Methyl methacrylate

Zita reChinese: methyl methacrylate, inonzi MMA yakakosha kemikari mbishi zvinhu izvo zvinogona kuzvi-polymerize kana kuti copolymerize nemamwe mamonmer pamberi pechiedza uye kupisa kana catalysts. Inonyanya kushandiswa kugadzira polymethyl methacrylate (PMMA kwenguva pfupi) uye polyvinyl chloride impact modifiers (senge ACR, MBS). Inogona zvakare kushandiswa mukuputira, zvinonamira, machira kudhinda uye dhayi anobatsira uye mamwe minda. Iine huwandu hwakawanda hwekushandisa.

Main synthesis process yeMMA
Kune nzira dzakawanda dzekugadzira MMA, kusanganisira acetone cyanohydrin nzira (ACH nzira), isobutylene/tert-butanol oxidation nzira (C4 nzira), ethylene nzira (C2 nzira), methanol-methyl acetate nzira (C1 nzira), nezvimwewo, maererano kune yavo The raw material kabhoni nhamba yakasiyana uye inogona kukamurwa kuva C1 nzira, C2 nzira, C3 nzira uye C4 nzira.
Kubva pakuona kwepasirese, iyo inonyanya kushandiswa kugadzira maitiro ndiyo nzira yeACH. Iyi tekinoroji tekinoroji yakakura, yakagadzikana uye iri nyore, inoverengera inosvika 61.6% yekugadzirwa kwenyika, kunyanya kuNorth America, Western Europe, neChina; ichiteverwa neC4 nzira, yakagadziridzwa neJapan Shokubai Chemical Yakagadzirwa neIndustrial Corporation neMitsubishi Rayon Company muna 1982, tekinoroji yave mberi, midziyo haina chepfu uye haina kukuvadza, kune zvishoma zvigadzirwa uye mutengo wakaderera, accounting. kweinenge 30.5% yekugadzirwa kwenyika.

Chemical Properties

Mvura isina ruvara, inoputika nyore. Soluble mune zvakasiyana-siyana organic solvents akadai ethanol, ether, acetone, etc. Zvishoma soluble mu ethylene glycol nemvura.

Kushandisa:

Inonyanya kushandiswa semonomer yegirazi regirazi, uye rinoshandiswawo kugadzira mamwe mapurasitiki, machira, nezvimwe.
