Dimethyl carbonate fili ne na kwayoyin halitta tare da dabarar sinadarai C3H6O3.Shi ɗanyen sinadari ne mai ƙarancin guba, kyawawan kaddarorin kariyar muhalli da fa'idar amfani.Yana da mahimmancin haɗin gwiwar kwayoyin halitta.Yana da halaye na ƙarancin ƙazanta da sauƙin sufuri.Bayyanar dimethyl carbonate ruwa ne mara launi tare da ƙanshin ƙanshi;nauyin kwayoyin halitta shine 90.078, wanda ba zai iya narkewa a cikin ruwa ba, mai sauƙi a cikin yawancin kaushi na kwayoyin halitta, rashin daidaituwa a cikin acid da tushe.
Amfani da dimethyl carbonate
(1) Sauya phosgene a matsayin wakili na carbonylating
DMC yana da irin wannan cibiyar amsawar nucleophilic.Lokacin da ƙungiyar carbonyl ta DMC ta kai hari ta hanyar nucleophile, haɗin acyl-oxygen ya karye don samar da fili na carbonyl, kuma samfurin shine methanol.Saboda haka, DMC na iya maye gurbin phosgene a matsayin amintaccen reagent don haɗa abubuwan da suka samo asali na carbonic acid., Polycarbonate zai zama yanki tare da mafi yawan bukatar DMC.
(2) Sauya dimethyl sulfate a matsayin wakili na methylating
Lokacin da methyl carbon na DMC ya kai hari ta hanyar nucleophile, haɗin alkyl-oxygen ya karye, kuma samfurin methylated kuma ana samar da shi, kuma yawan amsawar DMC ya fi na dimethyl sulfate, kuma tsari ya fi sauƙi.Babban amfani sun haɗa da tsaka-tsakin kwayoyin halitta na roba, samfuran magunguna, samfuran magungunan kashe qwari, da sauransu.
(3)mafi ƙarancin guba
DMC yana da kyau kwarai solubility, kunkuntar narkewa da tafasar batu jeri, babban surface tashin hankali, low danko, low dielectric akai, high evaporation zafin jiki da sauri evaporation kudi, don haka shi za a iya amfani da a matsayin low-mai guba sauran ƙarfi ga coatings Masana'antu da Pharmaceutical masana'antu.DMC ba wai kawai ƙananan ƙwayar cuta ba ne, amma har ma yana da halaye na babban ma'anar walƙiya, ƙananan tururi da ƙananan fashewa a cikin iska, don haka yana da sauran ƙarfi mai kore wanda ya haɗu da tsabta da aminci.
(4)Maganin man fetur
DMC yana da kaddarorin babban abun ciki na oxygen (har zuwa 53% abun ciki na oxygen a cikin kwayar halitta), kyakkyawan sakamako mai haɓaka octane, babu rabuwar lokaci, ƙarancin guba da saurin biodegradability, kuma yana rage adadin hydrocarbons, carbon monoxide da formaldehyde a cikin sharar mota. .Bugu da kari, yana kuma shawo kan gazawar abubuwan da ake hada man fetur na gama-gari wadanda ke saurin narkewa a cikin ruwa da gurbata tushen ruwan karkashin kasa.Saboda haka, DMC zai zama ɗaya daga cikin abubuwan da za a iya ƙara man fetur don maye gurbin MTBE.
