Dimethyl karubone CAS: 616-38-6

Dimethyl karubone (DMC), ibikoresho fatizo bya chimique bifite uburozi buke, imikorere myiza yo kurengera ibidukikije no kuyikoresha mugari, ningirakamaro hagati ya synthesis.Imiterere ya molekuline ikubiyemo amatsinda akora nka karubone, methyl na mikorerexy, kandi ifite reaction zitandukanye.Ifite ibiranga imikoreshereze yumutekano, ibyoroshye, umwanda muke hamwe nubwikorezi bworoshye mubikorwa.Dimethyl carbone ni imiti itanga icyatsi "icyatsi" kubera uburozi bwayo buke.

Inzira ya molekulari: C3H6O3;(CH3O) 2CO;CH3O-COOCH3

Uburemere bwa molekuline: 90.07

CASNo.: 616-38-6

EINECS nimero: 210-478-4

Gukoresha Kamere Ibintu byiza na molekulire idasanzwe ya DMC igena uburyo bwagutse, bushobora kuvunagurwa muburyo bukurikira:

Simbuza fosgene ikubye nka carbonylation agent.

Nubwo fosgene (Cl-CO-Cl) ifite reaction nyinshi, uburozi bwayo bukabije kandi bwangirika bwibicuruzwa bituma ihura nigitutu kinini cyibidukikije, bityo ikazavaho buhoro buhoro.DMC (CH3O-CO-OCH3) ifite reaction ya nucleophilique.Iyo itsinda rya karubone ya DMC yibasiwe na nucleophile, umurunga wa acyl-ogisijeni uracika kugirango ube karubone, kandi nibicuruzwa ni methanol.Kubwibyo, DMC irashobora gusimbuza fosgene nkigisubizo cyizewe kugirango igereranye ibikomoka kuri acide karubone, nka piside yica udukoko twa karbamate, polyakarubone, isocyanates, nibindi, aho polikarubone izaba umurima hamwe n’ibisabwa cyane kuri DMC.Biteganijwe ko muri 2005.

Simbuza dimethyl sulfate ikubye nka methylating agent.

Kubwimpamvu zisa na fosgene, dimethyl sulfate (CH3O-SO-OCH3) nayo ihura nigitutu cyo kurandura.Iyo karuboni ya methyl ya DMC yibasiwe na nucleophile, umurunga wa alkyl-ogisijeni uravunika kandi ibicuruzwa bya methylated nabyo birabyara.Byongeye kandi, umusaruro wa DMC uri hejuru kandi inzira iroroshye kuruta dimethyl sulfate.Ibyingenzi bikoreshwa harimo guhuza ibinyabuzima, imiti yimiti, imiti yica udukoko, nibindi.
