This product is light yellow oily liquid. She has a light milk flavor. Soluble in ethanol, acetone, esters, aromatic hydrocarbons, chloroform, carbon tetrachloride and other organic solvents, slightly soluble in water. The thermal decomposition temperature was 240~280, and the hydrolysis stability was good. With the general organic solvent can be miscible, but insoluble in aliphatic hydrocarbons, refractive index 1. 4745(20 °c), Boiling Point: 194 °c (10 mmHg). Freezing point <- 64 ℃, flash point 225 ℃, thermal decomposition temperature 240~280 ℃, hydrolysis stability is good.
phosphorus oxychloride and sodium metaphosphate were put into the reaction vessel. The air was exhausted by nitrogen flooding, ethylene oxide was introduced under vacuum, and stirred at 45~50 °c for 2~3H. Excess ethylene oxide was distilled off, followed by neutralization to neutral by adding alkali, washing with water, and vacuum dehydration to obtain a finished product.
This product is widely used in chemical fiber fabrics, cellulose acetate as flame retardant, in addition to self-extinguishing, but also can improve water resistance, cold resistance and antistatic. General dosage of 5~10. This product is an excellent flame retardant for synthetic materials, and has a good effect of increasing, widely used in cellulose acetate, Nitro fiber varnish, ethyl cellulose, polyvinyl chloride, polyvinyl acetate, polyurethane, phenolic resin, etc, in addition to the self-extinguishing properties of the products, the physical properties of the products can be improved, and the products are soft, which can also be called petroleum additives and rare element extractants, it is also the main flame retardant material of flame retardant rubber conveyor belt, and the general addition amount is 5% ~ 10%.
