1,2-Propylene Glycol CAS NO.57-55-6
Incazelo Yemikhiqizo
- 1,2 I-Propylene glycol emaphakathi ye-bactericide i-disenoconazole kanye nempahla ebalulekile ye-polyester engagcwalisiwe, i-epoxy resin, ne-polyurethane resin. Inani kulesi sici libalelwa ku-45% wengqikithi yokusetshenziswa kwe-1,2 propylene glycol. Le poly Ester engagcwalisiwe isetshenziswa kabanzi embotsheni engaphezulu namapulasitiki aqinisiwe. I-1,2 I-Propylene glycol ine-viscosity enhle ne-hygroscopicity, futhi ayinabo ubuthi, ngakho-ke isetshenziswa kabanzi njengento emunca umswakama, i-antifreeze, i-lubricant kanye ne-solvent ezimbonini zokudla, zemithi nezimonyo. Embonini yokudla, isetshenziswa kakhulu njenge-emulsifier yokudla; ngesikhathi esifanayo iyi-solvent enhle kakhulu yezinongo nezingulube.
- Inqubo yokukhipha i-1,2 propylene glycol ingeyomkhakha wezobuchwepheshe wokuhlukaniswa kwamakhemikhali. Le nqubo isebenzisa izici ukuthi usawoti we-mineral acid usawoti kulula ukuzicwebisa, kuyilapho usawoti we-organic acid ku-propylene glycol fermentation broth akulula ukucwebezela. Inani elifanele le-asidi ye-inorganic yengezwa kumhluzi we-propylene glycol fermentation ukuze esikhundleni sikasawoti we-asidi ephilayo emhluzweni wokuvutshelwa nama-asidi aphilayo. Usawoti we-mineral acid ohambelana nawo uyakhiqizwa; umhluzi wokuvutshelwa ugxiliwe, ukuze usawoti wamaminerali acwebezelise, futhi uhlukaniswe nomhluzi wokuvutshelwa; umhluzi wokuvutshelwa ogxilile uba yi-propylene glycol, i-succinic acid, i-lactic acid, i-acetic acid, i-glycerol ne-2,3-butane Ingxube yotshwala, i-vacuum distillation yengxube ukuze uthole imikhiqizo yengxenye ngayinye. Embonini yezemithi, i-propylene glycol ivame ukusetshenziswa njenge-solvent, softener kanye ne-excipient ekwenzeni ama-ointments ahlukahlukene kanye namafutha. Ngenxa yokuhambisana kwayo okuhle nezinongo ezihlukahlukene, iphinde isetshenziswe njenge-solvent kanye ne-softener yezimonyo.I-Propylene glycol iphinde isetshenziswe njenge-moisturizer kagwayi, i-antifungal agent, imishini yokucubungula ukudla yokugcoba amafutha kanye ne-solvent ye-inki yokumaka ukudla. Isixazululo esinamanzi se-propylene glycol siyi-antifreeze esebenzayo.

Isicelo
- Njenge-solvent, ingancibilikisa izithasiselo zokudla ezingancibiliki emanzini njengama-preservatives, ama-pigment, ama-antioxidants, njll., bese wengeza ekudleni; ine-hygroscopicity eqinile, futhi inemiphumela yokuthambisa kanye ne-anti-freezing ekudleni.
- Njengomuntu ophethe izidakamizwa kanye ne-ejenti yezidakamizwa eyimbudumbudu. Ingasetshenziswa njenge-humectant, softener, solvent, njll.
- Embonini kagwayi, ingasetshenziswa njenge-flavour kagwayi, i-moisturizer kagwayi, i-preservative, njll.
- Embonini yokudla, isetshenziswa njengesithako se-flavour, umbala wokudla, izinto ezithambisayo zokupakisha ukudla, kanye nama-anti-sticking agents.
