Dimethyl Carbonate muhimmiyar fili ce ta musamman a masana'antar sunadarai, magani, wutan lantarki da sauran filayen. Wannan labarin zai gabatar da tsarin samarwa da kuma shiri ta kayan kwalliyar dimethyl carbonate.

1, samar da carbonate na Dimemutl

Za'a iya raba tsarin kayan Dimesthyl Carbonate zuwa nau'ikan biyu: Hanyar sunadarai da hanyar zahiri.

1) hanyar sunadarai

A synthesis na sinadarai dauki ukan carbonate na Dimethyl Carbonate shine: ch3OH + CO2 → ch3o2ch3

Methanol shine albarkatun ƙasa don Dimethyl Carbonate, da gas na carbonate shine maimaitawa. Tsarin aikin yana buƙatar mai kara kuzari.

Akwai masu conlalysts daban-daban, gami da sodium hydroxide, alli mara narkewa, da obide na uwa, da carbonate. Carbonate Ester yana da mafi kyawun sakamako na catalyttic, amma zaɓi na mai kara kuzari kuma yana buƙatar la'akari da abubuwan da dalilai kamar farashi.

Tsarin samar da katako na Dimethyl Carbonate yafi haɗa da matakai kamar tsarkakakkiyar oxidg, da sauransu a lokacin zazzabi, da kuma tsoratar da lokacin da aka dauki don inganta yawan amfanin ƙasa da Tsarkake.

2) Hanyar zahiri

Akwai manyan hanyoyin jiki guda biyu don samar da Carbonate na Dimethyl: Hanyar sha da hanyar tilastawa.

Hanyar sha tana amfani da Methanol a matsayin mai narkewa kuma yana da alaƙa da CO2 a yanayin zafi don samar da carbonate dimethyl. Hakanan za'a iya sake amfani da ruwa, kuma carbon dioxide dioxide asali ta hanyar da za'a iya sake amfani da shi, amma karancin dauki yayi jinkirin da kuma yawan kuzarin yana da yawa.

Dokar kisa tana amfani da kayan jiki na CO2 don samun hulɗa tare da Methanol a karkashin shirye-shiryen Dimesthyl Carbonate. Wannan hanyar tana da saurin sakawa, amma yana buƙatar kayan aiki mai yawa na manyan wuta kuma yana da tsada.

Hanyoyin da ke sama hanyoyi guda biyu suna da nasu arzikinsu da rashin amfanin kansu, kuma ana iya zabe dangane da aikace-aikacen aikace-aikacen da kuma abubuwan tattalin arziki.

2, Shiri Hanyar Carbonate Dimemyl

Akwai hanyoyi da yawa don shirya Dimethyl Carbonate, kuma waɗannan hanyoyin biyu ne na yau da kullun:

1) Hanyar Methanol

Wannan shine hanyar da aka saba amfani don shirya Dimethyl Carbonate. Matakan aiki na takamaiman sune kamar haka:

(1) ƙara methanol da potassium carbonate / sodium carbonate, kuma zafi don yin amsawa yayin motsa jiki;

(2) A hankali ƙara CO2, Ci gaba da motsawa, kuma sanyaya ƙasa bayan an kammala shi;

(3) Yi amfani da fusatar da rabuwa don raba cakuda kuma sami Dimethyl Carbonate.

Ya kamata a lura cewa zafin jiki, matsin lamba, lokacin da aka amsa, da kuma nau'in mai mai mai mai da ake buƙata a inganta amfanin amfanin ƙasa don inganta yawan amfanin ƙasa don inganta yawan amfanin ƙasa don inganta yawan amfanin ƙasa don inganta amfanin ƙasa da tsabta.

2) Hanyar oxygen oxygen

Baya ga hanyar methanol, hanyar oxygen oxygen ana amfani dashi don shirye-shiryen carbonate na Dimesthyl. Wannan hanyar tana da sauƙin aiki kuma suna iya samun ci gaba da samarwa.

Matakan aiki na takamaiman sune kamar haka:

(1) ƙara methanol da mai kara kuzari, zafi zuwa zazzabi yayin motsa;

(2) ƙara gas isxygen zuwa tsarin amsawa kuma yana ci gaba da motsawa;

(3) Raba, Distanya, kuma ka tsarkaka cakuda da za a samu Dimethyl Carbonate.

Ya kamata a lura cewa hanyar oxygen oxygen na buƙatar sarrafa sigogi kamar su na isar da iskar gas, da kuma yawan kayan aikin da aka gyara, don inganta amfanin ƙasa da tsabta.

Ta hanyar gabatar da wannan labarin, zamu iya koyo game da tsarin samarwa da kuma hanyoyin hanyoyin Dimethyl Carbonate. Daga tsarin kwayoyin don cikakken bayanin tsari da hanyar samarwa da hanyar samarwa, da muka samar da cikakken tsarin ilimi. Ina fatan wannan labarin na iya yada 'koyon masu karatu da bincike a cikin wannan filin.
