Glycerol, tseem hu ua glycerin lossis propane-1,2,3-triol

Glycerol, tseem hu ua glycerin lossis propane-1,2,3-triol, yog ib qho organic compound uas siv tau ntau yam thiab siv dav. Nws yog ib qho kua tsis muaj xim, tsis muaj ntxhiab, viscous nrog saj qab zib. Glycerol yog hygroscopic, txhais tau tias nws nyiam thiab tuav cov dej molecules los ntawm ib puag ncig ib puag ncig. Cov khoom no ua rau nws yog ib qho khoom xyaw tseem ceeb hauv ntau yam kev siv hauv kev lag luam, suav nrog cov tshuaj pleev ib ce, tshuaj, khoom noj, thiab cov khoom siv tu tus kheej.

Cov Khoom

Glycerol muaj qhov hnyav molecular li ntawm 92.09 g/mol. Nws yaj tau zoo heev hauv dej thiab muaj lub ntsiab lus kub ntawm 290 ° C. Cov tshuaj no paub txog nws qhov viscosity siab thiab hygroscopic xwm, uas ua rau nws khaws cov dej noo tau zoo. Cov yam ntxwv no ua rau glycerol ua ib qho humectant zoo heev, muaj peev xwm tswj cov dej noo hauv ntau yam khoom.

Cov Txheej Txheem Tsim Khoom

Glycerol tuaj yeem tsim tau los ntawm ntau txoj kev, suav nrog kev tsim tshuaj lom neeg thiab kev rho tawm ntuj. Ib txoj kev siv ntau yog hydrolysis ntawm cov rog thiab roj, uas ua rau glycerol ua cov khoom seem. Lwm txoj kev yog txoj kev tsim propylene, uas suav nrog cov txheej txheem xws li chlorination thiab oxygenation. Tsis tas li ntawd, glycerol tuaj yeem tsim tau los ntawm kev saponification ntawm triglycerides nrog sodium hydroxide, ua rau glycerol thiab xab npum. Nyob rau hauv xyoo tas los no, kev lag luam biodiesel tau dhau los ua qhov tseem ceeb ntawm glycerol, tsim nws ua cov khoom seem thaum lub sijhawm transesterification ntawm cov roj zaub.

Cov ntawv thov

Glycerol qhov kev hloov pauv tau pom tseeb hauv nws cov kev siv dav dav thoob plaws ntau yam lag luam:

Tshuaj pleev ib ce thiab kev saib xyuas tus kheejGlycerol yog ib qho khoom tseem ceeb hauv ntau yam khoom siv pleev kom zoo nkauj, suav nrog cov tshuaj pleev, tshuaj pleev, thiab cov khoom siv tu plaub hau. Nws pab tswj kom daim tawv nqaij noo thiab txhim kho qhov zoo nkauj thiab kev nthuav dav ntawm cov tshuaj pleev. Raws li Pawg Sab Laj Saib Xyuas Khoom Siv Kho Mob Tus Kheej, glycerol siv rau hauv ntau dua 23,366 yam khoom siv pleev kom zoo nkauj, feem ntau ntawm qhov concentration txog li 99.4%.

Cov TshuajGlycerol siv ua cov tshuaj yaj, cov khoom qab zib, thiab cov tshuaj humectant hauv ntau yam tshuaj. Nws kuj yog ib feem ntawm cov tshuaj hnoos, tshuaj pleev, thiab cov tshuaj suppositories. Hauv kev siv kho mob, glycerol siv los kho cem quav thiab txo qhov siab hauv cov neeg mob uas muaj mob xws li mob hlwb thiab mob hlwb.

Kev Lag Luam Khoom NojGlycerol ua haujlwm ua cov khoom ntub dej, cov kuab tshuaj, thiab cov khoom qab zib hauv cov khoom noj. Nws pab tswj cov qauv thiab cov dej noo hauv cov khoom xws li khoom qab zib, khoom ci, thiab ice cream. Tsis tas li ntawd, glycerol siv rau hauv kev tsim cov tshuaj khaws cia zaub mov thiab cov tshuaj tsw qab.

Kev Siv Hauv Kev Lag LuamGlycerol siv ua roj nplua nyeem thiab tshuaj tiv thaiv kev khov hauv kev siv hauv kev lag luam. Nws kuj yog ib qho tseem ceeb hauv kev tsim cov yas thiab cov resins.

Cov Ntaub Ntawv Txog Kev Nyab Xeeb

Feem ntau, glycerol yog ib yam khoom siv uas siv tau rau hauv cov khoom noj, tshuaj pleev ib ce, thiab tshuaj. Txawm li cas los xij, nws tuaj yeem ua rau muaj kev phiv me me xws li mob taub hau, kiv taub hau, thiab o thaum noj ntau dhau. Thaum siv rau ntawm daim tawv nqaij, glycerol zoo rau kev noj qab haus huv tab sis qee tus neeg yuav ua rau liab lossis khaus. Hauv kev siv kho mob, cov tshuaj glycerol suppositories thiab enemas tau pom zoo rau kev siv tsis tas yuav muaj daim ntawv yuav tshuaj los ntawm US FDA.

Kev Khaws Cia thiab Kev Ua Haujlwm

Glycerol yuav tsum khaws cia rau qhov chaw txias thiab qhuav, kom deb ntawm tshav ntuj ncaj qha thiab qhov chaw kub. Nws yog ib qho tseem ceeb uas yuav tsum kaw lub thawv kom nruj kom tiv thaiv kev nqus dej noo thiab kev ua qias tuaj. Rau kev siv hauv kev lag luam, glycerol feem ntau yog ntim rau hauv cov thoob lossis cov thawv loj. Kev tuav thiab khaws cia kom zoo yog qhov tseem ceeb kom tswj tau qhov zoo thiab kev nyab xeeb ntawm cov khoom.

Cov Qauv Zoo

Glycerol raug rau cov qauv zoo nruj kom ntseeg tau tias nws huv thiab haum rau ntau yam kev siv. Cov koom haum xws li Tebchaws Meskas Pharmacopeia (USP), European Pharmacopoeia (EP), thiab Food Chemicals Codex (FCC) tau tsim cov lus qhia rau kev tsim thiab siv glycerol. Cov qauv no suav nrog cov lus qhia rau cov ntsiab lus glycerol, xim, tsw, dej, thiab qhov muaj cov khoom tsis huv xws li cov hlau hnyav thiab cov kuab tshuaj seem.

Hauv kev xaus lus, glycerol yog ib qho tshuaj sib xyaw ua ke uas muaj ntau yam kev siv vim nws cov yam ntxwv tshwj xeeb. Nws cov txheej txheem tsim khoom, kev nyab xeeb, thiab kev ua raws li cov qauv zoo ua rau nws yog ib qho khoom xyaw txhim khu kev qha thiab tseem ceeb hauv ntau yam lag luam.
