Ndeipi nzira yeacetylene yekugadzira maleic anhydride kubva ku1,4-butanediol?

Nzira yeAcetylene ye1,4-butanediol kugadzirwa kwe maleic anhydride.

Kutanga, acetylene inopindirana ne formaldehyde kana paine Cu-Bi catalyst pa 98kPa uye 80-95°C kuti igadzire 1,4-butynediol. Zvadaro, 1,4-butynediol inoiswa hydrogen mu 1,4-butenediol pasi pe catalysis ye skeletal nickel pa 1.372-2.06MPa uye 50-60°C. Tevere, imwe catalytic hydrogenation (13.7-20.6MPa, 120-140°C) inoitwa neNi-Cu-Mn/Al₂O₃ kuti igadzire 1,4-butanediol. Mushure mekubvisa ma ions esimbi kuburikidza ne ion exchange resin, 1,4-butanediol yakachena inowanikwa nekudistillation nekucheneswa.

Sei uchifanira kusarudza Maleic Anhydride? Ndiyo musimboti wemaresini epolyester asina kuguta emhando yepamusoro, uye inoburitsa makemikari akasiyana-siyana (BDO, THF, nezvimwewo). Titumirei meseji izvozvi kuti muongorore mhinduro dzeMA dzakagadzirirwa bhizinesi renyu!
