Dimethyl carbone ni uruganda rukomeye rukoreshwa cyane mu nganda z’imiti, ubuvuzi, ibikoresho bya elegitoroniki n’izindi nzego. Iyi ngingo izerekana uburyo bwo gukora nuburyo bwo gutegura karubone ya dimethyl.

1 process Uburyo bwo gukora karubone ya dimethyl

Igikorwa cyo gukora karubone ya dimethyl irashobora kugabanywamo ubwoko bubiri: uburyo bwa chimique nuburyo bwumubiri.

1 method Uburyo bwa shimi

Imiti ya synthesis reaction ya dimethyl karubone ni: CH3OH + CO2 → CH3OCO2CH3

Methanol ni ibikoresho fatizo bya karubone ya dimethyl, na gaze ya karubone niyo ikora. Inzira yo kubyitwaramo isaba umusemburo.

Hariho ibintu bitandukanye, harimo sodium hydroxide, oxyde ya calcium, okiside y'umuringa, na karubone. Carbone ester ifite ingaruka nziza za catalitiki, ariko guhitamo catalizator nayo igomba gutekereza kubintu nkigiciro nibidukikije.

Igikorwa cyo gukora karubone ya dimethyl gikubiyemo cyane cyane intambwe nko kweza methanol, okisijeni ya ogisijeni, gushyushya ubushyuhe, gutandukana / gutandukanya, n'ibindi. ubuziranenge.

2 method Uburyo bw'umubiri

Hariho uburyo bubiri bwibanze bwo gukora dimethyl karubone: uburyo bwo kwinjiza nuburyo bwo kwikuramo.

Uburyo bwo kwinjiza bukoresha methanol nk'iyinjiza kandi igakorana na CO2 ku bushyuhe buke kugirango itange karubone ya dimethyl. Ibyinjira bishobora kongera gukoreshwa, kandi karuboni ya dioxyde de carbone iterwa na reaction nayo irashobora gukoreshwa, ariko igipimo cyibisubizo kiratinda kandi gukoresha ingufu ni byinshi.

Amategeko yo guhonyora akoresha ibintu bifatika bya CO2 kugirango ahure na methanol kumuvuduko mwinshi, bityo bigere ku itegurwa rya karubone ya dimethyl. Ubu buryo bufite umuvuduko wihuse, ariko busaba ibikoresho byo guhunika imbaraga nyinshi kandi birahenze.

Ubu buryo bubiri buvuzwe haruguru bufite inyungu n’ibibi, kandi burashobora gutoranywa ukurikije ibikenewe hamwe nubukungu.

2 method Uburyo bwo gutegura karubone ya dimethyl

Hariho uburyo butandukanye bwo gutegura karubone ya dimethyl, kandi ibikurikira nuburyo bubiri bukoreshwa:

1 method Uburyo bwa Methanol

Ubu ni bwo buryo bukoreshwa cyane mugutegura karubone ya dimethyl. Intambwe yihariye yo gukora niyi ikurikira:

(1) Ongeramo methanol na potasiyumu karubone / sodium karubone, nubushyuhe kubushyuhe bwa reaction mugihe ukurura;

(2) Buhoro buhoro ongeramo CO2, komeza ukangure, hanyuma ukonje nyuma yuko reaction irangiye;

(3) Koresha umuyoboro wo gutandukanya gutandukanya imvange no kubona karubone ya dimethyl.

Twabibutsa ko ubushyuhe, umuvuduko, igihe cyo kubyitwaramo, kimwe nubwoko nubunini bwa catalizator bigomba kugenzurwa mugihe cyibikorwa kugirango byongere umusaruro nubuziranenge.

2 method Uburyo bwa okisijeni

Usibye uburyo bwa methanol, uburyo bwa okisijeni ya ogisijeni nabwo bukoreshwa mugutegura karubone ya dimethyl. Ubu buryo bworoshye gukora kandi burashobora kugera kumusaruro uhoraho.

Intambwe yihariye yo gukora niyi ikurikira:

(1) Ongeramo methanol na catalizator, ubushyuhe kubushyuhe bwa reaction mugihe ukurura;

(2) Ongeramo gaze ya ogisijeni muri sisitemu yo kubyitwaramo hanyuma ukomeze kubyutsa;

(3) Tandukanya, ushishimure, kandi usukure ivangwa rya reaction kugirango ubone karubone ya dimethyl.

Twabibutsa ko uburyo bwa okisijeni ya ogisijeni busaba kugenzura ibipimo nkigipimo cyogutangwa nubushyuhe bwa gaze ya ogisijeni, hamwe nigipimo cyibigize reaction, kugirango umusaruro wiyongere.

Binyuze mu gutangiza iyi ngingo, turashobora kwiga kubyerekeye uburyo bwo kubyaza umusaruro nuburyo bwo gutegura karubone ya dimethyl. Kuva kumiterere ya molekulari kugeza ibisobanuro birambuye byuburyo bwo kubyitwaramo nuburyo bwo gutanga umusaruro, twatanze sisitemu yubumenyi yuzuye kandi yuzuye. Nizere ko iyi ngingo ishobora gutera abasomyi imyigire nubushakashatsi muriki gice.
