Quaternary Ammonium Compounds
FACT SHEET: Quaternary Ammonium Compounds Quaternary ammonium compounds, also known as “quats” or “QACs,” include a number of chemicals used as sanitizers and disinfectants, including benzalkonium chloride, benzethonium chloride, cetalkonium chloride, cetrimide, cetrimonium bromide, cetylpyridinium chloride, glycidyl trimethyl, ammonium chloride, and stearalkonium chloride.[i] In general, quats cause toxic effects through all Mutagenicity routes of exposure including inhalation, Some quats have shown to be mutagenic and to ingestion, dermal application, and irrigation of damage animal DNA and DNA in human body cavities. Exposure to diluted solutions may lymphocytes at much lower levels than are result in mild irritation, while concentrated present in cleaning chemicals.[6] solutions are corrosive, causing burns to the skin and mucous Membranes.

Abstract. The polyethylene glycol allyl glycidyl ether (PGAGE) is an important intermediate for preparing silicone softener that can be synthesized from allyl alcohol polyoxyethylene ether and epichlorohydrin (ECH). The performance parameters including the concentration of ECH, initial boron trifluoride diethyl etherate (BFEE) as well as CaCl2 quality were investigated respectively. The optimum process parameters which can get high capping and low by-product rate are as follows: the ECH concentration is 2.0 M, the initial BFEE concentration is 1.65mM, and the CaCl2 dosage is 1.65g/L. Under these conditions, the maximal yield can be improved to 91.36%, the percent of capping rate is higher than 98.16%, the residual concentration of F- is only 0.63 mg/L. concentrated basic solution, in which the total yield was between 90%~91% by Matsuoka et al.

Corrosive Avoid shock and frictions S26-45-60-61 Storage: Room temperature (Z) Technical and Scientific Information General description and applications Quaternary ammonium compounds are any of a group of ammonium salts in which organic radicals have been substituted for all four hydrogens of the original ammonium cation. They has a central nitrogen atom which is joined to four organic radicals and one acid radical. The organic radicals may be alkyl, aryl, or aralkyl, and the nitrogen can be part of a ring system. They are prepared by treatment of an amine with an alkylating agent. They show a variety of physical, chemical, and biological properties and most compounds are soluble in water and strong electrolytes. Such compounds include: Benzalkonium Chloride ( CAS RN: 8001-54-5) Benzethonium Chloride CAS 121-54-0 Cetalkonium Chloride( CAS 122-18-9) Cetrimide ( CAS 8044-71-1) Cetrimonium Bromide ( CAS 57-09-0) Cetylpyridinium -
