Dimethyl Carbonate nicyo kigo cyingenzi gikoreshwa cyane mu nganda za shimi, ubuvuzi, ibikoresho bya elegitoroniki nibindi bice. Iyi ngingo izamenyekanisha imikorere yumusaruro hamwe nuburyo bwo gutegura uburyo bwa Dimethyl Carbonate.

1, imikorere yumusaruro wa Dimethyl Carbonate

Inzira yumusaruro wa Dimethyl Carbonate irashobora kugabanywamo ubwoko bubiri: uburyo bwa chimique nuburyo bwumubiri.

1) Uburyo bwa chimique

Synthesis Synthesis igereranya na Dimethyl Carbonate ni: ch3oh + co2 → ch3oco2ch3

Methanol ni ibikoresho fatizo bya Dimethyl karubone, na gaze ya karubone niyo ikora. Inzira reaction isaba umusemburo.

Hariho umusemburo utandukanye, harimo sodium hydroxide, calcium oxide, okide yumuringa, na karubone. Carbonate Ester ifite ingaruka nziza za kataletique, ariko guhitamo catalyst nayo ikeneye gusuzuma ibintu nkibiciro nibidukikije.

Igikorwa cyo gutanga umusaruro wa Dimethyl karuboni ahanini kirimo intambwe nka methanol kweza, gutandukana kwa ogisijeni, kugakuramo ibipimo nkubushyuhe, ibizamini, hamwe nigihe cyo kunoza kunoza umusaruro kandi ubuziranenge.

2) Uburyo bwumubiri

Hariho uburyo bubiri bwingenzi kumubiri bwo gutanga karubone: uburyo bwo kwinjiza nuburyo bwo kwikuramo.

Uburyo bujyanye nuburyo bukoresha methanol nkumuntu nukwinjira kandi yitwara hamwe na CO2 kubushyuhe buke bwo kubyara karuboteri. Kubakwemera birashobora gukoreshwa, kandi dioxyde de carbone yakozwe na reaction irashobora kandi gukoreshwa, ariko igipimo cyimyitwarire kiratinda kandi ibiyobyabwenge biri hejuru.

Amategeko yo kwirangiza akoresha imitungo yumubiri wa CO2 kugirango ihure na methanol munsi yigitutu kinini, bityo igera kugutegura karubone ka Dimethyl. Ubu buryo bufite igipimo cyihuse, ariko bisaba ibikoresho byingufu nyinshi kandi birahenze.

Uburyo bubiri bwavuzwe haruguru bufite ibyiza byabo nibibi, kandi birashobora gutoranywa hashingiwe kubikenewe mubikorwa nubukungu.

2, Uburyo bwo Gutegura bwa Dimethyl Carbonate

Hariho uburyo butandukanye bwo gutegura karubone, kandi ibi bikurikira ni uburyo busanzwe bukoreshwa:

1) Uburyo bwa Methanol

Ubu ni uburyo bukoreshwa cyane bwo gutegura karubone ya dimethyl. Intambwe yihariye niyi ikurikira:

.

(2) Buhoro buhoro ongeraho CO2, komeza ukomere, kandi ukonje nyuma yo kubona reaction irangiye;

.

Twabibutsa ubwo bushyuhe, igitutu, umwanya wimyitwarire, kimwe n'ubwoko n'ubwato bugomba kugenzurwa mu gihe cyo kugerwaho mu buryo bwo kunoza umusaruro no kweza.

2) Uburyo bwa ogisijeni

Usibye uburyo bwa methanol, uburyo bwa ogisijeni bwa ogisijeni busanzwe bukoreshwa mugutegura karubone ka Dimethyl. Ubu buryo buroroshye gukora kandi birashobora kugera ku musaruro uhoraho.

Intambwe yihariye niyi ikurikira:

(1) Ongeraho methanol na catalyst, ubushyuhe bwo gukora ubushyuhe mugihe ubyutsa;

(2) Ongeraho gaze ya ogisijeni muri sisitemu yo kubyakirana kandi ukomeze kubyutsa;

.

Twabibutsa ko uburyo bwa ogisijeni busaba kugenzura ibipimo nkibiciro bitangwa hamwe nubushyuhe bwa gaze ya ogisijeni, ndetse nibice byibikorwa bya ogisijeni, kugirango bihuze ibice kandi ubuziranenge.

Binyuze mu ntangiriro yiyi ngingo, turashobora kwiga kubyerekeye umusaruro nuburyo bwo gutegura bwa Dimethyl karubone. Duhereye ku molekeli kugirango ibisobanuro birambuye byerekana inzira yo gusaba no gutunganya, twatanze sisitemu yuzuye kandi yukuri. Nizere ko iyi ngingo ishobora gutera imyigire y'abasomyi n'ubushakashatsi muri uru rwego.
