Amayi, omwe amadziwika kuti methyl methacrytete, ndi chinthu chofunikira chopangira polymethyl methacrylate (PMMA), omwe amadziwikanso kuti acrylic. Ndi kusintha kwa kusintha kwa makampani a PMMA, kukula kwa unyolo wa mma fakitale wakankhidwira kumbuyo. Malinga ndi kafukufukuyu, pali njira zitatu zopangira za MACOTONE CANOHEDRIN (Njira Yabwino), Ethynee Carbonulation Njira ya Irobutylene, Njira ya ISobutyylene). Pakadali pano, njira ya ac ndi c4 imagwiritsidwa ntchito makamaka pamabizinesi opanga Chitchaina, ndipo palibe gawo lopanga magetsi a Ethylene.

Kuphunzira kwathu kwa Mmaunity undresyed njira zopanga zokhala pamwambazi ndi zotsika kwambiri za pmma motsatana.

Chithunzi 1 Tchati Choyenda cha Mma Faniry ndi njira zosiyana (zojambulajambula: Makampani azamankhwala)

Makina ogulitsa I: ACH Njira MMA Mtengo
Pakupanga kwa njira ya ac njira, zida zazikuluzikulu ndi acetone ndi hydrocnic acid imapangidwa ndi acetonic, motero makampani nthawi zambiri amagwiritsa ntchito mawonekedwe a zinthu zopangira. Pakati pawo, matani 0,69 a acetone ndi matani 0,32 a Acrylonile ndi 0,35 matethalol amawerengedwa ngati magwiridwe antchito. M'malo okwera mtengo a ac njira, acetone amatenga ndalama zambiri zoyambirira kwambiri, kutsatiridwa ndi hydrocnic acid zopangidwa ndi acrylonitrile, ndi maakaunti a methanol a kokang'ono kwambiri.

Malinga ndi mayeso ophatikizira a acetone, methal ndi acrylonile m'zaka zitatu zapitazi, zimapezeka kuti kulumikizana kwa a AC Itha kuwoneka kuti pali kusiyana pakati pa izi ndi gawo lomwe lingakhale mu MMA, komwe gawo lalikulu la Mmasalika pamtengo, pomwe kusintha kwamitengo kwa methanol kukukhudzanso acetone.

Komabe, gawo la mtengo wa methanol limangokhala pafupifupi 7%, ndipo gawo la mtengo wa acetone ili pafupifupi 26%. Pakuphunzira unyolo wamtundu wa MMA, ndikofunikira kuti muwone zosintha za acetone.

Ponseponse, mtengo wamtengo wa a A A A A AF makamaka amachokera ku kusintha kwa mtengo wa acetone ndi methanol, omwe acetone ali ndi vuto lalikulu pamtengo wa MMA.

Makampani opanga II: C4 Njira MMA TOX TEME

Pamitengo yamtengo wapatali ya njira ya C4, zopangira zake ndi isobutlene ndi methanlene, womwe mwa Indinol ndi chinthu chapamwamba ndichinthu choyera, chomwe chimachokera ku MTBA yopumira. Ndipo Methanol ndichinthu cha methanol, chomwe chimachokera ku malasha.

Malinga ndi kuchuluka kwa C4 MMA, mtengo wosinthika wa isosutene unit ndi 0.82 ndi methanol ndi 0,35. Ndi kupita patsogolo kwa aliyense muukadaulo wopangidwa, kugwiritsa ntchito mankhwalawo kwafupika ku 0,8 m'mafashoni, omwe achepetsa mtengo wa C4 MMA mpaka pamlingo wina. Enawo ndi mtengo wokhazikika, monga madzi, magetsi ndi mtengo wamagetsi, ndalama zachuma, ndalama zamankhwala ndi zina.

Mmenemo, gawo la imobutne wapamwamba kwambiri mu mtengo wa MMA pafupifupi 58%, ndipo gawo la methanol pamtengo wa MMA pafupifupi 6%. Itha kuwoneka kuti isoosutene ndiye mtengo waukulu kwambiri ku C4 MMA, komwe kusinthika kwamitengo kwa Issutene kumakhudza kwambiri mtengo wa C4 MMA.

Njira yofunika kuyimitsa chiyero chachikulu ichorotene imayambiranso kusinthika kwa mitengo ya MTBE, yomwe imadya 1.57 Intaneti yoposa 80% ya mtengo wa chiyero chachikulu. Mtengo wa MTBE umachokera ku Methanol ndi pre-ether c4, komwe kupangidwa kwa ST-Ether C4 kumalumikizidwa ndi chakudya cha mtengo.

Kuphatikiza apo, ziyenera kudziwidwa kuti kuyera kwakukulu kwa TErt-butanol kuchepa thupi, ndipo mabizinesi ena adzagwiritsa ntchito TAR-butanol monga maziko a maonda a MMA, ndi unit. Malinga ndi kuwerengera kwa Terrt-butanol 6200 Yuan / Ton, Ton-atter-butanol maakaunti pafupifupi 70% ya MMA mtengo, womwe ndi wokulirapo kuposa Isolitene.

Mwanjira ina, ngati mgwirizano wa TErt-butanol umagwiritsidwa ntchito, kusinthasintha kwa mtengo wamtengo wa C4 Njira ya Mma, The Rustight ndi wamkulu kuposa wa Isolitene.

Kuyambiranso, mu C4 MMA, kuwongolera kulemera kwa phindu pamtengo kuti ukhale wotsika: Tert-stanol, Irosutene, Methanol, mafuta.

Makampani Anching III: Ethylene Carbonulation MMA Mtengo

Palibe vuto lopanga mafakitale la MMA ndi Ethylene Carbonulation ku China, motero zovuta za kusinthasintha sizingaganizidwe ndi kupanga kwa mafakitale. Komabe, malinga ndi kumwa kwa ethylene ku Ethylene Carbonulation, Ethylene ndiye mtengo waukulu womwe umatulutsa mtengo wa MMA Mwalawu, womwe ndi wopitilira 85%.

 
Makampani opanga IV: PMMA TRAT

PMMA, monga chowonjezera chachikulu cha MMA, maakaunti oposa 70% ya kumwa pachaka kwa MMA.

Malinga ndi mawonekedwe amtundu wa PMMA, momwe amagwirizira kumwa mankhwala a mma ndi 0,93, mmaaan ndi PMMA / TOAN, yomwe imakhala yochulukirapo.

Mwanjira ina, kusinthasintha kwamtengo kwa MMA kumathandizira kwambiri pakusintha kwa PMMA, komwe kumathandizira mwamphamvu. Malinga ndi kuphatikiza kwa mitengo pakati pa awiriwa m'zaka zitatu zapitazi, kulumikizana pakati pa awiriwo ndi kopitilira 82%, komwe kumakhala kokongoletsedwa kwamphamvu. Chifukwa chake, kusinthasintha kwamtengo kwa MMA kumapangitsa kusintha kwamitengo kwa pmma mbali yomweyo ndi kuthekera kwakukulu.
