摘要： PURPOSE: To obtain an aqueous suspension containing an organic peroxide, useful as a polymerization initiator of polystyrene, etc., and transport able with a pump without causing clogging, by using tribasic calcium phosphate as an active component.
CONSTITUTION: An aqueous suspension containing an organic peroxide is prepared by compounding tribasic calcium phosphate. The liquid can be prepared e.g. by adding a necessary amount of tribasic calcium phosphate to a definite amount of water, dispersing under stirring, optionally adding and dispersing a dispersion stabilizing assistant in the dispersion, adding a required amount of powder (benzoyl peroxide) moistened with water, and stirring the mixture. Even if a partial phase-separation takes place in the above suspension, the suspension can be homogenized easily by the light shaking or stirring, to enable the approach to the practical adoption of the automatic charging system with a pump. In the conventional process, the charge of the peroxide has to be carried out through a manhole and accordingly the operation of a polymerization plant in closed system has been impossible. The present process clears the way for the operation of the plant in closed system.

摘要翻译：目的：通过使用磷酸三钙作为活性成分，得到含有有机过氧化物的水性悬浮液，其可用作聚苯乙烯等的聚合引发剂，并可通过泵输送而不引起堵塞。构成：含有有机过氧化物的含水悬浮液通过配合磷酸三钙制备。液体可以例如制备。通过向一定量的水中加入必要量的磷酸三钙，在搅拌下分散，任选地在分散体中加入和分散分散体稳定助剂，加入所需量的用水润湿的粉末（过氧化苯甲酰），并搅拌混合物。即使在上述悬浮液中发生部分相分离，也可以通过轻摇或搅拌容易地使悬浮液均质化，从而能够实现采用泵的自动计费系统。在常规方法中，过氧化物的电荷必须通过人孔进行，因此聚合装置在封闭系统中的操作是不可能的。本程序清除了封闭系统中工厂运行的方式。
