| Name | alkyl phenylsufonate |
| Synonyms | alkyl phenylsufonate |
| Molecular Formula | C18～24H30～42O3S |
| Physical and Chemical Properties | The chemical quality product is a light yellow transparent oily liquid with relative density (25 ℃) of 1.03~1.07, viscosity (20 ℃) of 0.1~0.13 Pa s, boiling range of 211~279 ℃(1 333 kPa), refractive index nD301.494 ~ 1.500, and thermal volatilization <0.2% (100 ℃,6 h). The volatility is small, non-toxic, but the compatibility with PVC resin and the cold resistance of the product is poor. |
| Use | This product is used as a plasticizer for PVC and Vinyl Chloride Copolymer, mainly used for PVC film, artificial leather, sole, wire and cable and other products. Because of the deep color is not easy to use in light-colored products, can be used as natural rubber and synthetic plasticizer, improve the low temperature flexibility and resilience of rubber products, also used in synthetic detergent industry. |
the reaction is carried out in 2~5 tandem kettles. kerosene wax (C12 ~ 18) is first added to the first kettle, and then overflowed to the next kettle in turn. sulfur trioxide and chlorine gas are introduced from the distributor at the bottom of each reactor in a certain proportion. The introduction amount is the most in the first kettle and decreases in turn, so that most of the reactions are completed in the first kettle with lower material viscosity. In the first kettle temperature 40 ℃, residence time 15 min, the second kettle temperature 50 ℃, residence time 8 min, the formation of alkyl sulfonyl chloride into the esterification kettle, at 65 ℃ with sodium phenol esterification reaction. After the reaction, wash with water until neutral, evaporate unreacted C12 ~ 18 alkanes, decolorize the high boiling point by sodium hypochlorite, and press filtration to obtain the finished product.
