ConditionsYieldWith potassium hydroxide In acetonitrile at 55℃; for 13h; Cooling with ice;Experimental Procedure2 Example 2Put potassium hydroxide (7.954g) and sodium tetrafluoroborate (19.069g) into a two-necked round bottom flask containing 120ml of anhydrous acetonitrile, add 1,4-dichlorobutane (12.56g) under stirring, and finally Add dimethylamine (5.23g) dropwise to the above solution under ice bath conditions (the dripping time is 0.5h). After the dripping is completed, the reaction solution is stirred for 1h to uniformity, and the heating is turned on and the temperature is raised to 55°C for 12h to react. After completion, the reaction solution was returned to room temperature (20°C). The solvent in the reaction solution was removed from the above reaction solution by a rotary evaporator to obtain a powder-solid mixture. 50ml of absolute ethanol was added to the powder-solid mixture and stirred at 50°C for 1 hour. After cooling to room temperature, the impurity salt was removed by filtration to obtain an ethanol solution of N,N-dimethylpyrrolidinium tetrafluoroborate. The ethanol solution of N,N-dimethylpyrrolidinium tetrafluoroborate Recrystallize at low temperature (-20), then filter to obtain high-purity N,N-dimethylpyrrolidinium tetrafluoroborate, repeat recrystallization three times to obtain pure N,N-dimethyl Pyrrolidinium tetrafluoroborate, ethanol used for recrystallization is recovered for recrystallization of the next batch of materials. The obtained pure N,N-dimethylpyrrolidinium tetrafluoroborate was dried under vacuum at 110 for 12h to obtain dry pure N,N-dimethylpyrrolidinium tetrafluoroborate. Statistics , The yield is 91%.91%

BCB (Benzocyclobutene): — Watson International Enables the Transition from Concept to Scalable Application

Benzocyclobutene (BCB) is an organic compound with a rigid molecular structure composed of a conjugated benzene ring and a four-membered ring. Its excellent thermal stability and electrical properties have made it a highly promising candidate for next-generation electronic materials. Historically, its industrial adoption has been constrained by high production costs, complex purification processes, and limited output. However, with growing demand in high-end applications and recent advances in upstream technology, BCB is now poised for industrial-scale deployment. Material Properties and Structural Advantages BCB (C₈H₈) is a non-polar molecule, free of ester, carboxyl, or amide groups, giving it excellent dielectric properties and low moisture absorption. Its dielectric constant (Dk) and dissipation factor (Df) remain stable across wide temperature and frequency ranges—key metrics for ensuring signal integrity in high-frequency, high-speed communication systems. Unlike conventional m...
