Physical and Chemical Properties | Chemical properties The appearance is beige thick liquid or paste. Can dissolve in water. Can be shared with various surfactants. It is a non-ionic active agent. It has good flexibility and lubricity. The storage period is half a year. |
Use | This product is used as a soft treatment agent for synthetic fibers and viscose fabrics. It is also an important component of synthetic fiber oil, such as cyanamide and polyester. It is mainly used as a softener and lubricant additive in the spinning process of synthetic fibers. |
When using, gloves and protective glasses should be worn to avoid direct contact with the skin and eyes. If it gets on the skin, rinse with water and soap. Place in a cool and dry warehouse to prevent exposure to sunlight and rain.
Put 510 parts of stearic acid into the reaction kettle, heat, melt, stir, and raise the temperature to 100 ℃. Add 10 parts of potassium hydroxide solution (50% KOH) and continue to heat up and dehydrate under vacuum. When there are no water droplets or mist on the inner surface of the mirror, nitrogen is used to drive the air clean. Stop vacuuming. Slowly add 510 parts of ethylene oxide, keep it at 180~200 ℃, and pressure ≤ 0.3MPa. After adding, naturally reduce the pressure. Cool it to 80 ℃ and take a sample to measure the saponification value. If the saponification value reaches 90~105, it is the endpoint. Neutralize with 5 parts of glacial acetic acid. Add 100 parts of OP emulsifier and stir at 80 ℃ for 0.5h. Cooling, discharging and packaging to obtain the finished product.

Slowly add 510 parts of ethylene oxide, keep the temperature at 180~200 ℃, pressure ≤ 0.3 MPa, naturally depressurize after addition, take samples to 80 ℃ to measure saponification value, and the saponification value reaches 90~105 as the end point. Neutralize with 5 parts glacial acetic acid. Add 100 parts of OP emulsifier and stir at 80 ℃ for 0.5 h. The finished product is obtained by cooling the discharge package.
