In the meanwhile, the effects of varied acids for protecting third carbonyl group were investigated. Through the trial and error, the mixture of anhydrous alcohol/ petroleum benzine is the good solvent of target molecule recrystal.

, and the pyrolytic products of WPS were benzene, methyl benzene, styrene and ethyl benzene which were identified by GC. Methylbenzene was used as the internal stand.

通过气相色谱分析可知，裂解产物为苯、甲苯、苯乙烯和乙苯。

Conclusion: The property of resin is good when the brine's concentration is30%, the degree of crosslinking is14%, methyl benzene as diluent is0.1.

结论：盐溶液浓度约为30%，交联刺14%，致孔剂甲苯为单体的0.1倍时，所得树脂性能良好。

The depressant was produced by using acrylic alkyl ester and vinyl acetate as raw materials, methyl benzene as solvents, azobisisobutyronitrile as initiator by constant temperature polymerization.

AV柴油降凝剂，是以丙烯酸酯、醋酸乙烯酯为原料，以甲苯为溶剂，以偶氮二异丁腈为引发剂，恒温聚合制得。

The decomposition reaction was carried out using methyl benzene as solvent with reaction time of 1 h.
