A series of quaternary
ammonium salts (QASs) was synthesized using melamine and sodium chloroacetate as raw materials.
Introducing quaternary
ammonium salts onto the chitosan backbone could be one of the best methods to increase antimicrobial activity as well as water solubility and increasing dye affinity of chitosan.
2004, "Ionic Liquids Based upon Metal Halide/Substituted Quaternary
Ammonium Salt Mixtures," Inorg.
This presentation will investigate polysiloxane coatings containing quaternary
ammonium salt (QAS) moieties for potential application as an environmentally-friendly antifouling/fouling-release coating.
The results above give the obvious conclusions that wet adhesion properties improve as the
ammonium salt within the film decompose, and there is no correlation between the amount of
ammonium salt that has decomposed and wet water crinkle resistance.
Glycyrrhizinic acid occurs naturally in the liquorice plant "Glycyrrhiza glabra" while its
ammonium salt is manufactured from aqueous extracts of the liquorice plant.
A typical quaternary
ammonium salt is again specified, but the level is lower, 2-4% on silica.
The new 2,4-D choline is a quaternary
ammonium salt, which is different from 2,4-D amine or ester formulations.
Components:- Active Ingredient Glyphosate N Phosphonomethyl Glycine In The Form Of Its Isopropyl
Ammonium Salt, Cas No:- 1071-83-6-41.
US Patent 8,871,700 B2: Procter & Gamble has patented a liquid cleaning and disinfecting composition that is comprised of C12-14 linear alkyl dimethyl amine oxide; a Zn2+ salt selected from the group consisting of Zn carbonate, Zn sulphate, Zn citrate and mixtures thereof; an anionic surfactant selected from the group consisting of alkyl sulfate, alkyl ethoxy sulfate and mixtures thereof; an organic solvent selected from the group consisting of ethanol, benzyl alcohol, and mixtures thereof; and at least one biocide selected from the group consisting of a halogenated benzyl alcohol derivative, a halogenated hydroxy-diphenylether, a quaternary
ammonium salt, an alkylbenzethonium chloride, a peroxide bleach system, and mixtures thereof.
NR (standard Malaysian type grade SMR 10) was used as base polymer, reinforced with two kinds of clays: The first clay was modified by dimethyl-di(hydrogenated tallow) alkyl
ammonium salt (clay-QUAT) and the second by octadecylamine (clay-PA).
Smectite-based organoclays are modified with a quaternary
ammonium salt which facilitates compatibility with a variety of organic solvent systems.
