Cov txheej txheem ntawm Vanillin
Cov txheej txheem ntawm kev ua cov hmoov vanillin muaj ob peb kauj ruam, suav nrog kev tsim cov khoom siv raw, tshuaj synthesis, thiab purification.
Thawj kauj ruam hauv kev ua vanillin hmoov yog tsim cov khoom siv raw. Vanillin tuaj yeem pom hauv ntau qhov chaw ntuj, xws li vanilla pods, cloves, thiab balsam ntawm Peru. Txawm li cas los xij, vim qhov kev thov siab rau vanillin hauv kev lag luam khoom noj khoom haus, feem ntau ntawm vanillin siv niaj hnub no yog tsim los rau hauv chav kuaj siv petrochemicals xws li lignin.
Cov kauj ruam tom ntej yog tshuaj synthesis, qhov twg lignin hloov mus rau hauv vanillin. Cov txheej txheem tshuaj synthesis pib nrog kev sib cais ntawm coniferyl cawv los ntawm lignin. Coniferyl cawv yog lub tsev thaiv ntawm vanillin thiab tuaj yeem hloov tau yooj yim rau hauv vanillin los ntawm ntau cov tshuaj tiv thaiv. Txoj kev siv feem ntau siv rau kev sib txuas ntawm vanillin yog los ntawm oxidation ntawm coniferyl cawv siv tshuaj reagents xws li poov tshuaj permanganate thiab nitric acid.
Thaum kawg, vanillin uas yog tsim los yuav tsum tau purified kom tshem tawm tej impurities uas tej zaum yuav muaj. Cov txheej txheem purification muaj ob peb kauj ruam, nrog rau cov kuab tshuaj extraction, distillation, thiab crystallization. Lub vanillin yog thawj zaug muab rho tawm los ntawm cov tshuaj tiv thaiv sib tov siv cov kuab tshuaj xws li methanol lossis ethyl acetate. Tom qab ntawd lub resulting sib tov yog distilled kom tshem tawm cov kuab tshuaj uas tseem tshuav thiab impurities. Cov kauj ruam kawg suav nrog crystallization, qhov chaw purified vanillin txias thiab tso cai rau crystallize.
Cov txheej txheem ntau lawm ntawm vanillin hmoov koom nrog ntau cov kauj ruam nyuaj, suav nrog kev tsim cov khoom siv raw, tshuaj synthesis, thiab purification. Txawm hais tias vanillin tuaj yeem pom muaj nyob hauv qee qhov chaw, feem ntau ntawm vanillin siv niaj hnub no yog tsim los ntawm kev xav tau siab hauv kev lag luam khoom noj.
