| application | NP-10 Chinese name nonylphenol polyoxyethylene ether, colorless and transparent liquid. It has good wetting, emulsification, dispersion and leveling properties. Used as the main raw material of synthetic detergent. It is also used as an industrial additive and is widely used in textile, papermaking, petroleum, metallurgy and other industries. It is prepared by heating catalytic condensation of nonylphenol and 9 moles of ethylene oxide. The existing synthesis method of nonylphenol polyoxyethylene ether is based on nonylphenol and ethylene oxide as raw materials and polymerized under the action of catalyst. |
| synthesis method for preparing | green modified nonylphenol polyoxyethylene ether. the modified nonylphenol polyoxyethylene ether synthesized by this method is not easy to dissolve nonylphenol in natural environment and avoids many problems caused by nonylphenol. The method includes the following steps: ①Put a certain proportion of glucose into the reaction kettle, use an appropriate amount of deionized water to dissolve, and stir to make the reaction system uniform; ②Add an appropriate amount of catalyst, control the appropriate temperature to add nonylphenol dropwise, and keep the reaction temperature after the dropwise addition. Continue to mature for 30 minutes; ③Raise the temperature to 100-120 ℃ for dehydration for 1 hour, control a certain temperature and pressure to continuously introduce ethylene oxide, after the ethylene oxide is passed, the reaction temperature is kept to be cured for 1 hour, and then an appropriate amount of acid is added to adjust the PH of the material and then the material is released. |
| application | biochemical research; Widely used as W/O emulsifier or O/W emulsifier and dispersant, it is the main raw material of synthetic detergent. It can be used as a compound monomer of chemical fiber oil agent, as a diffusion agent and leveling agent for bleaching, refining and dyeing processes in textile printing and dyeing industry, as wetting agent, foaming agent and mud active treatment agent for oil fields. |
