Menene hanyar acetylene don shirya maleic anhydride daga 1,4-butanediol?

Hanyar Acetylene don 1,4- shirye-shiryen butanediol na maleic anhydride.

Da farko, acetylene yana amsawa da formaldehyde a gaban mai kara kuzari na Cu-Bi a 98kPa da 80-95°C don samar da 1,4-butynediol. Sannan, ana haɗa 1,4-butynediol zuwa 1,4-butenediol a ƙarƙashin catalysis na kwarangwal nickel a 1.372-2.06MPa da 50-60°C. Na gaba, ana yin ƙarin catalytic hydrogenation (13.7-20.6MPa, 120-140°C) tare da Ni-Cu-Mn/Al₂O₃ don samar da 1,4-butanediol. Bayan cire ions na ƙarfe ta hanyar musayar ion, ana samun 1,4-butanediol mai tsabta ta hanyar tacewa da tsarkakewa.

Me yasa za ku zaɓi Maleic Anhydride? Ita ce ginshiƙin resin polyester marasa cikawa, kuma tana buɗe nau'ikan sinadarai daban-daban na ƙasa (BDO, THF, da sauransu). Aiko mana da saƙo yanzu don bincika mafita na MA da aka keɓance don kasuwancinku!
