Didecyl dimethyl ammonium chloride

The crude oil extracted from primary and secondary oil recovery is mostly W/O emulsion, and the stabilizing agents for this type of emulsion are cyclic acids, asphaltene acids, and some oil wet solid particles (such as microcrystalline wax, asphaltene particles, etc.) in the crude oil. The O/W emulsion extracted from tertiary oil recovery (especially alkaline flooding, surfactant flooding, etc.) is stabilized by water-soluble surfactants or water wet solid particles (such as clay particles). Due to the water content and increased volume of emulsified crude oil, the load on pumps, storage tanks, and pipelines increases, and it also exacerbates corrosion and scaling on the inner surface of metal pipelines. Therefore, before export it is necessary to demulsify and dehydrate the crude oil.   The methods of demulsification include electrical, thermal, and chemical methods, but in practical processes, several methods are often used in combination.The basic principle of demulsification of crude oil emulsions is as follows: (1) The demulsifier replaces the emulsifier at the droplet interface of the emulsion, forming a membrane with poor structural strength, greatly reducing the stability of the emulsion. (2) Choose a surfactant with an HLB value opposite to that of the crude oil emulsifier as the demulsifier, such as a W/O emulsifier with an HLB value of 3-6. The HLB value of the selected demulsifier should be 12-16. Through their different emulsifying effects, the emulsion is demulsified.   The main uses of emulsifiers include Dodecyl trimethyl ammonium chloride, Tetradecyl trimethyl ammonium chloride, Didecyl dimethyl ammonium chloride, and most quaternary ammonium salts, which are all the strong products of Ahsuperchem. They can be used to break down stable O/W emulsions formed by anionic surfactants such as hydrophilic carboxylate salts, sulfonates, sulfates, and wet clay. The electrostatic neutralization effect of cationic surfactants on the surface of oil droplets is the basis for their emulsion breaking. After neutralization, the electrostatic repulsion between oil droplets decreases, while the collision and coalescence probability between oil droplets increases, which deteriorates the stability of the emulsion and achieves the purpose of emulsion breaking and oil-water separation. Polycationic polymer surfactants not only have electrostatic neutralization effect on oil droplets during the demulsification process, but also have a certain coagulation effect, thereby improving the oil removal efficiency. Quaternary ammonium salt cationic surfactants with lower relative molecular weight have excellent demulsification performance.

Quaternary ammonium salt disinfectant is a new type of disinfectant that has received widespread attention and application in recent years due to its high efficiency, safety, low toxicity, and environmental protection characteristics. With the continuous improvement of people's awareness of health and environmental protection, the market prospects of quaternary ammonium salt disinfectants are also becoming increasingly broad. Firstly, with the continuous intensification of the global epidemic, the demand for disinfectants is constantly increasing. The efficient bactericidal ability of quaternary ammonium salt disinfectants has made them an important disinfectant in industries such as hospitals, laboratories, and food processing. Meanwhile, with the increasing demand for disinfectants in people's daily lives, quaternary ammonium salt disinfectants will gradually enter thousands of households. Secondly, with the continuous improvement of people's awareness of environmental protection and health, the requirements for the safety and environmental friendliness of disinfectants are also increasing. The low toxicity and environmental friendliness of quaternary ammonium salt disinfectants have made them increasingly popular as environmentally friendly disinfectants. At the same time, as the government's support for the environmental protection industry continues to increase, the market prospects of quaternary ammonium salt disinfectants will also become increasingly broad. Finally, with the continuous progress and innovation of technology, the application fields of quaternary ammonium salt disinfectants are also expanding. For example, quaternary ammonium salt disinfectants can be used for disinfection of medical devices, sanitary ware, surface environments, and other aspects, and can be applied in more fields in the future. In summary, the market prospects of quaternary ammonium salt disinfectants are very broad.   Ahsuperchem supply Didecyl dimethyl ammonium chloride (DDAC) and Benzalkonium chloride (BKC), which are widely used as the raw materials for disinfectants.
