Abstract:

In the presence of catalyst, phosphino polymaleic acid has been synthesized by using initiator in water phase. The relative molecular weight is 852 by using viscometry, its relative density is 1.164 and pH is 2.2, and the phosphor content is 1.092% .The product has both scale inhibition and corrosion inhibition efficiencies. The result indicates that the scale inhibition rate is 98.05% and the corrosion inhibition rate is 54.884%.

Key words: phosphino polymaleic acid, viscometry, scale inhibition, corrosion inhibition

摘要：

在催化剂的存在下, 在水相体系中使用引发剂合成膦基聚马来酸。采用黏度法测定膦基聚马来酸的相对分子质量为852、相对密度为1.164、pH为2.2、含磷质量分数为1.092%。产品兼有阻垢、缓蚀两种功能, 其中阻垢率为98.05%, 缓蚀率为54.884%。
