乙烯基乙炔

结果表明，Pd－Pb／Al2O3催化剂在一定工艺条件下可以将碳四馏份中的乙基乙炔和乙烯基乙炔分别除至1.0×10－5以下，并且保证丁二烯损失小于3%。

It is found that with certain reaction conditions Pd Pb / Al 2O 3 is an effective catalyst . After hydrogenation both ethylacetylene and vinylacetylene contents are reduced to below 1 0 × 10 - 5 , and 1,3 butadiene loss does not exceed 3 %
