Nigute sodium carboxymethylcellselllcellse?

Gukoresha selile nkibikoresho fatizo, CMC-NA byateguwe nuburyo bumwe. Iya mbere nuburyo bwa alkalisation ya selile. Ubugari bwa selile hamwe na sodium hydroxide kugirango bishobore kubyara selile alKali, hanyuma selile ya selile ya alkali yitwara acide ya chloroaceti kuri cmc-na, zitwa gutora.

Gahunda yimyitwarire igomba kuba alkaline. Iyi nzira ni iy Williamson Synthesis Sympesis. Uburyo bwo gukora reaction ni usimburwa nocleoophilic. Sisitemu yo kwitwara ni alkaline, kandi iherekejwe nimikorere imwe imbere y'amazi, nka sodium glycolate, aside ya glycolate, acide ya glycolic nibindi bicuruzwa. Bitewe no kubaho kw'ibitabo byo ku mpande, gukoresha umukozi wa Alkali na Adrisimic biziyongera, bityo bikagabanya imikorere ihindagurika; Icyarimwe, sodium glycolate, acide glycolic hamwe numwanda wumunyu birashobora guterwa muruhande rwibintu, bigatera ubuziranenge nibikorwa byo kugabanya ibicuruzwa. Kugirango uhagarike ibisubizo byumurongo, birakenewe gusa gukoresha alkali, gusa ahubwo binagenzura ingano ya sisitemu y'amazi, kwibanda kuri alkali nuburyo bwo kubyutsa alkali hagamijwe guhakana alkalisation. Mugihe kimwe, ibisabwa nibicuruzwa kuri viscosity nurwego rwo gusimbuza bigomba gusuzumwa, kandi umuvuduko ukabije nubushyuhe bigomba gufatwa nkibyo. Kugenzura nibindi bintu, ongera igipimo cyo guta agaciro, kandi kibuza ibintu bibaye inyuma.

Dukurikije itangazamakuru ritandukanye, umusaruro w'inganda wa CMC-NA urashobora kugabanywa mu byiciro bibiri: uburyo bushingiye ku mazi n'uburyo bushingiye ku gitsina. Uburyo bukoresha amazi nkuko reaction yitwa uburyo bwo hagati bwamazi, bukoreshwa mugutanga igipimo cya alkaline hamwe na cmc-n. Uburyo bwo gukoresha Solvent nkuko reaction yitwa uburyo bwo gukemura, bukwiriye gukora imisaruro ya CMC-NE. Ibi bisubizo byombi bikorwa mu kagaburibyo, bikaba byarateganijwe kandi kuri ubu ni uburyo nyamukuru bwo gukora cmc-na.

WAter Uburyo bwo Hagati:

Uburyo butunganya amazi ni gahunda yo gutanga umusaruro wa mbere, igomba kubyitwaramo ya Alkali na Addeint yabuze mu bihe bya Alkali by'ubuntu. Mugihe cya alkalisation no guhinduka, nta buryo busanzwe muri sisitemu. Ibisabwa ibikoresho byubwoko bwibitangazamakuru byamazi biraryoroshye, hamwe nishoramari rito nigiciro gito. Ibibi ni ukubura umubare munini wamazi, ubushyuhe buterwa nubushyuhe, bwihutisha umuvuduko wibintu, biganisha ku buryo buke, kandi bwiza bwibicuruzwa. Uburyo bukoreshwa mugutegura ibicuruzwa bya CMC-NEG-NEG, nkibikoresho byabitswe, abakozi bambaye imyenda nibindi nkibyo.

SUburyo bwa Olven:

Uburyo bwo gukemura nabwo bwitwa uburyo bwo gukemura kama, kandi ikintu nyamukuru ni uko ibisubizo bya alkalisation no gukurikiranwa muburyo bwa organic nkuko reaction igabanya (diluennt). Ukurikije ingano ya dilunt ya reactive, igabanijwemo uburyo bwo guteka hamwe nuburyo butunguranye. Uburyo bworoshye ni kimwe nuburyo bwo gukora bwuburyo bwamazi, kandi bugizwe nibyiciro bibiri byo alkana no guhagarara, ariko imyifatire yimyitwarire yizi ngingo zombi iratandukanye. Uburyo bworoshye buzigama inzira yo gushiramo Alkali, gukanda, guhonyora, gusaza, no kubyahumanya muburyo bwamazi, kandi alkalisation hamwe nubuzima nibikorwa byose. Ingaruka ni uko ubushyuhe bushingiye ku bushyuhe ari abakene, kandi umwanya usabwa nibiciro ni mwinshi. Birumvikana, kugirango umusaruro wibikoresho bitandukanye, birakenewe ko hagabana neza ubushyuhe bwa sisitemu, igihe cyo kugaburira, nibindi rero bitegurwa ubuziranenge kandi imikorere myiza.
