev kev siv ntawm ntau yam cream thiab muab tshuaj pleev rau lub hauv paus ntawm no acid, tshwj xeeb tshaj yog nyob rau hauv cov poj niam nrog ib tug teeb meem los yog laus daim tawv nqaij.
