Dipropylene Glycol Dimethyl Ether oo leh CAS 111109-77-4
Dipropylene Glycol Dimethyl Ether oo la soo gaabiyay as DPGDME, oo leh lambar CAS ah 111109-77-4, waa dareere aprotic ah oo si caadi ah loo isticmaalo. Dareeraha Dpdme wuxuu leeyahay polarity dhexdhexaad ah, si fudud ayuu ugu milmi karaa biyaha, waxaana lagu milmi karaa inta badan dareereyaasha dabiiciga ah. Dipropylene glycol dimethyl ether waa dareere aad u fiican oo la jaanqaadaya "wajiga biyaha-organic". Dareeraha Dpdme waa dareere dhexdhexaad ah oo karkaraya, aan guban karin laakiin waa in laga fogeeyaa ololka furan ee heerkulka sare leh.
Dipropylene glycol dimethyl ether waa dareere deegaanka u fiican oo ujeeddooyin badan leh oo leh ur macaan oo jilicsan, xawaare ku habboon oo isbeddel ah, xasillooni kiimiko oo aad u fiican, milmi aad u fiican iyo badbaado sare oo caafimaadka aadanaha ah. Mareykanka iyo Midowga Yurub waxaa loo taxay inay yihiin dareere cagaaran oo aan HAP/NAP ahayn (aan khatar ku ahayn liiska wasakhowga hawada). Dipropylene glycol dimethyl ether 99.0 badanaa waxaa loo isticmaali karaa dahaarka biyaha ku salaysan iyo kuwa la daaweeyay.

Dipropylene glycol dimethyl ether waxaa si weyn loogu isticmaalaa goobo cilmi baaris oo kala duwan oo warshadeed iyo cilmi baaris ah sababtoo ah astaamaha "sunta yar, milmida sare iyo isbeddel yar":
Warshadaha dahaarka iyo khadku:Dipropylene glycol dimethyl ether, oo ah dareere ama dareere isku-dhafan, ayaa loo isticmaalaa dahaarka biyaha ku salaysan, dahaarka ku salaysan dareeraha iyo khad. Waxay hagaajin kartaa milmida resins-ka (sida resins-ka acrylic iyo resins-ka polyurethane), waxay kor u qaadi kartaa heerka iyo dhegdhegga dahaarka, isla markaana waxay yareyn kartaa sii deynta isku-dhafka dabiiciga ah ee kacsan (VOCs).
Walxaha nadiifinta iyo walxaha dufanka ka saara:Sababo la xiriira sifooyinkooda hydrophilic iyo lipophilic labadaba, waxaa loo isticmaali karaa qaacidooyinka "wakiilka nadiifinta biyaha ku salaysan" ee qaybaha elektaroonigga ah iyo qalabka saxda ah. Waxay si wax ku ool ah uga saari karaan wasakhda saliidda iyo haraaga qulqulka (haraaga qulqulka), mana mirqin karaan agabka salka (sida biraha iyo balaastikada).
Dhinaca daawada iyo sunta cayayaanka:Dareeraha Dpdme, oo ah "dareeraha/dareeraha isku-dhafan" ee maaddooyinka firfircoon ee daawooyinka ama sunta cayayaanka, ayaa loo isticmaalaa diyaarinta dareeraha afka laga qaato iyo sunta cayayaanka ee la isku ururiyo. Dipropylene glycol dimethyl ether waxay kor u qaadi kartaa milmida iyo xasilloonida maaddooyinka firfircoon iyadoo yareynaysa cuncunka jirka aadanaha ama dalagyada.
Isku-darka kiimikada iyo habka falcelinta:Dipropylene glycol dimethyl ether, oo ah dareere aprotic polar ah, ayaa beddeli kara dareereyaasha dhaqameed ee aadka u sunta badan waxaana loo isticmaali karaa falcelinta isku-darka dabiiciga ah (sida beddelka nucleophilic iyo falgallada katalytic), kuwaas oo kordhin kara heerka falgalka iyo wax-soo-saarka wax-soo-saarka.
Daryeelka shaqsiga ah iyo alaabada kiimikada maalinlaha ah:Dipropylene glycol dimethyl ether waxaa loo isticmaalaa xaddi yar oo lagu sameeyo alaabada daryeelka maqaarka iyo qurxinta (sida kareemada wejiga iyo cadarka) iyadoo ah dareere ama qoyaan, taasoo ka caawisa milmida maaddooyinka firfircoon ee saliidda ku milma (sida fitamiin E), iyadoo kor u qaadaysa dareenka maqaarka iyo xasilloonida alaabta.
