1,2-Propylene Glycol CAS NO.57-55-6
Tlhaloso ea Lihlahisoa
- 1,2 Propylene glycol e bohareng ba bactericide difenoconazole le thepa e tala ea bohlokoa bakeng sa polyester e sa tsitsang, epoxy resin, le polyurethane resin. Chelete e karolong ena e etsa hoo e ka bang 45% ea kakaretso ea tšebeliso ea 1,2 propylene glycol. Poly Ester ena ea unsaturated e sebelisoa haholo ho koahela holim'a metsi le lipolasetiki tse matlafalitsoeng. 1,2 Propylene glycol e na le viscosity e ntle le hygroscopicity, 'me ha e na chefo, kahoo e sebelisoa haholo e le mongobo o monyang, antifreeze, lubricant le solvent ho indasteri ea lijo, meriana le litlolo. Ka indasteri ea lijo, haholo-holo e sebelisoa e le emulsifier ea lijo; ka nako e ts'oanang ke solvent e babatsehang bakeng sa li-seasonings le li-pigments.
- Ts'ebetso ea ho ntšoa ha 1,2 propylene glycol ke karolo ea tekheniki ea karohano ea lik'hemik'hale. Ts'ebetso ena e sebelisa litšoaneleho tseo letsoai la diminerale le leng bonolo ho li belisa, athe matsoai a organic acid ka har'a moro oa propylene glycol ha ho bonolo ho khanya. Palo e loketseng ea asiti e inorganic e ekeletsoa ho propylene glycol belisoa moro ho nka sebaka sa organic acid matsoai ka belisoa moro le manyolo acid. Letsoai le tsamaisanang le mineral acid le hlahisoa; moro oa belisoa o tsitsitse, e le hore letsoai la diminerale le khanye, 'me le arohane le moro oa belisoa; moro o tsitsitseng o fetoha propylene glycol, succinic acid, lactic acid, acetic acid, glycerol le 2,3-butane Motsoako oa joala, vacuum distillation ea motsoako ho fumana lihlahisoa tsa karolo ka 'ngoe. Ka indasteri ea meriana, propylene glycol e atisa ho sebelisoa e le solvent, softener le excipient bakeng sa ho etsa litlolo le litlolo tse sa tšoaneng. Ka lebaka la ho lumellana ha eona hantle le linoko tse fapa-fapaneng, e boetse e sebelisoa e le solvent le softener bakeng sa litlolo.Propylene glycol e boetse e sebelisoa e le moisturizer ea koae, antifungal agent, thepa ea ho lokisa lijo e tlotsang oli le lijo tse tšoaeang enke solvent. Tharollo ea metsi ea propylene glycol ke antifreeze e sebetsang hantle.
