Dimethyl karubone ni iki?

Dimethyl karubone ni ifumbire mvaruganda hamwe na formula ya chimique C3H6O3.Nibikoresho fatizo byimiti bifite uburozi buke, ibyiza byo kurengera ibidukikije nuburyo butandukanye bwo gukoresha.Nibintu byingenzi bihinduranya hagati.Ifite ibiranga umwanda muke no gutwara byoroshye.Kugaragara kwa karubone ya dimethyl ni ibara ritagira ibara rifite impumuro nziza;uburemere bwa molekile ni 90.078, budashonga mumazi, ntibishobora kuboneka mumashanyarazi menshi, ntibishobora kuboneka muri acide na base.

Gukoresha karubone ya dimethyl

(1) Gusimbuza fosgene nkibikoresho bya karubone
DMC ifite ikigo gisa na nucleophilique.Iyo itsinda rya karubone ya DMC yibasiwe na nucleophile, umugozi wa acyl-ogisijeni wacitse kugirango ube karuboni, kandi ibikomoka kuri methanol.Kubwibyo, DMC irashobora gusimbuza fosgene nka reagent itekanye kugirango ikomatanye ibikomoka kuri aside ya karubone., Polyakarubone izaba agace gakenewe cyane DMC.

(2) Gusimbuza dimethyl sulfate nkibikoresho bya methylating
Iyo karuboni ya methyl ya DMC yibasiwe na nucleophile, umurunga wa alkyl-ogisijeni uravunika, kandi na methylated product nayo ikabyara umusaruro, kandi umusaruro wa DMC ukaba mwinshi ugereranije na sulfate ya dimethyl, kandi inzira iroroshye.Imikoreshereze nyamukuru ikubiyemo intungamubiri ngengabihe, ibikomoka ku miti, imiti yica udukoko, nibindi.

(3) uburozi buke
DMC ifite imbaraga zidasanzwe, gushonga no gutekera ahantu harehare, hejuru yubushyuhe bunini, ubukonje buke, guhora dielectric ihoraho, ubushyuhe bwinshi bwo guhumeka hamwe nigipimo cyuka cyihuta, bityo irashobora gukoreshwa nkumuti muke wuburozi buke bwo gutwikira inganda ninganda zikora imiti.DMC ntabwo iri hasi yuburozi gusa, ahubwo ifite n'ibiranga flash point yo hejuru, umuvuduko ukabije wumuyaga hamwe no kugabanuka guturika mukirere, bityo rero ni icyatsi kibisi gihuza isuku numutekano.

(4) Inyongera ya lisansi
DMC ifite imiterere ya ogisijeni nyinshi (igera kuri 53% ya ogisijeni iri muri molekile), ingaruka nziza yo kongera octane, nta gutandukanya icyiciro, uburozi buke na biodegradabilite yihuta, kandi igabanya urugero rwa hydrocarbone, monoxide carbone na formaldehyde mumashanyarazi .Byongeye kandi, inesha ibitagenda neza byongeweho lisansi isanzwe ibora byoroshye mumazi kandi ikanduza amasoko yubutaka.Kubwibyo, DMC izahinduka kimwe mubishobora kongera lisansi yo gusimbuza MTBE.

Kubika no Gutwara Carbonate ya Dimethyl

Kwirinda Ububiko:Irashya, kandi umwuka wacyo uvanze numwuka, ushobora gukora imvange iturika.Ubibike mububiko bukonje, bwumye, kandi buhumeka neza mububiko budashya.Irinde umuriro nubushyuhe.Ubushyuhe bw'isomero ntibugomba kurenga 37 ℃.Komeza ibikoresho bifunze cyane.Igomba kubikwa ukwayo na okiside, kugabanya ibintu, acide, nibindi, kandi ntibigomba kuvangwa.Koresha amatara adashobora guturika no guhumeka.Kubuza gukoresha ibikoresho bya mashini nibikoresho bikunda kugaragara.Ahantu ho guhunika hagomba kuba hafite ibikoresho byihutirwa byihutirwa nibikoresho byabigenewe, bigomba kubikwa mububiko bukonje, bwumye kandi buhumeka neza butabikwa.

Uburyo bwo gutwara abantu:Gupakira Ibimenyetso Byakongejwe Amazi yo gupakira Uburyo busanzwe bwimbaho ​​yimbaho ​​hanze ampules;Agasanduku gasanzwe k'ibiti hanze amacupa yikirahure hejuru, amacupa yikirahure yuzuye ibyuma, amacupa ya pulasitike cyangwa ibyuma bya bombo (amabati) Uburyo bwo gutwara abantu Ibinyabiziga bitwara abantu Ibikoresho byo kuzimya umuriro nibikoresho byihutirwa byihutirwa bigomba kuba bifite ubwoko butandukanye nubwinshi.
