carbonylation

1.The sythesis of Monuron herbicide by oxidative-reductive carbonylation of dimethyamine and p-ClC6H4NO2 using selenium as catalyst and organic base as cocatalyst was studied.

研究了以硒为催化剂,有机胺为助催化剂,对氯硝基苯和甲胺为反,经高选择性氧化还原羰基化一步合成灭草隆除草剂。

2.he catalysis principle of carbonylation ofacetylene to acrylhte, butyl propionate andbutene diacidic ester is reviewed.The reactionkinetics and mechanism are discussed too.

述了乙炔羰化反合成丙烯、丙和顺、反丁烯的催化作用原理，并对反动力学和机理进行了讨论。

3.two tech-nologies,hydroearbylation to produce ethylbenzene and carbonylation to propionic aldehyde and pro-pionic acid, are emphatically evaluated.

结果表明，烃化制乙苯经济性能较差，但技术、市场占优，建议优先考虑；
