The present invention provides a quaternary ammonium etidronate compound (QAE) comprising a quaternary ammonium cation and an etidronate anion, having the Formula I.
A method for the preparation of such compounds is described by reacting a quaternary ammonium salt with an etidronic acid or salt thereof. Variable ratios of each reactant may also be used to form different QAE compounds. The quaternary ammonium etidronate compounds is useful in water treatment, cosmetic, hygiene, personal care, paint, coating, wood treatment, agrochemical, antimicrobial, disinfectant, or biocidal compositions; as the compound provides high anti-corrosive and biocidal properties; and low scaling properties. A water treatment composition is also described, having a QAE compound of Formula I and a water treating biocidal agent, useful in cooling towers and other recirculating water, or recreational water system.
本发明提供了一种四季铵伊德罗酸盐化合物(QAE),包括四季铵阳离子和伊德罗酸阴离子,具有化学式I。通过将四季铵盐与伊德罗酸或其盐反应来描述制备这种化合物的方法。也可以使用不同的反应物比例形成不同的QAE化合物。四季铵伊德罗酸盐化合物在水处理、化妆品、卫生、个人护理、涂料、涂层、木材处理、农药、抗菌剂、消毒剂或生物杀灭剂组合物中有用,因为该化合物具有高抗腐蚀和生物杀灭性能以及低结垢性能。还描述了一种水处理组合物,包含化学式I的QAE化合物和水处理生物杀灭剂,适用于冷却塔和其他循环水或娱乐水系统。
