Introduction
Glycerol, tseem hu ua glycerin, yog cov organic compound thiab ib qho yooj yim polyol compound. Nws yog ib qho tsis muaj kob, tsw ntxhiab, qab zib - Sasting, viscous kua thiab tsis- ua rau. Tus pob zeb glycerol yog tam sim no nyob rau hauv lipids hu ua glycerides. Vim nws cov tshuaj tua kabmob thiab cov tshuaj tiv thaiv kab mob, nws yog dav siv nyob rau hauv kev mob thiab hlawv cov kev kho pom zoo los ntawm FDA. Hloov siab, nws tseem siv los ua cov kab lis kev cai me me kab lis kev cai. Nws tuaj yeem ua haujlwm zoo rau kev ntsuas cov kab mob. Nws tseem dav siv raws li lub qab zib nyob rau hauv kev lag luam khoom noj khoom haus thiab raws li kev nyiam kev nyiam ua yeeb yam.

Cov Khoom Siv Lub Cev
| Kev tshwm sim | Glycerol yog ib qho tsis muaj kob, tsis muaj ntxhiab, kua muag ntawm chav sov. Nws muaj qab zib, uas yog ib qho ntawm nws cov yam ntxwv uas muajable. |
| Melting taw tes | 17,8℃(64.0 Degree F) |
| Kub taw tes | 290℃(554℃f) ntawm kev siab siab, tab sis nws decomposes me ntsis nyob ib ncig ntawm qhov kub no. Nyob rau hauv kev txo qis, nws tuaj yeem ua kom distilled yam tsis muaj kev txiav txim siab. |
| Ceev | 1.26 g / ml ntawm 25 degree. Nws qhov tseem ceeb tshaj plaws yog vim muaj ntau pawg hydroxyl uas ua rau muaj kev sib txuam nrog hydrogen hydrogen bonding. |
| So | Glycerol yog soluble heev hauv dej. Nws ua cov ntawv sib khi hydrogen muaj zog nrog cov roj molecules, tso cai rau nws kom yaj yooj yim. Nws tseem yog miscible nrog ntau polar organic cov kuab tshuaj xws li ethanol thiab methanol. Txawm li cas los xij, nws yog immiscible nrog tsis- polar cov kuab tshuaj zoo li hydrocarbons (piv txwv li, benzene, hexane). |
Cov Ntawv Thov
Kev Lag Luam Khoom Noj
Glycerol yog siv los ua khoom noj ntxiv. Nws ua haujlwm raws li kev nyiam, tiv thaiv cov zaub mov ntawm kom qhuav thiab tswj nws cov ntsiab lus ya raws. Nws yog feem ntau siv nyob rau hauv bakery cov khoom, tswm ciab, thiab khoom noj siv mis. Nws tseem ua raws li lub qab zib, cov tuab dua, thiab cov kuab tshuaj rau cov kua thiab xim hauv cov khoom noj.
Tshuaj pleev ib ce thiab Kev Saib Xyuas Tus Kheej
Hauv cov tshuaj pleev ib ce, glycerol yog cov khoom tseem ceeb. Nws ua haujlwm rau cov neeg nyiam ua kom cov tawv nqaij thiab cov plaub hau ntub dej noo, nrog rau cov tuab thiab hnyav. Nws pom nyob rau hauv cream, tshuaj, zawv plaub hau, thiab lwm yam khoom lag luam, pab txhim kho lawv cov kev ntxhib los mos thiab ua haujlwm tau zoo.
Kws Kev Lag Luam:
Glycerol yog siv nyob rau hauv cov kws ua tshuaj yog cov kuab tshuaj, kev nyiam ua, thiab qab zib thiab qab zib hauv qhov ncauj. Nws kuj yog siv rau hauv kev npaj ua kom zoo los txhim kho cov tshuaj nkag mus rau hauv daim tawv nqaij thiab muab cov nyhuv soothing. Ib qho ntxiv, nws tuaj yeem siv los ua kev sib xyaw ua ke hauv cov kev daws teeb meem.
Muaj Cov Ntawv Thov
Glycerol yog siv nyob rau hauv kev tsim cov plastics thiab resins, xws li alkyd resins siv hauv cov xim thiab pleev xim. Nws tseem siv rau hauv kev tsim cov khoom tawg (piv txwv li, nitroglycerin, uas yog tsim los ntawm glycerol thiab roj nplua nyeem, thiab hauv kev ua luam yeeb ua kom cov khoom lag luam luam yeeb noo noo.
