Ipamba itunganyijwe—ifungura—itunganya—ihindura—ihindura—igabanya—ikuraho—ikuraho, ihumura—itunganya—ipfunyika—irangiza ipamba: ipamba itunganijwe irafungurwa kugira ngo ikureho icyuma, hanyuma ikarangizwa. Ipamba itunganijwe itunganijwe iba mu buryo bw'ifu, kandi ingano y'uduce twayo ni mesh 80 kandi uburyo bwo kuyikwirakwiza ni 100%. Bitabaye ibyo, biroroshye kuyiteranya mu gihe cyo kuyikora no kugabanya ubushobozi bwo kuyihindura.
Alkalization: Shyiramo ipamba itunganyijwe ifu nyuma yo kuyifungura mu kintu kidakora neza, hanyuma uyishyiremo alkali n'amazi yoroshye kugira ngo wongere urukuta rw'ipamba itunganyijwe, ibyo bikaba byorohereza kwinjira mu ngirabuzimafatizo zitanga etherifying, kandi binoze uburyo etherification ikorwa. Alkali ikoreshwa muri alkali ni hydroxide y'icyuma cyangwa organic base. Ingano ya alkali yongewemo (ukurikije uburemere, kimwe kiri hepfo) ni inshuro 0.1-0.6 z'ipamba itunganijwe neza, kandi ingano y'amazi yoroshye ni inshuro 0.3-1.0 z'ipamba itunganijwe neza; solvent itagira ingufu ni uruvange rwa alcool na hydrocarbon, kandi ingano y'solvent itagira ingufu yongewemo ni ipamba itunganijwe neza. Inshuro 7-15: solvent itagira ingufu ishobora kandi kuba alcool ifite atome 3-5 za karuboni (nka alcool, propanol), acetone. Ishobora kandi kuba aliphatic hydrocarbons na aromatic hydrocarbons; ubushyuhe bugomba kugenzurwa muri 0-35°C mu gihe cyo kuyitunganya; igihe cyo kuyitunganya ni isaha 1. Guhindura ubushyuhe n'igihe bishobora kugenwa hakurikijwe ibisabwa n'ibikoresho n'ibicuruzwa.
Etherification: Nyuma yo gutunganya alkalize, mu gihe cy'umwuka uvamo umwuka, etherification ikorwa hongerwamo etherification, kandi etherification ni propylene oxide. Kugira ngo ugabanye ikoreshwa ry'etherification, mu gikorwa cyo etherification, etherification yongerwamo inshuro ebyiri, ingano y'inyongera ya mbere ni inshuro 1-3.5 z'ipamba ryatunganyijwe, kandi ingano y'inyongera ebyiri ni inshuro 1.5-4 z'ipamba ryatunganyijwe. Nyuma yo kongeramo etherification ku nshuro ya mbere, kangura ku bushyuhe bwa ≤30°C mu gihe cy'iminota 45-90, hanyuma ushyushye kugeza kuri 50-100°C kugira ngo etherification ikore, igihe ni amasaha 1-5, hanyuma ukonje kugeza kuri ≤30°C. Ongeramo etherified Jing ku nshuro ya kabiri hanyuma uvange, igihe cyo kuvanga ni iminota 30-120, hanyuma ushyushye kugeza kuri ? ? ? Kora etherification, igihe ni amasaha 1-4, muri iki gihe, ipamba itunganyijwe n'ikintu gitanga etherification bikora neza kugira ngo bikore H-HPC.
Gusya no gupakira: umusaruro wumye w'ubu buvumbuzi urasya kandi ugasya. Ingano y'uduce tw'umusaruro wasya kandi ugasya w'ubu buvumbuzi ni mesh 40 naho uburyo bwo kohereza ni 10096, cyangwa ukurikije ibyo umukoresha akeneye. Hanyuma upake uwukure mu ruganda.
