Polyethylene Glycol (PEG) Synthesis Solution

Zochita za polymerization zimayika zofunikira kwambiri pakutengera kutentha komanso kusakanikirana kwa ma reactor. Zolakwa za miyambo batch reactors muzinthu izi zakhala chimodzi mwazomwe zimalepheretsa kukwaniritsa ma polima ochita bwino kwambiri. Komano, ma microchannel reactors amatha kuwongolera kuyenda kwapang'onopang'ono kwa ma multiphase, kupititsa patsogolo kusanganikirana, kusamutsa misa, ndi njira zosinthira kutentha panthawi ya polymerization. Iwo mosamalitsa kulamulira anachita nthawi ndi kukwaniritsa modular msonkhano wa mayunitsi anachita, potero mwangwiro kugonjetsa botolo izi. Poyerekeza ndi miyambo mtanda riyakitala, zinthu izi kupereka microchannel reactors kwambiri ubwino kulamulira polima maselo kulemera kugawa, kufewetsa zinthu anachita, kuwongolera anachita selectivity, ndi malamulo polima maselo ndi macroscopic morphology.

Polyethylene glycol (PEG) ndi polima wosungunuka m'madzi wopangidwa kuchokera ku ethylene oxide ndi ethylene glycol.Molekyulu ya PEG ili ndi magulu ambiri a ethoxy, omwe amatha kupanga ma hydrogen zomangira ndi madzi ndikusakaniza ndi madzi mu chiŵerengero chilichonse. PEG ndi yofatsa muzotsatira zake, imayambitsa zovuta zochepa, ndipo imakhala ndi chiyembekezo chachikulu chamsika ngati chothandizira pazamankhwala. Pakadali pano, kupanga kwapang'onopang'ono kwapang'onopang'ono PEG nthawi zambiri kumagwiritsa ntchito zida zachikhalidwe zamagulu polima. Ngakhale njirayi imatha kupanga PEG yokhala ndi index ya dispersity pansi pa 1.05, mankhwalawa akadali osakanikirana ndi zolemetsa zosiyanasiyana. Ngakhale pansi mkulu-chiyero zopangira ndi stringent anhydrous ndondomeko zinthu, polymerization miyambo mtanda reactors sangathe kukwaniritsa limodzi kugawa msomali. Ndi ma microchannel reactor okha omwe amatha kuphatikizira PEG ndi gawo limodzi lolemera la maselo.
