TL;DR: In this paper, a preparation method of triphenyl phosphate is described, which consists of adding a catalyst into molten phenol, putting a mixture into a reaction kettle, stirring the mixture until the temperature is reduced to below 50 DEG C, stopping stirring and mixing phosphorus oxychloride, performing constant pressure acid drainage and negative pressure acid draining under a stirring condition to ensure that an acid value is less than or equal to 6mg KOH/g, and neutralizing and exhausting to obtain qualified coarse ester; and raising the temperature of the qualified coarse enters to perform

TL;DR: In this paper, a preparation method of 1-chloro-2-propyl esters is presented, which comprises the following steps of preparing ingredients; synthesizing: stirring and slowly dropping the epoxy propane at the temperature of 57 to 62 DEG C for 20+2 hours, pouring the cold water to the reaction tank jacket, controlling internal liquid temperature at 60+3 DEGC, completing the addition of epoxypropane, end-point controlling the PH value at 5.5-6; rinsing the resultant product; dehydrating; analyzing

TL;DR: In this article, a high pressure anti-combustible oil with base oil of tricresyl phosphate and production method thereof, which includes the following components: tricreyl phosphate, di-(tert-butyl phenyl) phenyl phosphate at weight ratio of (1.5-2.0), 1wt-1.

TL;DR: In this paper, a method for producing halogen-containing phosphate by a phosphorus oxychloride excess method is described, which comprises the following steps: (1) ingredient preparation; (2) synthesis: starting stirring, slowly and dropwise adding epoxy compounds at a temperature of 57-62 DEG C for 20+/-2 hours, supplying cold water to a reaction tank jacket to control the temperature of liquid in the tank to be 60+/-3 DEGC, after the addition of the epoxy compound is finished, controlling the end point to be at a

TL;DR: In this paper, a method for the production of a phosphate flame retardant by excess phosphorus oxychloride is described, which includes the steps of: (1) esterification: putting a reaction raw material into a reaction kettle, adding a catalyst, and under a specified temperature, pumping excess phosphorus oxidechloride into the kettle, conducting stirring and heating, controlling different production conditions according to different pyro flame retardants, then discharging the excess oxygen phosphorus through pressure reduced acid discharge, measuring the acid value to see whether it met the standard, and if it meets the standard
