YieldReaction ConditionsOperation in experiment
68% With piperdinium acetate; at 120℃; for 20h; With stirring, 2L four-necked flask of a rectification column, n-<strong>[14447-15-5]propyl cyanoacetate</strong> was added 254g (2.0mol), the catalyst2-methylpiperazine propionate 0.348g, di-n-propoxy methane 714g (7mol), stir heated and maintained at a reaction temperature of 120 ,20h post-test reactor wherein like cyanide content acetate, n-propyl acetate, n-propyl cyanide original of 0.39% (wt%), vacuum distillationThe reaction of an excess of n-propanol and di-n-propoxy methane feedstock distillation from the reaction system out. Glass flaskP-toluenesulfonic acid was added 25mg, BHT0.483g, the cracking temperature 160-220 / 2mbar distilled off under crude cyanoacrylatePropylene monomer 239.9g. The crude monomer pot temperature 80-95 / 1.5mbar purified by distillation to be finished next cyanoacrylate, n-propyl177.3g, content 98.8%, n-propyl acetate to cyanide total income was 63%, Following the procedure of Example 9 Preparation of n-propyl cyanoacrylate, except that: the catalyst used is acetic 0.002molAcid piperidine salt. Ultimately resulting finished cyanoacrylate, n-propyl 190.6g, content 99.2%, n-propyl acetate ester with cyanide yield based68%.
