YGlycerine vs Glycerol
Glycerol thiab glycerin yog ob lo lus uas ua rau ntau tus neeg tsis meej pem thiab siv sib hloov. Feem ntau, ob qho tib si muaj kev siv tib yam. Txawm hais tias lawv zoo li tib yam, muaj qhov sib txawv ntawm ob nqe lus. Feem ntau peb siv lub sij hawm glycerin, uas yog lub sij hawm coj mus muag rau cov compound glycerol, thiab muaj ob peb lwm qhov sib txawv ntawm ob.
Glycerol
Glycerol yog polyol molecule nrog cov mis molecular HOCH2CHOHCH2OH. Raws li IUPAC nomenclature, glycerol yog hu ua Propan-1, 2, 3-triol. Nws molar mass yog 92.09 g mol−1 Nws muaj peb pawg -OH txuas rau peb cais carbon atoms. Qhov no belongs rau tsev neeg cawv hauv organic chemistry. Nws yog cov kua nplaum uas tsis muaj xim. Tsis tas li ntawd nws yog odorless thiab qab zib nyob rau hauv saj. Cov qauv ntawm glycerol yog raws li hauv qab no.
Vim yog peb pawg-hydroxyl, glycerol molecule yog cov polar heev. Qhov no ua rau lawv soluble nyob rau hauv dej thiab lwm yam polar solvents. Glycerol tsim lipid nrog kev sib xyaw ntawm peb fatty acids. Cov pab pawg -OH ntawm glycerol thiab -COOH pawg ntawm fatty acids ua ester bonds, thiab tsim cov triglyceride. Yog li, glycerol yog lub caj qaum ntawm triglyceride. Txij li thaum triglycerides yog cov sib txuas hauv xab npum, glycerol yog qhov tseem ceeb hauv kev ua xab npum. Ntxiv mus, qhov no yog siv dav hauv kev siv tshuaj. Nws yog siv los ua cov ntsiav tshuaj-binding tus neeg sawv cev, muab lubrication thiab ua laxative. Glycerol yog ib qho kev kho mob rau kub hnyiab, tom, txiav, thiab psoriasis. Glycerol yog humectants; Yog li ntawd, nws yog siv nyob rau hauv moisturizers. Tsis tas li ntawd, glycerol yog siv los ua cov khoom siv hauv peb cov khoom siv niaj hnub xws li tshuaj txhuam hniav, shaving cream, khoom tu plaub hau, tshuaj ntxuav qhov ncauj, thiab lwm yam. khaws cia zaub mov. Glycerol yog qab zib cawv, yog li nws yog siv rau hauv cov khoom noj es tsis txhob qab zib kom muab lub qab zib saj. Nws muaj calories tsawg piv rau qab zib (27 calories ib diav tshuaj yej), yog li nws yog ib qho kev xaiv zoo rau qab zib. Glycerol yog siv los tsim phom hmoov thiab ntau yam khoom tawg. Nitroglycerin yog cov khoom tawg uas tsim los ntawm glycerol.
YGlycerine
Nov yog lo lus lag luam. Thaum muaj ntau dua 95% glycerol hauv cov khoom, nws yog hu ua glycerin. Txawm hais tias cov ntsiab lus tshuaj rau cov qauv no yuav tsum yog glycerol, rau kev siv glycerine feem ntau siv. Txawm li cas los xij, glycerol yog cov ntsiab lus tshuaj uas qhia tias muaj pes tsawg leeg hauv cov qauv. Glycerin yog siv rau feem ntau ntawm kev siv raws li cov xeev saum toj no hauv qab glycerol. Tab sis txij li, glycerin tsis muaj glycerol ntshiab; Nws tsis tuaj yeem siv rau qee lub hom phiaj uas cov ntshiab glycerol xav tau. Piv txwv li, thaum kho qhov txiav thiab hlawv, cov glycerol ntshiab yog xav tau.
Dab tsi yog qhov txawv ntawm Glycerin thiab Glycerol?
• Glycerin yog cov lus lag luam rau cov qauv uas muaj ntau dua 95% glycerin.
• Yog li, glycerin tsis muaj glycerol nkaus xwb.
• Kev siv ntawm ob qhov sib txawv heev. Glycerol yog siv rau kev siv kho mob, lub hom phiaj tshawb fawb qhov twg glycerol ntshiab yog xav tau. Thiab glycerin yog siv rau hauv tshuaj pleev ib ce thiab khoom noj txhua hnub.
