Invention Description

The invention mainly involves a method for synthesizing trioctyl phosphate.

In the traditional synthesis of trioctyl phosphate, negative pressure is usually used to remove hydrogen chloride gas, which has low removal efficiency and only about 70% of hydrogen chloride gas is removed. This will cause more hydrogen chloride gas to dissolve in octanol, which will inhibit the main reaction of generating trioctyl phosphate, also known as Tris(2-ethylhexyl) Phosphate, hereinafter referred to as TOP.

The synthesis method invented by the GXXD Chemical Research Team provides a new TOP synthesis reaction method. Ammonia is gradually introduced during the reaction process, and the ammonia introduction rate and reaction rate are strictly matched, so that the hydrogen chloride generated during the reaction is completely reacted by ammonia to generate ammonium chloride. The uniqueness of this method is that the HCl generated in reaction steps one and two can be quickly reacted and removed, thereby reducing the occurrence of side reactions, so as to ensure that step three in the main reaction of generating TOP can proceed smoothly, so that the final TOP has higher purity and higher yield.

The Significance of This Invention

The invention patent "A method for synthesizing trioctyl phosphate" obtained by GXXD Chemical aims to improve the industrial production efficiency of trioctyl phosphate, reduce the occurrence of side reactions, and reduce the content of impurities such as moisture, dioctyl phosphate, and octanol in the final product of trioctyl phosphate. Trioctyl phosphate with higher purity helps GXXD Chemical better serve partner companies that have demand and high requirements for trioctyl phosphate.

The leadership team of Guangxi Xingda Fine Chemicals came up with the idea of optimizing the synthesis method of trioctyl phosphate in the journey of continuous pursuit of excellence. This invention is not only a technological breakthrough, but also a revolutionary improvement in production efficiency and product quality. By gradually introducing ammonia during the reaction process and strictly matching the ammonia introduction rate with the reaction rate, this invention significantly improves production efficiency and ensures that every ton of finished products can meet or even exceed industry standards.

More importantly, market competition in industries related to trioctyl phosphate, such as hydrogen peroxide, is becoming increasingly fierce. Nowadays, customers have increasingly higher quality requirements for trioctyl phosphate. This invention helps our company produce high-purity trioctyl phosphate with stable quality, which coincides with GXXD Chem's mission of "To Boost Leaps In Our Partner Companies’ Productivity".  With our team members' efforts, we are now more and more confident to say that GXXD chem is the preeminent trioctyl phosphate manufacturer!
