Quantitative characterization of acetylation degree of phenolic hydroxyl compounds synthesized from thermally induced liquid crystal polymers (TLCP) using nuclear magnetic hydrogen spectroscopy
This study focuses on the acetylation process of two phenolic hydroxyl monomers, PHBA and BP. The composition of the acetylation products was analyzed by nuclear magnetic resonance hydrogen spectroscopy, and the effects of catalyst type, dosage, acetylation time, and acylation agent dosage on the degree of acetylation and product composition were explored. This provides a theoretical basis for optimizing the synthesis process of TLCP.

Full analysis of temperature rise test for power battery control unit: How to maintain thermal runaway defense line under high voltage overcurrent?
In practical use, BCU may face extreme conditions of high voltage overcurrent, such as battery pack short circuit or charging equipment failure, resulting in abnormal current rise. In this case, the components inside the BCU will generate a large amount of heat due to excessive current, which may cause a sharp rise in temperature, thereby affecting its performance and lifespan, and even causing safety hazards.
