摘要
研究了取代乙酸配体作为Ｎｉｃｕｌａｎｄ催化剂对乙炔二聚反应性能的影响．结果表明，不同功能结构数目的氨羧配体均使催化剂的选择性提高，乙炔转化率略有下降，巯基乙酸配体的加入，则改变了乙炔二聚反应的机理，得到以乙醛为主的产物．
The effect of a series of substituted acetic acid ligand such as acetic acid (HAc),glycinc(GL), nitrilotriacctic acid(NTA), cthylenediamine tetra acetic acid (EDTA),diethylenetriaminepenta acetic acid (DTPA), triethyleneteroaminchexa acetic acid, chloroacetic acid or thioglycollic acid (TGA) as a catalyst promotor of the acctylenc dimerization reaction in Niculand catalyst has been studied systematically. The experimental results showed that the influence of the amino-carboxylic ligand with different number of functional groups was about the same on the Niculand catalyst, its catalytic activity was all negative. However, the reaction mechanism of acctylene dimerization changed entirely as a result of the addition of ligand TGA to the catalytic system with acctaldehyde as the sole product.
