十二烷基三甲基氯化铵1231的作用
在油墨中的作用：为提高油墨中主要组分色料和连结料的功能和改善油墨的其他特性，在油墨生产中需加入助剂。助剂的主要成分为表面活性剂，在油墨中加入具有适宜表面活性、润湿、扩展性能的表面活性剂，十二烷基三甲基氯化铵（活性物含量：50%）或十八烷基三甲基氯化铵（活性物含量：70%）可使油墨具有良好的流变性、流平性、转移性、粘附性及使油墨具有良好的涂膜等。
在金属萃取剂中的作用：由于季铵盐萃取剂如十二烷基三甲基氯化铵带有正电荷，所以对金属阳离子的萃取不取决于PH值，金属的洗脱也不必调整PH值，可直接用这类萃取剂的选择性差；使用季铵盐萃取剂时，必须在酸性或接近中性的溶液中进行萃取。季铵盐萃取剂常用于硫酸镍处理液中分离钻，铜和锌。此外，季铵盐类和胺类萃取剂还可用于从废催化剂中回收贵金属，稀土元素的分离，铌，锑与铬的分离，无机酸的提纯，从氧化钻的过滤液体中除去铁等。黄金萃取可用三辛基甲基氯化铵。
在血样分析中的作用：十二烷基三甲基氯化铵能溶解红细胞，留下白细胞，在自动化血液分析仪中多用作溶血剂。
十二烷基三甲基氯化铵可用作硝基还原重排法制造对胺基苯酚的转移催化剂；还可利用它的乳化性生产建筑防水涂料乳化剂；护发素乳化剂；化妆品乳化剂；阳离子氯丁胶乳的乳化剂；油田钻凿深井时，用作抗高温油包水乳化泥浆的乳化剂等，青霉素发酵工艺过程中的蛋白质凝聚剂；亦可用于生产合成纤维抗静电剂、乳胶工业的防粘剂和隔离剂、工农业用杀菌剂等。

The role of dodecyltrimethylammonium chloride 1231
The role of additives in ink production: In order to enhance the functionality of the main components, colorants and binders, and improve other characteristics of ink, additives need to be added in ink production. The main component of additives is surfactants. Adding surfactants with suitable surface activity, wetting, and expansion properties to ink, such as dodecyltrimethylammonium chloride (active substance content: 50%) or octadecyltrimethylammonium chloride (active substance content: 70%), can give ink good rheological, leveling, transferability, adhesion, and make the ink have good coating properties.
Function in metal extractants: Due to the positive charge of quaternary ammonium salt extractants such as dodecyltrimethylammonium chloride, the extraction of metal cations does not depend on the pH value, and the elution of metals does not require adjusting the pH value. This type of extractant has poor selectivity when used directly; When using quaternary ammonium salt extractants, extraction must be carried out in acidic or near neutral solutions. Quaternary ammonium salt extractants are commonly used to separate drill, copper, and zinc in nickel sulfate treatment solutions. In addition, quaternary ammonium salts and amine extractants can also be used for the recovery of precious metals from waste catalysts, separation of rare earth elements, separation of niobium, antimony and chromium, purification of inorganic acids, and removal of iron from filtered liquids of oxidized diamonds. Gold extraction can be carried out using trioctylmethylammonium chloride.
Role in blood sample analysis: Dodecyltrimethylammonium chloride can dissolve red blood cells, leaving white blood cells behind. It is often used as a hemolytic agent in automated blood analyzers.
Dodecyltrimethylammonium chloride can be used as a transfer catalyst for the production of p-aminophenol through nitro reduction rearrangement method; It can also be used to produce building waterproof coating emulsifiers through its emulsifying properties; Hair conditioner emulsifier; Cosmetic emulsifiers; Emulsifiers for cationic chloroprene latex; When drilling deep wells in oil fields, it is used as an emulsifier for high-temperature oil in water emulsified mud, and as a protein coagulant in the penicillin fermentation process; It can also be used in the production of anti-static agents for synthetic fibers, anti adhesive and isolation agents for latex industry, and fungicides for industry and agriculture.
Technical indicators of dodecyltrimethylammonium chloride:
Appearance: White or light yellow paste like substance
Active substance content: 50 ± 2.0%
Free amine content: ≤ 2.0%
PH value (10% aqueous solution) 6.0-8.0
Packaging and storage: net content of 50 kilograms per plastic drum. It should be sealed and stored indoors. During transportation and storage, it should be handled with care, anti-collision, and antifreeze to prevent damage and leakage.
