新型辅助稳定剂β-二酮的研制

Study and Synthesis of A Novel Assistant Stabilizer β- Diketone

主要研究采用硬脂酸甲酯和苯乙酮在强碱类催化剂作用下制备β-二酮化合物之一的硬脂酰苯甲酰甲烷的最佳配方和适宜的工艺条件。制取的产品经核磁共振官能团测定和进口标准品一致,经流变仪上加工性能测定优于国内同类产品。

The study mainly aims at the optima composition and suitable technological conditions of stearoylbenzoyl-methane--one of the β- diketone compounds prepared from methyl stearate and phenyl ethyl ketone under alkaline catalysts. The NMR functional group determination of the prepared product agreed with that of the imported standard product, the processability determined by rheometer is better than that of the same domestic products.
