Cov Ntawv Thov
1. Polymer thiab Resin Raug
Crotonic acid yog qhov tseem ceeb monomer hauv kev tsim cov copolymers thiab resins.
Siv nyob rau hauv copolymerization nrog vinyl acetate, acrylates, thiab lwm cov monomers los tsim cov polymers uas tsim cov nplaum, dej tsis kam, thiab thermal ruaj khov.
Xws copolymers tau siv dav hauv cov txheej txheej, cov nplaum nplaum, cov kab xev, thiab xim pleev xim rau.
2. Nruab nrab hauv cov xwm txheej organic
Ua hauj lwm ua lub tsev thaiv uas muaj cov khoom siv tshuaj lom neeg zoo, agnchemicals, thiab kws tshuaj.
Qhov kev sib tw ob chav thiab carboxylic acid ua haujlwm tso cai rau ntau cov kev hloov pauv roj, xws li Esterification, Hydrogenation, Halogenation, thiab Michael ntxiv.
3. Tshuaj siv tshuaj
Siv ua ib qho tseem ceeb lossis reagent nyob rau hauv synthesis ntawm cov khoom xyaw tshuaj muaj zog (APIs).
Kev ua haujlwm ntawm cov derivatives ntawm crotonic acid muaj nyob rau hauv anti-inflammial, antimicrobial, thiab anticancer kev tshawb fawb.
4. Flavors thiab ntxhiab
Txawm hais tias Crotonic acid nws tus kheej muaj lub ntsej muag ntse, tsis muaj ntxhiab tsw, nws cov tshuaj estre (piv txwv li, crotonates) yog siv nyob rau hauv cov tshuaj tsw qab.
Crotonate Esters muaj cov txiv hmab txiv ntoo, qab ntxiag aromas thiab tau koom nrog cov tshuaj tsw qab thiab cov khoom noj tsw qab.
5. Agnaphical synthesis
Ua txhaum ua cov khoom siv raw rau kev sib xyaw ntawm cov tshuaj tua kab, tshuaj tua kab, thiab cog qoob loo loj hlob.
Cov pab pawg tsis tsim nyog thiab cov pab pawg carboxyl ua nws haum rau kev sib koom tes rau hauv cov molecules molecules.
Cov txiaj ntsig
1. Txhim kho cov pab pawg ua haujlwm
Lub trans muab cov nyiaj sib tw ob chav thiab cov roj carboxylic acid pawg tso cai rau ntau yam tshuaj lom neeg xws li.
Haum rau cov kev xav ntxiv, polymerization, thiab derivatization, ua rau nws muaj feem cuam tshuam ntau yam.
2. Txhim kho cov khoom siv
Cov ntawv copolymers muaj cov acrotonic acid tau ua kom zoo nkauj zaj duab xis-tsim muaj peev xwm, kev ua yeeb yam, hardness, thiab hnyav tsis kam.
Qhov zoo tagnrho rau cov txheej txheem ua tau zoo thiab cov nplaum hauv kev lag luam.
3. Biodegradity
Crriconic acid thiab nws cov polymers tuaj yeem yog biodegradable, nyob ntawm cov qauv.
Qhov no ua rau nws muaj nuj nqis nyob rau hauv ib puag ncig cov ntaub ntawv phooj ywg thiab kev siv chemistreable.
4. Nqi siv tau zoo thiab ua lag luam
Nws yog qhov pheej yig, npaj tau ntau yam tshuaj lom neeg, ua rau nws siv rau kev siv cov ntawv thov loj.
Tag
Crotonic acid (CAS 10-93-7) yog ib tug heev ntau yam tsis zoo carboxylic acid uas yog cov tshuaj, duab, thiab tsw / ntxhiab. Nws cov qauv tshuaj ua rau nws tau ua tus yuam sij tseem ceeb rau ntau qhov kev cuam tshuam, thaum nws muaj txiaj ntsig zoo - ua rau nws muaj txiaj ntsig rau kev tshawb fawb thiab kev tsim khoom lag luam. Raws li muaj kev ruaj khov thiab kev ua tau zoo nyob hauv cov khoom siv tsav tsheb thiab cov roj ntsha, crotonic acid tseem yog qhov tseem ceeb ntawm cov ntawv thov sib txawv.
