Synthesis Reaction Ntawm Polyether Polyols

Pretreatment ntawm raw cov ntaub ntawv - feem ntau, tus pib thiab catalyst yog ua ntej sib tov los tsim cov hlau hydrocarbon oxides, uas yog ces nqus dej dehydrated thiab ntxiv rau lub reactor.
Lub nplhaib qhib polymerization cov tshuaj tiv thaiv - Cov tshuaj tiv thaiv no yog exothermic thiab cov tshuaj tiv thaiv tshav kub yuav tsum raug tshem tawm raws sijhawm; Txhawm rau tiv thaiv oxidation tshwm sim, cov roj nitrogen qhuav yuav tsum tau qhia ua ntej cov tshuaj tiv thaiv.
Cov txheej txheem tom qab ua tiav feem ntau suav nrog cov khoom xws li nruab nrab, adsorption, lub cev qhuav dej, pom, distillation, thiab lwm yam.
