N-octadecylalkyl diquaternium salt
Another name：Double-chain quaternary ammonium salt
Nature：Conclude two weng nitrogen atoms, it has stronger bonding capacity
and adsorption capacity of metal, plastic, fabric, miningthe
compound of non-ionic and amphoteric surfactants, its performance
has been further improvedand water-soluble significantly increased,
strengthening of emulsifying power.
1. Quaternary ammonium salt Cationic surfactant emulsifier, can be
used as asphalt emulsifiers, ore flotation agent, fabric and
finishing auxiliaries, metal processing additives.
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 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.
Compared with 1227, biquaternary ammonium salt has a higher
bactericidal effect, and used with other agents, it not only can
inhibit SRB drug resistance, but also reduce the cost of
processing. Meanwhile, the biquaternary ammonium salt has excellent
water solubility, and also has good corrosion inhibition of carbon
