didodecyl dimethyl-γ-diquaternium salt

molecular structural formula:
Another names：
Double alkyl-γ- diquaternium salt
Feature:
Include both performance of double alkyl single quaternary ammonium salts and monoalkyl bisquaternary ammonium salt, with strong adsorption, hydrophobic, soft, anti-static, anti-corrosion, and also have the ability as germicidal lamp.
Purpose:
1. Used as emulsifier, softening agent, adsorbent, fungicides, antistatic agents. use for ore flotation, bitumen emulsion, fabric soft, metal corrosion, plastics processing, sterilization and algae killing .
2 Be used for oil field injection water to sterilize. In oilfield re-injection of sewage, there are a large number of microorganisms, such as:sulfate-reducing bacteria (SRB), iron bacteria, saprophytic bacteria. In the process of their growth, metabolism, and reproduction, these microorganisms can cause severe corrosion of drilling and production equipment, water injection pipeline and other metal materials, they also clog pipes, and damage to the oil reservoir, which cause the reduction of water injection rate, oil production and gasoline quality. At the same time, these troubles have made the crude oil processing more difficult. All of these result a great economic losses. Currently the main method to control the reinjection sewage bacteria is still adding fungicides. However, there are only several fungicides in common use, such as chlorine dioxide, aldehydes, and quaternary ammonium salt. These fungicides more or less have some defects, such as: large dosage, high toxicity, and heavily polluted. Although the bactericidal effect of the quaternary ammonium salt is good, long-run use will make the SRB produce drug resistance, which resulting in the increase of dosage and processing costs. Thus, the development of new effective fungicides is very necessary.
