| didodecyl dimethyl-γ-diquaternium salt |
Alias: dialkyl-γ-bisquaternium; dodecyl dimethylhydroxypropyl-γ-bisquaternium; dodecyl dimethyl hydroxypropyl bis ammonium chloride
English name: didodecyl dimethyl-γ-diquaternium salt
Properties: It has the dual properties of dialkyl monoquaternary ammonium salt and monoalkyl double quaternary ammonium salt surfactant. It has strong adsorption, hydrophobicity, softness, antistatic, anti-corrosion and sterilization properties.
use:
1. Used as emulsifier, softener, adsorbent, bactericide, antistatic agent, suitable for ore flotation, asphalt emulsification, fabric softness, metal anticorrosion, plastic processing, sterilization and algae killing.
2. Injecting water sterilization for oil fields: In the oilfield reinjection wastewater, there are a large number of microorganisms, such as sulfate reducing bacteria (SRB), iron bacteria, saprophytic bacteria and the like. During the process of growth, metabolism and reproduction, these microorganisms can cause serious corrosion of drilling equipment, water injection pipelines and other metal materials, and block the pipeline, damage the oil layer, cause water injection, oil production and oil and gas quality to decline, and also process crude oil. Difficulties have caused great economic losses. Currently, the main way to control the bacteria in reinjected sewage is still to add fungicides.Compared with 1227 (dodecyldimethyl group chlorination), the double season salt has a higher bactericidal effect, and it can be used interchangeably with other chemicals to not only inhibit the resistance of SRB, but also reduce the processing cost. Chuan. At the same time, double season money salt has excellent water solubility, and has good corrosion inhibition effect on carbon steel.
