Properties and stability
1. It has excellent stability, surface activity, emulsification, sterilization, disinfection, softness and antistatic properties.
Storage method
1. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. 2. Keep container sealed. They should be stored separately from oxidants and acids, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. 3. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
Synthesis method
1. Pour tertiary amine into the pressure kettle, add an appropriate amount of isopropyl alcohol and no reaction medium, and then add a small amount of sodium hydroxide as a catalyst. Replace the air in the kettle with nitrogen, raise the temperature to 50°C, and introduce 1% (mass) excess of methyl chloride than the theoretical amount. Close the autoclave. React at 0.5 MPa for 4 hours. The reaction is over. After desalination, dilute with water to the required concentration. The finished product is ready for canning.
Purpose
1. Used as antistatic agent for textile fibers, hair conditioner, and emulsifier for asphalt, rubber and silicone oil. And widely used as disinfectant.
2.Generally, those with active substances greater than 3 4% are used as asphalt emulsifiers and soil waterproofing agents. Other products are used as antistatic agents for synthetic fibers, additives for oil paint cosmetics, hair conditioners, disinfectants, fabric fiber softeners, soft detergents, silicone oil emulsifiers, etc.
