Antoy paraan na acetylene parad pangiparaan na maleic anhydride manlapud 1,4-butanediol?

Acetylene method parad 1,4-Butanediol panagparaan na maleic anhydride.

Unona, say acetylene et onreak ed formaldehyde diad kiwawala na Cu-Bi catalyst ed 98kPa tan 80-95°C pian makapawala na 1,4-butynediol. Insan, say 1,4-butynediol et na-hydrogenate ed 1,4-butenediol diad silong na catalysis na skeletal nickel ed 1.372-2.06MPa tan 50-60°C. Kayari to, say kaaruman ya catalytic hydrogenation (13.7-20.6MPa, 120-140°C) et ginawa ya walay Ni-Cu-Mn/Al2O3 pian naporma so 1,4-butanediol. Kayari na pangekal ed saray metal ya ion panamegley na ion exchange resin, say puron 1,4-butanediol et naala panamegley na distillation tan purification.

Akin et pilien so Maleic Anhydride? Saya so manunan sengegan na sankatageyan ya unsaturated polyester resins, tan saya so mangilukas na nanduruman kemikal ed leksab (BDO, THF, tan arum nira). Man-mensahe kayo natan pian nanengneng yo ray solusyon ed MA parad negosyo yo!
