Introduction | Diphenyl isooctyl phosphate (C20H27O4P) is a colorless and transparent oily liquid, mainly used as a flame retardant plasticizer, almost compatible with major industrial use All resins and rubbers are compatible, and have better compatibility with polyvinyl chloride, low volatility, good plug resistance and weather resistance. They are used in conjunction with phthalate plasticizers, it can improve the toughness and weather resistance of the product, and can improve the tensile strength when used in polyvinyl chloride film. |
preparation | 76.5g(0.5mol) of phosphorus oxychloride (first, phosphorus oxychloride is put into a preheater for preheating, the preheating temperature is 50-60 ℃, 0.75g (1% of phosphorus oxychloride weight) and 94g(1mol) of phenol are added at the same time of preheating, and the reaction tower temperature is 118-120 ℃, the vacuum degree is 70 ~ 75KPa. After the material is reacted in the reaction tower for 30 minutes, it is input into the decompression reactor, reaching 120 ℃ at the top of the tower, 150 ℃ at the bottom of the tower, and the vacuum degree is 30KPa. The monophenylphosphoyl chloride intermediate and some phosphorus oxychloride are recycled and reused. The remaining intermediate diphenylphosphoyl chloride 183g(1mol) and isooctanol 195(1.5mol) in the decompression reactor are pumped into the reaction tower for reaction, the temperature of the reaction tower is 68~70 ℃, the vacuum degree is 70 ~ 75KPa, and the reaction time is 30 minutes to obtain crude diphenyl isooctyl phosphate. The obtained crude diphenyl isooctyl phosphate is washed with 3% sodium hydroxide solution in the reaction kettle, washed and layered with water, distilled to 100 ℃ under reduced pressure, and the vacuum degree is 70 ~ 75KPa to obtain the finished diphenyl isooctyl phosphate with a yield of 90%. |
use | this product is a flame retardant plasticizer, which is compatible with almost all resins and rubbers used in major industries and has better compatibility with polyvinyl chloride. Low volatility, good plug resistance and weather resistance. When used in conjunction with phthalate plasticizers, it can improve the toughness and weather resistance of the product. When used in PVC film, it can improve tensile strength and improve Wear resistance and humidity resistance. It can also be used as a flame retardant plasticizer for synthetic rubber. Phosphate plasticizers, including this product, are characterized by flame retardancy and strong antibacterial properties. The largest yield of tricresyl phosphate (TCP), toluene phosphate (CDP) and triphenyl phosphate. The toxicity of phosphate esters is generally strong. This product is the only phosphate ester allowed to be used in food packaging materials. used as additive flame retardant and flame retardant plasticizer, suitable for synthetic resin and synthetic rubber can improve weather resistance, abrasion resistance, moisture resistance and toughness. Store in a cool, ventilated warehouse. |
Production method | It is obtained by reacting 2-ethylhexanol with phosphorus oxychloride and then esterifying with sodium phenol. Kg/ton phenol 736 phosphorus oxychloride 5002-ethylhexanol (≥ 97%)425 |
