performance and application
The penetrant JFC is easily soluble in water and has excellent permeability. It does not affect the penetration above the cloud point.
As a penetrant in the textile industry, it can be used in sizing, desizing, scouring, bleaching, carbonization and other processes.
leather industry can be used as penetrant or degreasing agent.
The penetrant JFC has strong hair washing ability, is easy to wash off various oil stains and feels soft.

production method
put 480 parts of C7 ~ C9 fatty alcohol into enamel kettle with stirring, put 4 parts of solid alkali into dissolution tank and then put them into reaction kettle. Stir gradually heat up and dehydrate under vacuum. When the temperature rises to about 120 ℃ and no water droplets can be seen from the surface of the mirror, stop dehydration. Continue to raise the temperature to 150 ℃, vacuum the air in the kettle, and fill nitrogen to remove the air. Then ethylene oxide is added under stirring, the reaction pressure is about 0.2 MPa, the reaction temperature is 160~180 ℃, and the cloud point is measured after a period of reaction. The reaction was terminated after the cloud point was qualified. Cooling the discharge.
