Product Description:
Glycerin, hu ua glycerol hauv cov qauv hauv tebchaws, yog xim tsis muaj xim, tsis muaj ntxhiab, qab zib-tswnyob rau hauv cov khoom organic nrog cov tsos ntawm cov pob tshab kua nplaum.Feem ntau hu ua glycerol.Glycerol, tuaj yeem nqus dej noo los ntawm huab cua, tab sis kuj nqus hydrogen sulfide, hydrogen cyanide thiab sulfur dioxide.
Product Properties thiab Stability:
1.Miscible nrog dej, cawv thiab lwm yam kuab tshuaj organic, tuaj yeem yaj cov roj zaub, roj tsiaj, cov khoom siv ntuj tsim thiab qee cov khoom siv hluavtaws.Nws muaj ntxhiab tsw zoo li ethanol.Tsis muaj corrosive rau hlau.
2.Chemical zog: zoo ib yam li ethanol, oxidation generates propionaldehyde, ntxiv oxidation generates propionic acid.Dehydrate nrog sulfuric acid los tsim propylene.
3. Tsawg toxicity.Cov nyhuv physiological zoo ib yam li ethanol, tshuaj loog thiab stimulation ntawm mucous daim nyias nyias yog me ntsis zog dua ethanol.Toxicity kuj loj dua ethanol, muaj peev xwm tua kab mob yog peb zaug muaj zog dua ethanol.Olfactory threshold concentration ntawm 73.62mg / m3.TJ 36-79 qhia tias qhov siab tshaj plaws tso cai nyob rau hauv huab cua ntawm lub rooj cob qhia yog 200mg / m3.
4.Stability: ruaj khov
5.Cov tshuaj txwv tsis pub: muaj zog oxidising cov neeg ua haujlwm, anhydrides, acids, halogens.
6.Kev phom sij ntawm polymerization: Tsis yog-polymerisation.
Khoom siv:
1.Propanol yog siv ncaj qha los ua cov kuab tshuaj los yog hluavtaws propyl acetate, uas yog siv los ua cov kuab tshuaj rau cov xim, luam ntawv inks, tshuaj pleev ib ce, thiab lwm yam. Nws yog siv rau hauv kev tsim cov n-propylamine, ib qho nruab nrab ntawm cov tshuaj thiab tshuaj tua kab, thiab yog siv nyob rau hauv zus tau tej cov khoom noj additives thiab hluavtaws fragrances.Propanol hauv kev lag luam kws tshuaj rau kev tsim cov tshuaj probenecid, sodium valproate, erythromycin, qaug dab peg Jianan, adhesive haemostatic agent BCA, propylthiothiamine, 2,5-pyridinedicarboxylic acid dipropyl ester;theem propanol synthesized esters, siv nyob rau hauv cov khoom noj additives, plasticisers, fragrances, thiab hais txog;n-propanol derivatives, tshwj xeeb tshaj yog di-n-propylamine hauv kev tsim tshuaj thiab tshuaj tua kab muaj ntau daim ntawv thov rau kev tsim cov tshuaj tua kab aminesulphonamide, mycodamine, isopropanolamine, mirex, thiab lwm yam.Nws yog siv los tsim cov tshuaj tua kab xws li aminesulphurin, bactrim, isoproterenol, mirex, sulphadoxine, fluroxypyr thiab lwm yam.
2.Nws yog siv los ua kuab tshuaj rau cov roj zaub, roj hmab ntuj thiab cov resins, qee cov khoom siv hluavtaws, ethyl cellulose thiab polyvinyl butyral.Kuj tseem siv rau hauv cov tshuaj tsuag nitro, xim, tshuaj pleev ib ce, tshuaj ntxuav hniav, tshuaj tua kab, fungicide, number case, plastics, antifreeze, adhesives thiab lwm yam.
3. Feem ntau siv los ua cov kuab tshuaj.Nws tuaj yeem siv los ua cov kuab tshuaj pleev xim, luam ntawv number case, tshuaj pleev ib ce, thiab lwm yam, siv rau hauv kev tsim tshuaj, tshuaj tua kab, intermediates n-propylamine, siv rau hauv kev tsim cov khoom noj additives, hluavtaws spices thiab lwm yam.Propanol yog dav siv nyob rau hauv kev lag luam tshuaj, khoom noj khoom haus additives, plasticisers, txuj lom thiab ntau lwm yam.
4.Siv raws li cov kuab tshuaj thiab nyob rau hauv kws tshuaj, xim thiab tshuaj pleev ib ce, thiab lwm yam.
Cov ntawv khaws cia khoom:
1. Khaws rau hauv qhov chaw txias, cua txias.
2. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov.
3.Qhov kub cia yuav tsum tsis pub tshaj 37 ° C.
4. Khaws lub thawv kaw.
5.Nws yuav tsum tau muab cais los ntawm cov neeg ua haujlwm oxidising, acids, halogens thiab cov khoom siv tau, thiab yuav tsum tsis txhob sib xyaw.
6.Siv cov khoom tawg-pov thawj teeb pom kev zoo thiab cov chaw ua pa.
7. Txwv tsis pub siv cov cuab yeej siv tshuab thiab cov cuab yeej uas yooj yim los tsim cov pob zeb.
8.Qhov chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev thiab cov khoom siv vaj tse tsim nyog.
