Nsoroidiyo: Alkali Cellulose bụ polymer polymer nwere otu ụdị Hydroxy atọ na mgbanaka ọ bụla. Otu kachasị na-arụ ọrụ iji mepụta hydroxyethythythythythythythythythyth cellulose. Sook ahụ owu na-egbu egbu ma ọ bụ a nụchara anụ ahụ na 30% mmiri alkali, ma were ya maka ịpị mgbe ọkara elekere gasịrị. Pia ruo mgbe ọdịnaya mmiri alkaline ruru 1: 2.8, wee gwepịa ya. A na-etinye ya na ihe na-egbu egbu, kaa ya, vutumed, ma jupụta nitrogen. Chemicalbook dere ugboro ugboro kewara ma jupụta na nitrogen iji dochie ikuku niile. Press in precooled ethylene oxide liquid, pass cooling water into the reactor jacket, and control the reaction temperature to about 25 ℃ for 2h to obtain a crude hydroxyethyl cellulose product. A na-eji ọgwụ acid na-asacha ngwaahịa n 'ị alwarị, acid acid na ph 4-6, na ijikọ glyoxal maka ịka nká. Then wash with water, centrifuge, dehydrate, dry, and grind to obtain hydroxyethyl cellulose.
