Azelaic acid yog ib txwm tshwm sim ncaj nraim- saw aliphatic dicarboxylic acid nrog cov mis molecular C₉H₁₆O₄. Thaum pib, nws yog feem ntau tau los ntawm oxidation ntawm ntuj zaub roj. Vim muaj ob pawg carboxyl nyob rau hauv nws cov molecule - uas confer chemical reactivity - nws yog Ameslikas siv raws li ib tug tseem ceeb raw khoom nyob rau hauv organic synthesis thiab tshuaj tsim tshuaj. Nrog rau kev nce qib hauv cov organic thiab fatty acid chemistry, cov txheej txheem ntau lawm tau maj mam hloov los ntawm kev rho tawm yooj yim los ntawm cov khoom siv ntuj tsim rau kev lag luam - nplai synthesis.
Txij li thaum xyoo pua 20th, kev lag luam kev siv ntawm azelaic acid tau nthuav dav, tau txais kev txaus siab tshwj xeeb hauv cov teb ntawm polymers thiab tshuaj zoo. Muaj peev xwm ua tau raws li polycondensation nrog diols los tsim polyesters thiab esterification los tsim ntau yam azelate esters, nws yog siv los tsim cov polyesters, plasticizers, lubricants, thiab lwm yam khoom siv tshuaj. Raws li cov ntaub ntawv polymer kev lag luam tau hloov zuj zus, kev tshawb fawb rau hauv aliphatic dicarboxylic acids tau tob zuj zus; azelaic acid, nrog rau nws qhov nruab nrab carbon saw ntev thiab ob pawg carboxyl, tuav tus nqi tseem ceeb hauv cov khoom tsim qauv.
Azelaic acid kuj tau pom kev txhim kho tseem ceeb hauv kev saib xyuas tus kheej thiab kev tu tawv nqaij. Raws li kev tshawb fawb txog kev ua haujlwm ntawm cov khoom siv tawv nqaij tau ua tiav, azelaic acid tau nce ntxiv rau hauv cov khoom siv tawv nqaij. Tsis zoo li nws cov ntawv thov kev lag luam, nws siv hauv kev tu tawv nqaij yog tsav los ntawm cov tawv nqaij tshwj xeeb - cov khoom ua kom txias, ua rau kev txhim kho cov khoom sib txawv xws li cov qauv yooj yim mus rau cream, gels, thiab serums. Nyob rau hauv tas li ntawd, kev tshawb fawb txog nws stability, formulation compatibility, thiab pom kev siv concentrations intensified.
Nyob rau hauv xyoo tas los no, kev nce qib ntawm ntsuab chemistry thiab bio- cov ntaub ntawv raws li tau nthuav dav ntxiv rau kev tsim thiab siv azelaic acid. Thaum cov kev cai petrochemical ib txwm tseem yog txoj hauv kev tsim khoom tseem ceeb, kev tshawb fawb txog kev tsim cov azelaic acid los ntawm cov khoom noj tauj dua tshiab -xws li cov roj zaub - tau txais txiaj ntsig. Cov kev tshawb fawb tseem ceeb tau hloov pauv los ntawm tsuas yog nce cov txiaj ntsig los txo qis kev siv hluav taws xob thiab los ntawm - cov khoom, thaum tib lub sijhawm txhim kho cov khoom purity thiab kev ruaj ntseg ntau lawm. Saib ua ntej, azelaic acid khaws cia muaj peev xwm loj hlob hauv cov ntaub ntawv polymer, cov tshuaj zoo, thiab kev saib xyuas tus kheej, nrog rau cov cuab yeej siv ntsuab tsim tawm los ua qhov tseem ceeb ntawm kev tshawb fawb yav tom ntej.
