Polyethylene Glycol (PEG) Synthesis Solution
Dareen-celinta polymerization-ka waxay ku dhejiyaan baahiyo sarreeya waxqabadka wareejinta kulaylka iyo awoodda isku-dhafka ee reactors. Dhaliilaha ka dhalanaya fal-celiyeyaasha dufcaddii dhaqameed ee dhinacyadan waxay noqdeen mid ka mid ah caqabadaha lagu gaadhayo polymers-ka waxqabadka sarreeya. Dhanka kale, reactors microchannel waxay awood u siin kartaa socodka miisaanka yar ee wejiyada badan ee la xakameyn karo, kor u qaadida isku dhafka, wareejinta tirada badan, iyo hababka wareejinta kulaylka inta lagu jiro falcelinta polymerization. Waxay si adag u xakameeyaan wakhtiga falcelinta oo ay gaadhaan isu imaatinka cutubyada falcelinta, si ay si fiican uga gudbaan caqabadahan. Marka la barbar dhigo reactors Dufcaddii dhaqameed, sifooyinkani waxay siinayaa reactors microchannel faa'iidooyin la taaban karo ee lagu xakameynayo qaybinta miisaanka molecular polymer, fududaynta xaaladaha falcelinta, hagaajinta xulashada falcelinta, iyo nidaaminta qaab dhismeedka molecular polymer iyo qaab-dhismeedka macroscopic.
Polyethylene glycol (PEG) waa polymer biyo-milmi leh oo laga sameeyay ethylene oxide iyo ethylene glycol. molecule PEG waxa ku jira tiro badan oo ah kooxaha ethoxy, kuwaas oo samayn kara bonds hydrogen biyo iyo qas biyo in saamiga kasta. PEG waa mid fudud saameynteeda, waxay keentaa falcelin xun oo yar, waxayna haysataa rajooyin suuqeed oo ballaaran oo ka faa'iideysanaya dawooyinka. Waqtigan xaadirka ah, wax-soo-saarka cabbirka-warshadaha ee qaybinta cidhiidhiga ah ee PEG guud ahaan waxay isticmaashaa fal-celiyeyaasha dufcada dhaqameed ee polymerization. Iyadoo habkani uu soo saari karo PEG oo leh tusaha kala firdhisanaanta ee ka hooseeya 1.05, alaabtu wali waa isku dhafka miisaannada unugyada kala duwan. Xataa marka lagu hoos jiro agabka cayriin ee nadiifka ah iyo xaaladaha habsocodka anhydrous adag, polymerization ee reactors Dufcaddii dhaqameed ma gaari karo hal-qeybin PEG. Keliya reactors microchannel ayaa ku abuuri kara PEG iyada oo leh qaybinta miisaanka kelli.
