Low Toxicity And Excellent Performance N-octadecylalkyl Diquaternium Salt

Mainly 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 results 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. As a typical representative of the new fungicide family, the biquaternary ammonium salt attracts widespread attention for its low toxicity, excellent performance. Biquaternary ammonium salt, also known as, Esterquat Gemini surfactant.
