The application discloses a preparation method of tert-butylated triphenyl phosphate, which comprises the following steps: using tert-butyl phenol, phenol and phosphorus oxychloride as raw materials, using a Lewis acid as a catalyst, putting the raw materials and the catalyst into a reactor at one time or in sections, and obtaining a crude tert-butylated triphenyl phosphate after reaction; performing vacuum distillation on the crude tert-butylated triphenyl phosphate, stopping the vacuum distillation when the acid value of the crude tert-butylated triphenyl phosphate is less than or equal to 3 mgKOH / g, and performing molecular distillation treatment on the crude tert-butylated triphenyl phosphate with the acid value less than or equal to 3 mgKOH / g. The tert-butylated triphenyl phosphate prepared by the method has low triphenyl phosphate content, high effective component content, simple preparation method, low production cost and is suitable for industrialized production. The tert-butylated triphenyl phosphate prepared by the method is suitable for the fields of aviation oil and hydraulic oil base oil, plasticizer, flame retardant, lubricating oil extreme pressure anti-wear agent and the like.

This invention relates to a lithium battery immersion cooling medium composition, its preparation method, and its application. The lithium battery immersion cooling medium composition comprises a base oil, a flame retardant, an antioxidant, and pentaerythritol ester; the base oil is a polyalphaolefin, and the flame retardant comprises 3.1-4.2 parts by weight of triisopropylphenyl phosphate, 1.7-3.9 parts by weight of trixylenol phosphate, 2.5-7.8 parts by weight of tert-butylphenyltriphenyl phosphate, 1.6-5.5 parts by weight of isodecyl diphenyl phosphate, and 3.2-6.7 parts by weight of triphenyl phosphate. This lithium battery immersion cooling medium composition maintains good flame retardant performance under low viscosity conditions, better meeting the requirements for lithium battery immersion cooling.

The compositions include phosphates, such as alkyl and aryl phosphates, which have very low or no triphenyl phosphate (TPP) content. Methods of synthesizing phosphates are also disclosed, which target a control of TPP to below 0.1%, substantially reducing the potential toxicity of the products including the phosphates.

This invention relates to the field of refrigerants, specifically to a mixed refrigerant and its preparation method. By weight, the refrigerant comprises 85-95 parts of a basic refrigerant, 1-5 parts of a flame retardant, 1-10 parts of a lubricating oil, and 0.1-0.5 parts of a stabilizer. The basic refrigerant is a mixture of R32, R1234ze(E), and R1234yf in a mass ratio of (18-28):(45-60):(15-25). The stabilizer is a mixture of triethyl orthoformate, triphenyl phosphite, and methylbenzotriazole in a mass ratio of (0.1-0.15):(0.1-0.15):(0.15-0.2). This refrigerant has a low GWP, good flame retardant properties, and good stability.
