乙炔乙酸化反应中Zn基催化剂的研究进展

Research Progress of Zn Catalysts in Acetylene Acetoxylation

醋酸乙烯是一种重要的有机化工原料,主要采用电石乙炔法生产,反应原料采用的是醋酸和乙炔。目前工业上使用醋酸锌/活性炭催化剂,存在转化率低、易积碳、活性组分易流失等问题。通过调研国内外乙炔乙酸化Zn基催化剂的发展现状,结合我国的基本国情和绿色化学的理念,对乙炔乙酸化反应中Zn基催化剂的发展进行展望。

Vinyl acetate is an important organic chemical raw material,mainly produced using calcium carbide acetylene,and the reaction raw materials are acetic acid and acetylene.At present,zinc acetate/activated carbon catalysts used in industry have some problems,such as low conversion rate,easy carbon accumulation and loss of active components.By investigating the current development status of Zn catalysts in acetylene acetoxylation at home and abroad,combining with the basic national conditions and the concept of green chemistry,the development of Zn catalysts in acetylene acetoxylation reaction was prospected.
