Physical and Chemical Properties | Chemical quality This product is a yellow-brown paste, which is soluble in water of various hardness. Its solubility in cold water is higher than that in hot water. It is acid and alkali resistant, and has levelling, emulsification and wetting, and diffusion properties. |
Use | OP-4 and OP-7 are used as leveling agents and emulsifiers in the textile industry. OP-9 and OP-10 are easily soluble in water and resistant to acid, alkali, salt, and hard water. They have good emulsification, leveling, wetting, diffusion, and cleaning properties, and can be mixed with various surfactants and dye precursors; Used as a leveling agent and dispersant for printing and dyeing processing, a degreasing agent for leather and wool, a lubricant for fiberglass textiles, and an emulsifier. |
Non hazardous materials. Store in a dry and ventilated warehouse, away from ignition sources. Protect from sunlight and rain during transportation.
Add octylphenol to the reactor, add KOH of catalyst amount, heat and stir to dissolve. After replacing the air in the kettle with nitrogen, epoxy ethane is introduced at around 100 ℃, and the reaction is carried out at 120-130 ℃ and 0.2MPa. After the introduction, stirring continues until the pressure does not decrease and the reaction ends. Cool and neutralize with ammonia to obtain the product.
1 mol of dodecyl phenol is added into the reaction kettle, KOH in the amount of catalyst is added, and dissolved by heating, stirring and stirring. After replacing the air in the kettle with nitrogen, 10 mol of ethylene oxide is introduced at about 100 ℃, and the reaction is carried out at 0.2 MPa at 120~130 ℃. After the introduction, the stirring is continued until the pressure does not drop. Cool, neutralize with ammonia to get the product.
