Summary:
the present invention relates to the technical field of preparation process of polyquaternary ammonium salt 10, and discloses a production process of polyquaternary ammonium salt 10, which comprises the following steps: filling equimolar epichlorohydrin and gas-phase trimethylamine into a reaction kettle, the internal temperature of the reaction kettle is kept at 015 ℃, the PH is 89 alkaline environment, and the pressure is 0.1Mpa. The stirring mechanism of the reaction, heat preservation for at least 1.5 hours to prepare cationic etherifying agent ETA for standby. In the production process of the polyquaternary ammonium salt 10, before rake drying, the product is treated with 0.110% aldehyde, which can keep the product in a loose state, and the processed product is further removed by rake drying. The alcohol and water content can reach 1020%, and the product is kept in a loose state, which can increase the amount of solvent 1020% recovery, save production costs, and shorten the product manufacturing cycle, improve the preparation efficiency of the product and the economic benefits of the enterprise.
