The product we are introducing is High Quality Trifluoromethanesulfonimide with the CAS number 82113 - 65 - 3. Trifluoromethanesulfonimide, also known as bis(trifluoromethanesulfonyl)imide, is a white crystalline solid. It has a high melting point and good thermal stability. In terms of chemical properties, it is a strong acid due to the electron - withdrawing effect of the trifluoromethyl groups. The molecular formula of trifluoromethanesulfonimide is C2HF6NO4S2, and its molecular weight is approximately 281.15 g/mol. It is usually supplied in high - purity forms to meet the strict requirements of various industries.
Trifluoromethanesulfonimide has a wide range of applications in different fields. In the field of electrochemistry, it is commonly used as an electrolyte additive in lithium - ion batteries. It can improve the conductivity of the electrolyte, enhance the cycling performance of the battery, and increase the battery's stability at high voltages. In organic synthesis, it serves as a powerful catalyst. It can catalyze many important organic reactions, such as Friedel - Crafts reactions, Diels - Alder reactions, and esterification reactions. Its strong acidity and unique chemical structure make it an ideal catalyst for promoting these reactions under mild conditions. Additionally, in the field of materials science, trifluoromethanesulfonimide is used to modify polymers. It can improve the surface properties of polymers, such as increasing their hydrophobicity and chemical resistance.
When using trifluoromethanesulfonimide, it is crucial to follow proper safety procedures. Wear appropriate personal protective equipment, including gloves, goggles, and a lab coat. In the laboratory or industrial setting, handle the product in a well - ventilated area to prevent inhalation of dust or fumes. For its use in electrochemistry, when preparing the electrolyte, add the appropriate amount of trifluoromethanesulfonimide to the base electrolyte solvent. Stir the mixture thoroughly until the additive is completely dissolved. The concentration of the additive should be carefully controlled according to the specific requirements of the battery system. In organic synthesis, add the trifluoromethanesulfonimide catalyst to the reaction mixture at the appropriate stage of the reaction. The amount of catalyst needed depends on the type and scale of the reaction. Usually, a small amount of the catalyst can significantly promote the reaction rate.
Case 1: Lithium - Ion Battery Application
A research team was working on improving the performance of a lithium - ion battery for electric vehicles. They added a certain amount of trifluoromethanesulfonimide to the electrolyte of the battery. After a series of tests, they found that the battery's initial charge - discharge efficiency increased from 85% to 92%. The cycling performance was also greatly improved. After 500 charge - discharge cycles, the capacity retention rate of the battery with the additive was 80%, while the battery without the additive was only 60%.
Caso 2: Síntesis orgánica
A chemical company was synthesizing a new drug intermediate through a Friedel - Crafts reaction. They used trifluoromethanesulfonimide as a catalyst. The reaction time was significantly reduced from 24 hours to 6 hours, and the yield of the product increased from 60% to 85%. This not only saved production time but also reduced production costs.
