Dimethyl carbonate yakakosha organic yakawedzera kushandiswa mumakemikari indasitiri, mushonga, magetsi uye mamwe minda. Chinyorwa ichi chinosvitsa maitiro ekugadzira uye nzira yekugadzirira yeDimethyl carbonate.

1, kugadzirwa kwemaitiro e dimethyl carbonate

Iyo yekugadzira maitiro eDimethyl carbonate inogona kukamurwa kuita marudzi maviri: nzira yemakemikari uye nzira yemuviri.

1) nzira yemakemikari

Iyo yemakemikari synthesis reaction equation yeDimethyl Carbonate ndeye: C3OOOH + CO2 → C3OCO2CH3CH3

Methanol ndiyo yakavezwa yezvinhu yeDimethyl carbonate, uye gasi carbonate ndiyo yakaitika. Maitiro ekuita anoda chirahwe.

Kune akasiyana ekutengesa, kusanganisira sodium hydroxide, calcium oxide, mhangura oxide, uye carbonate. Carbonate ester ine yakanyanya kuwanda maitiro, asi kusarudzwa kwekutengesa zvakare kunodawo kufunga nezvezvinhu zvakadai semutengo uye nharaunda.

Maitiro ekugadzira kweDimethyl kabhoni anonyanya kusanganisira matanho akadai seye methanol kunatswa, kuparadzaniswa, kusimbisa, kumanikidzwa, uye kuita nguva inodiwa kuti uvandudze goho uye kuchena.

2) nzira yemuviri

Pane nzira mbiri huru dzepanyama dzekubereka Dimethyl Carbonate: Kupfuura nzira uye nzira yekumanikidza.

Nzira yekunyora inoshandisa methanol seyakawana uye inobata neCO2 kuderera tembiricha kugadzira dimethyl carbonate. Iyo inobata inogona kushandiswazve, uye kabhoni dioxide inogadzirwa nekuita kunogoneka zvakare, asi chiyero chechiitiko chinononoka uye kushandiswa kwesimba kwakakwira.

Mutemo wekumanikidza unoshandisa zvivakwa zveCO2 kuti ubatane naMethanol pasi pekumanikidzwa kwepamusoro, nekudaro uchiita gadziriro yeDimethyl carbonate. Iyi nzira ine chiyero chekutsanya, asi chinoda yakakwira-simba kumisikidza michina uye inodhura.

Nzira dziri pamusoro apa dzine zvadzo zvakanakira uye zvakashata, uye zvinogona kusarudzwa zvichibva pane zvinodikanwa zvekushandisa uye zvinhu zvehupfumi.

2, nzira yekugadzirira yeDimethyl carbonate

Kune nzira dzakasiyana-siyana dzekugadzirira dimethyl carbonate, uye zvinotevera zvinhu zviviri zvinowanzo shandiswa zvinoshandiswa:

1) methanol nzira

Iyi ndiyo nzira inowanzo shandiswa yekugadzirira dimethyl carbonate. Matanho Ekuvhenekerwa ari kuita seanotevera:

.

(2) zvishoma nezvishoma wedzera Co2, ramba uchimutsa, uye kutonhorera pasi mushure mekuita kwacho kwapera;

.

Inofanirwa kucherechedzwa kuti tembiricha, kumanikidzwa, kuita nguva, pamwe nerudzi uye huwandu hwechirwere chinoda kudzorwa panguva yekuita kuti uvandudze goho uye kuchena.

2) Oxygen oxidation nzira

Pamusoro peiyo methanol nzira, oksijeni oxidation nzira inowanzoitwa yekugadzirira yeDimethyl carbonate. Iyi nzira iri nyore kushanda uye inogona kuwana kuenderera mberi kugadzirwa.

Matanho Ekuvhenekerwa ari kuita seanotevera:

.

(2) Wedzera okisijeni gasi kune reaction system uye ramba uchimutsa;

.

Izvo zvinofanirwa kucherechedzwa kuti iyo oxygen oxidation nzira inoda kudzora parmeter yakadai sekugovera chiyero uye kudzikisira tembiricha gasi, pamwe nehuwandu hwezvinhu zvegadzirisirwo, kugadzirisa gohwo uye kuchena.

Kuburikidza nekutanga kwenyaya ino, tinogona kudzidza nezve maitiro ekugadzira uye nzira dzekugadzirira dzeDimethyl carbonate. Kubva pamanyorerwo gadziriso kutsanangurwa kwetsananguro yetsananguro uye nzira yekugadzira, isu takapa ruzivo rwakakwana uye rwakakwana ruzivo. Ndinovimba chinyorwa ichi chinogona kukurudzira kudzidza kuverenga nekutsvaga mumunda uyu.
