CAS NO 78-42-2 Tris 2-ethylhexyl Phosphate

production method:
Sodium alcohol method is the reaction of alcohol and alkali metal hydroxide to produce alkali metal alcoholate, and then with phosphorus oxychloride reaction. Decompression method is under reduced pressure conditions, the alcohol and phosphorus oxychloride direct reaction, the pressure generated HCL generated TOP. At present, China’s production process are TOP TOP method using decompression, the process is as follows: The 2-ethyl ethanol was added to the reactor, cooling and cooling to below 10 ℃, slowly adding phosphorus oxychloride, the reaction was stirred, Gradually heated to 60 ° C, the reaction of hydrogen chloride generated by the pump out after the reaction was added 10% sodium carbonate solution and neutralized, and then washed with water at 80 ℃; vacuum distillation using vacuum distillation crude TOP, removal 2-ethyl ethanol. After the separation of trioctyl phosphate and TOP, the finished product was filtered by filtration.
use:
Anthraquinone hydrogen peroxide can be produced instead of hydrogenated terpineol, the product of high concentration, good quality, less consumption for their own flame retardant, plasticizer, extractant. It is a kind of special plasticizer which has both flame retardancy and cold resistance. Its low temperature property is better than oxalate. It has excellent water resistance, low volatility, excellent gel function and good product Mechanical properties, UV stability, anti-aging, resistance and antibacterial effect. Mainly used in military PVC products, adhesives and coatings, synthetic rubber and fiber, but also for hydrogen peroxide (H2
O2) working solvent, lubricant additives, precious metal extractant. This product is PVC excellent cold plasticizer
First, the low temperature performance is better than adipates, and has anti-corrosion and flame retardant, but poor heat resistance. This product plasticizing performance is poor, and tricresyl phosphate (TCP) and can be used to improve. With dioctyl phthalate (DOP) equal amount and can be used to get self-extinguishing products. This product is mainly used for PVC cable materials, coatings and synthetic rubber and cellulose plastics.

Product expansion
1> Cosmetic Raw Materials: Cosmetics is a variety of raw materials through a reasonable deployment of processing from the compound mixture. Cosmetics with a wide range of raw materials, different performance. According to the raw material properties and uses of cosmetics, can be divided into matrix materials and auxiliary raw materials in two categories. The former is a class of cosmetics in the main raw materials, cosmetics in the possession of a large proportion of the cosmetics play a major role in the role of the material. The latter is the formation of cosmetics, stability or to give color, smell and other characteristics of the role of these substances in the cosmetic formula is not used, but it is extremely important. Cosmetics are natural, synthetic or extracted from the role of different substances as raw materials, by heating, mixing and emulsification and other production processes processed from the chemical mixture.
2> Active Pharmaceutical Ingredients(API): API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute.It is one substance or mixture during the medicine making period, it can not be taken directly by patients.
3> Fragrance And Spices: Spice is a substance that can be scented by smelling or scented by taste, and is the raw material for the preparation of the fragrance. Spices are an important part of fine chemicals, it is composed of natural spices, synthetic spices and single fragrance.
4> Organic Raw Material: Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, pesticides, pharmaceuticals, resins, additives, and other intermediates.
5> Chemicals Used In Paints: Paint, the traditional Chinese name is paint. So-called coating is coated on the surface of the object that be protected or be adornment, and with the continuous film coating to form strong adhesion, usually in resin, or oil, or emulsion is given priority to, add or not add pigment, filler, add the corresponding additives, organic solvents or water preparation of viscous liquid.
