    Hi yihi ndlela ya acetylene yo lulamisa maleic anhydride kusuka eka 1,4-butanediol?

    2. 2.025-12-08

    Ndlela ya acetylene ya 1, .4-Butanediol ya xitsongwatsongwana ku lulamisiwa ka maleic anhydride.

    Xosungula, acetylene yi endla reaction na formaldehyde eka vukona bya Cu-Bi catalyst eka 98kPa na 80-95°C kuva yi humesa 1,4-butynediol. Kutani, 1,4-butynediol yi hydrogenated kuva 1,4-butenediol ehansi ka catalysis ya skeletal nickel eka 1.372-2.06MPa na 50-60°C. Endzhaku ka sweswo, catalytic hydrogenation yin’wana (13.7-20.6MPa, 120-140°C) yi endliwa hi Ni-Cu-Mn/Al2O3 ku endla 1,4-butanediol. Endzhaku ko susa ti ions ta nsimbi hiku tirhisa ion exchange resin, pure 1,4-butanediol yikumeka hiku distillation naku basisiwa.

    Ha yini u hlawula Maleic Anhydride? I nkolo wa top-tier unsaturated polyester resins, xikan’we naku pfula ti khemikhali to hambana hambana tale hansi (BDO, THF, na swin’wana). Hi rhumele rungula sweswi ku lavisisa swintshuxo swa MA leswi lulamisiweke eka bindzu ra wena!
