Heteropoly acid, especially phosphorus tungsten acid ( HPW), as a kind of catalyst, with no pollution, multifunction and high activity, has gradually shown a good prospect in organic synthesis and other fields.

When the HPW loading was over 40%, HPW crystal was formed on the surface of unsaturated phosphotungstate and covered some of the acid sites.

负载量大于40%时，在不饱和磷钨酸盐表面形成磷钨酸晶体。

When the HPW loading was in the range of 20%-40%, acidic unsaturated phosphotungstate was formed;

中等负载量（20%～40%）时形成酸性较强的不饱和磷钨酸盐；

Fusel oil and acetic acid were used as raw materials in this experiment with heteropoly acid HPW/ MxOy as catalyzer.

本实验以杂醇油和乙酸为原料，杂多酸HPW/MxOy为催化剂。
