摘要: 研究了固体磷酸催化剂的活性与其自由磷酸聚合态及磷酸硅晶型的关系,指出高活性磷酸催化剂应具备的条件,即自由磷酸中应为正磷酸和焦磷酸的混合物,结合态磷应具有"C"晶型。

关键词: 固体磷酸催化剂, 齐聚, 酸催化

Abstract: The relationship between the catalytic activity of mixed butenes oligomerization over solid phosphoric catalysts and polycondensate of phosphoric acid,the crystalline forms of silicium phosphate in the catalyst have been studied.It was suggested that high activity component of solid phosphoric acid catalyst should be a mixture of pyro and ortho-phosphoric acid and crystalline"C"form of silicium phosphate.

Key words: Solid phosphoric acid catalysts, Oligomerization, Acid catalysis
