Production device and method for epoxy plasticizer

Abstract

The invention discloses a production device and method for an epoxy plasticizer. A grease inlet, a circulation inlet and a grease outlet are formed in an epoxy stirring tank; a heating coil and a cooling coil are arranged in the epoxy stirring tank; an outlet valve is arranged on the grease outlet; an upper inlet, a lower inlet and a discharge port are formed in an epoxy reaction mixer; a hydrogen peroxide pump and a hydrogen peroxide hydrogen peroxide are sequentially connected with the lower inlet of the epoxy reaction mixer; the outlet valve, a circulating pump, a grease flow control valve and the upper inlet are connected sequentially; and the discharge port, a cooler and the circulation inlet are connected sequentially. According to the invention, under the condition that the temperature is controlled at about 60 DEG C, a reaction only requires 6 hours, the speed is increased by at least 50% compared with the conventional method, the epoxy value of a product is increased remarkably and can reach 6.7 to the maximum, the product quality is improved, the reaction time is shortened, the reaction efficiency is increased, and energy consumption is reduced.

Description

technical field [0001] The invention relates to a production process of an epoxy plasticizer, in particular to a production device and method of an epoxy plasticizer. Background technique [0002] Now the traditional production method of epoxy plasticizer is to drop hydrogen peroxide into the epoxy reaction mixer and stir to make hydrogen peroxide and oil react. The contact between hydrogen peroxide and oil is not enough, so the production time is long, resulting in side reactions Many, the epoxy value of the product is not high. For example, taking soybean oil with an iodine value of 130 and an iodine value of 3 after the reaction, the epoxy value of complete epoxidation can reach 8 / 108*100=7.4 in theory, but in fact the highest epoxy value can only reach 6.50 (Using the hydrochloric acid acetone method to detect), indicating that there are many side reactions in this reaction, mainly due to the long reaction time and high temperature. Cause reaction time is long, reactio...

[0002] Now the traditional production method of epoxy plasticizer is to drop hydrogen peroxide into the epoxy reaction mixer and stir to make hydrogen peroxide and oil react. The contact between hydrogen peroxide and oil is not enough, so the production time is long, resulting in side reactions Many, the epoxy value of the product is not high

For example, taking soybean oil with an iodine value of 130 and an iodine value of 3 after the reaction, the epoxy value of complete epoxidation can reach 8 / 108*100=7.4 in theory, but in fact the highest epoxy value can only reach 6.50 (Using the hydrochloric acid acetone method to detect), indicating that there are many side reactions in this reaction, mainly due to the long reaction time and high temperature

The reaction time is long and the reaction temperature is high. The main reason is that peroxyformic acid and oil are not miscible and cannot be fully contacted.
