Molecular Formula | C50H82O17 |
Physical and Chemical Properties | Chemical quality This product is a light yellow or orange-yellow oily liquid. After cooling, it is in a semi-flow state. It is easily soluble in water and various organic solvents, does not electrolyze in water, and is stable in acid-lye. It is easy to crack in contact with oxidant at high temperature and has good emulsifying performance. |
Use | Purposes of this product and milk 500, 700 mixed into emulsifier, can greatly reduce the amount of milk, reduce the cost of pesticides. |
put 1 mol phenol into the reaction kettle, heat and melt, and then cool to 50 ℃ without sulfuric acid as catalyst. Then raise the temperature to 120 ℃, add 1.5 mol of styrene dropwise, react at 130~140 ℃ for 1 h after dropwise addition, cool down, drive the feed liquid into the condensation kettle, add 50% sodium hydroxide to adjust the pH value to about 11.0~13.0, dehydrate, replace the air in the kettle with nitrogen after dehydration, drive the air clean, and start to pass ethylene oxide. Heat preservation 130~150 ℃, pressure 0.2~0.3MPa. Pass to about 17 mol and continue the reaction for half an hour. The feed liquid is pumped into the neutralization kettle and neutralized with acetic acid to a pH value of 5.0~7.0. The finished product is filled with cooling and discharging materials.
