Dipropylene Glycol Dimethyl Ether e nang le CAS 111109-77-4
Dipropylene Glycol Dimethyl Ether e kgutsufaditsweng as DPGDME, e nang le cas no 111109-77-4, ke solvent e sebelisoang haholo polar aprotic. Dpdme solvent e na le polarity e itekanetseng, e qhibiliha habonolo metsing, 'me e ka kopanngoa le li-solvent tse ngata tsa tlhaho. Dipropylene glycol dimethyl ether ke solvent e ntle e lumellanang le "metsi-organic phase". Dpdme solvent ke solvent e belang bohareng, e sa cheseng empa e lokela ho bolokoa hole le malakabe a bulehileng a mocheso o phahameng.
Dipropylene glycol dimethyl ether ke tharollo e sebetsang ka merero e mengata tikolohong e nang le monko o monate o fokolang, lebelo le loketseng la ho fetoha ha mocheso, botsitso bo botle ba lik'hemik'hale, ho qhibiliha ho babatsehang le polokeho e phahameng bophelong ba batho. United States le European Union li thathamisitsoe e le litharollo tse tala bakeng sa tse seng tsa HAP/NAP (tse seng kotsi lenaneng la tšilafalo ea moea). Dipropylene glycol dimethyl ether 99.0 hangata e ka sebelisoa ho lipente tse thehiloeng metsing le tse phekotsoeng.

Dipropylene glycol dimethyl ether e sebelisoa haholo mafapheng a fapaneng a lipatlisiso tsa indasteri le tsa mahlale ka lebaka la litšobotsi tsa eona tsa "chefo e tlase, ho qhibiliha ho hoholo le ho feto-fetoha ho tlase":
Liaparo le indasteri ea enke:Dipropylene glycol dimethyl ether, e le solvent kapa co-solvent, e sebediswa ho dikoahelo tse thehilweng metsing, dikoahelong tse thehilweng ho solvent le enkeng. E ka ntlafatsa ho qhibiliha ha di-resin (tse kang di-resin tsa acrylic le di-resin tsa polyurethane), ya ntlafatsa ho leka-lekana le ho kgomarela ha dikoahelo, mme ka nako e le nngwe ya fokotsa ho ntsha ha metswako ya organic e feto-fetohang (VOCs).
Lisebelisoa tsa ho hloekisa le tsa ho tlosa mafura:Ka lebaka la thepa ea tsona ea ho hema metsi le ea lipophilic, li ka sebelisoa mefuteng ea "sesebelisoa sa ho hloekisa se thehiloeng metsing" bakeng sa likarolo tsa elektroniki le lisebelisoa tse nepahetseng. Li ka tlosa matheba a oli le masala a phallo (masalela a phallo), 'me ha li senye thepa ea motheo (joalo ka litšepe le polasetiki).
Lefapheng la meriana le chefo e bolaeang likokoanyana:Sehlahisoa sa Dpdme, e le "solvent/co-solvent" bakeng sa metsoako e sebetsang ea meriana kapa chefo e bolaeang likokoanyana, se sebelisoa ho lokiseng metsi a nooang le chefo e bolaeang likokoanyana e ka emulsifiable. Dipropylene glycol dimethyl ether e ka ntlafatsa ho qhibiliha le botsitso ba metsoako e sebetsang ha e ntse e fokotsa ho teneha 'meleng oa motho kapa lijalo.
Tšebetso ea lik'hemik'hale le mokhoa oa karabelo:Dipropylene glycol dimethyl ether, e le solvent ya polar aprotic, e ka nkela disolvent tsa setso tse nang le chefo e ngata sebaka mme ya sebediswa dikarabelong tsa tlhahiso ya organic (tse kang ho nkela sebaka ha nucleophilic le dikarabelo tsa catalytic), tse ka eketsang sekgahla sa karabelo le chai ya sehlahiswa.
Tlhokomelo ea botho le lihlahisoa tsa lik'hemik'hale tsa letsatsi le letsatsi:Dipropylene glycol dimethyl ether e sebediswa ka bongata bo bonyenyane dihlahisweng tsa tlhokomelo ya letlalo le ditlolo (tse kang di-cream tsa sefahleho le dinkgisamonate) e le sethapolli kapa setlolo se futhumatsang letlalo, se thusang ho qhibidihisa metswako e sebetsang e qhibilihang ka oli (e kang vithamine E), ha ka nako e ts'oanang se ntlafatsa maikutlo a letlalo le botsitso ba dihlahiswa.
