While stirring, 120.2 g (0.47 mol, 1 .2 equivalents) of ethylaluminium sesquichloride (Et3AI2Cl3) are added in such a way that the temperature in the reaction mixture does not exceed 120°C. The reaction mixture is subsequently heated while applying a reduced pressure of 300 mbar, and Et3Ga is thus isolated (46.6 g; direct yield 75.9%). A 75.9%B 19%

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...
