Specifications :

Usage：

• Advanced Battery Electrolyte Solvent (Core Absolute Application): Serves as a premier aprotic polar solvent across next-generation energy storage technology.

  • Electrolyte Formulation: Widely used in electrolyte systems for standard and solid-state/semi-solid-state batteries. Its exceptional metal-ion solvating ability and wide electrochemical stability window significantly enhance battery cycle life and rate performance.

• Gas Scrubbing & Acid Gas Removal: Due to its high selective solubility for acidic gases, it serves as an efficient absorbent (acid gas removal agent) for natural gas, syngas, and refinery gas.

• Aprotic Solvent for Organometallic Chemistry: As a highly polar aprotic solvent, it is widely used in Grignard reactions, lithium aluminum hydride reductions, metal alkylations, and phase-transfer catalysis systems, effectively improving reaction yields.

• Specialty Cleaning & Coating Auxiliary: Applied in semiconductor manufacturing as a precision cleaning fluid, photoresist stripper component, and high-boiling resin plasticizer.

Storage:

Must be stored in a cool, dry, dark, and well-ventilated dedicated chemical warehouse.

Keep away from heat sources and open flames; suggested storage temperatures should not exceed 30°C.

Keep containers hermetically sealed, nitrogen-blanketed, and protected from humidity/light.

Strictly avoid joint storage alongside powerful oxidizers or mineral acids.
