Polyethylene Glycol (PEG) Synthesis Solution

Kuita kwepolymerization kunoisa zvikumbiro zvakakwirira pakuita kwekupisa kwekushisa uye kusanganisa kugona kwemaactor. Iko kukanganisa kwechinyakare batch reactors mune izvi zvinhu zvave chimwe chezvipingamupinyi mukuwana yakakwirira-inoshanda mapolymers. Kune rimwe divi, microchannel reactors inogona kugonesa inodzoreka multiphase micro-scale kuyerera, kuwedzera musanganiswa, kutakura hukuru, uye kupisa kwekutamisa maitiro panguva yepolymerization maitiro. Ivo vanonyatso kudzora nguva yekuita uye vanowana modular gungano rekuita zvikamu, nekudaro vachikunda zvakakwana ichi bhodhoro. Zvichienzaniswa neyakajairwa batch reactor, aya maficha anopa microchannel mabhenefiti akakosha mukudzora polymer molecular uremu kugovera, kurerutsa maitiro ekuita, kuvandudza maitiro ekusarudza, uye kudzora mapolymer molecular chimiro uye macroscopic morphology.

Polyethylene glycol (PEG) inonzi polymer yakanyungudika nemvura yakasanganiswa kubva kuethylene oxide uye ethylene glycol.Molekuru yePEG ine nhamba huru yemapoka ethoxy, anogona kuumba hydrogen zvisungo nemvura uye kusanganiswa nemvura mune chero chiyero. PEG yakapfava mumhedzisiro yayo, inokonzeresa maitiro mashoma, uye inobata tarisiro yemusika wakakura semubatsiri wemishonga. Parizvino, maindasitiri-chiyero kugadzirwa kweyakatetepa-kugovera PEG kazhinji inoshandisa yechinyakare batch reactor yekupolymerization. Nepo maitiro aya achigona kuburitsa PEG ine disperity index pazasi 1.05, chigadzirwa ichi chichiri musanganiswa weakasiyana ma molecular weight. Kunyangwe pasi peyakanyanya-kuchena mbishi zvinhu uye stringent anhydrous process mamiriro, polymerization mune yechinyakare batch reactor haigone kuwana imwechete-kugovera PEG. Chete microchannel reactor inogona kubatanidza PEG neiyo imwe chete molecular uremu kugovera.
