Sida dareeraha cagaarka ah, methyl acetate waa laga dhaafay xaddidaadda waxaana loo isticmaalaa sida dareeraha organic ee wax soo saarka ester, daahan, khad, rinji, dhejisyada iyo maqaarka;oo u dhaqmo sida wakiilka xumbo xumbada poliurethane, dheeraad ah, waxa kale oo loo isticmaali karaa sida saarista saliidda iyo dufan ee wax soo saarka ee maqaarka macmal ah, udgoonka, iyo iwm. waa 210ktpa.

Waa maxay Methyl Acetate?
Heerkulka caadiga ah, methyl acetate waa 25 boqolkiiba ku milmay biyaha.Waxay leedahay milmayn aad u wayn oo biyaha ku jira heerkul sare.Marka ay joogaan saldhigyada aqueous ama acids, methyl acetate waa mid aan degganayn.Iyada oo dhibicda -10 ° C iyo qiimaha ololka ee 3, aad bay u gubanaysaa.Methyl acetate waa dareere yar oo sun ah oo inta badan laga helo xabagta iyo kuwa ciddiyaha nadiifiya.Tufaaxa, canabka, iyo muuska ayaa ka mid ah miraha ay ku jiraan methyl acetate.
Isticmaalka Warshadaha
Dareen-celinta carbonylation ee leh methyl acetate si loo dhaliyo anhydride acetic waxaa loo isticmaalaa warshadaha.Waxa kale oo loo isticmaalaa sida dareere ee rinjiga, xabagta, ciddiyaha cidiyaha, iyo kuwa wax lagu qoro, iyo sidoo kale saliidaha, dhexdhexaadiyeyaasha, iyo qalabka wax lagu farsameeyo.
Methyl acetate waxaa sidoo kale loo isticmaalaa sidii dhexdhexaad kiimikaad ah ee soo saarista xabagta cellulose iyo cadarka, iyo sidoo kale isku dhafka chlorophacinone, diphacinone, fenfluramine, o-methoxy phenylacetone, p-methoxy phenylacetone, methyl cinnamate, methyl cyanodocetate, methyl phenylacetate. .
Methyl acetate waxaa loo isticmaalaa sida wakiilka dhadhanka ee cuntada lagu daro rum, brandy, iyo whisky, iyo sidoo kale xabagta, alaabta nadiifinta, daryeelka shakhsi ahaaneed, iyo alaabta la isku qurxiyo, saliidaha, rinji si degdeg ah u qallajiya sida lacquers, dahaarka baabuurta, dahaarka alaabta guriga. , dahaarka warshadaha (bar karkaraya hoose), khadadka, resins, saliidda, iyo alaabta elektarooniga ah.Rinjiga, dahaarka, waxyaalaha la isku qurxiyo, dharka, iyo waaxaha baabuurta ayaa ah suuqa ugu dambeeya ee walaxdan.
Carbonylation waa mid ka mid ah hababka loo isticmaalo warshadaha.Qaybaha kaarboon moono-oksaydh ayaa la isugu keenay falcelintan.Methanol waxaa lagu gubay acetic acid iyadoo ay jirto sulfuric acid si loo sameeyo methyl acetate.
Esterification of methanol iyo acetic acid joogitaanka asiidh xoog leh waa hab kale oo isku dhafan.Habkani waxa kale oo uu ka shaqeeyaa isticmaalka sulfuric acid kaabayaal ahaan.
