Kodi njira ya acetylene yokonzekera maleic anhydride kuchokera ku 1,4-butanediol ndi iti?

Njira ya acetylene ya 1,4-butanediol yokonzekera maleic anhydride.

Choyamba, acetylene imakumana ndi formaldehyde pamaso pa Cu-Bi catalyst pa 98kPa ndi 80-95°C kuti ipange 1,4-butynediol. Kenako, 1,4-butynediol imasinthidwa kukhala 1,4-butenediol pansi pa catalysis ya skeletal nickel pa 1.372-2.06MPa ndi 50-60°C. Kenako, catalytic hydrogenation ina (13.7-20.6MPa, 120-140°C) imachitika ndi Ni-Cu-Mn/Al₂O₃ kuti ipange 1,4-butanediol. Pambuyo pochotsa ma ayoni achitsulo kudzera mu ion exchange resin, 1,4-butanediol yoyera imapezeka mwa kusungunuka ndi kuyeretsa.

Bwanji kusankha Maleic Anhydride? Ndi maziko a unsaturated polyester resins yapamwamba kwambiri, komanso imatsegula mankhwala osiyanasiyana (BDO, THF, ndi zina zotero). Titumizireni uthenga tsopano kuti mupeze mayankho a MA opangidwira bizinesi yanu!
