制备方法与用途

概述

硬脂酰苯甲酰甲烷(SBM)是一种重要的β-二酮结构的塑料用辅助热稳定剂。它能够与多种稳定剂复合使用,通过组分之间的协同作用,有效改善聚氯乙烯制品的透明性、耐候性,并避免加工过程中的析出和“锌烧”现象。

特点

硬脂酰苯甲酰甲烷相较于常用稳定剂,具有良好的热稳定性、化学稳定性和光稳定性。此外,它无毒无味且不污染制品,因此被广泛应用于食品和医药包装领域,如矿泉水瓶、油瓶、透明片材和透明薄膜等。

用途

作为钙/锌羟酸盐稳定体系的共稳定剂,硬脂酰苯甲酰甲烷可用于制造矿泉水瓶、油桶、透明片材和透明薄膜。同时,它也可用作有机PVC辅助热稳定剂,主要配合复合钙锌/复合稀土类热稳定剂使用,能够抑制初期着色,防止“锌烧”,并提高PVC制品的热稳定性。

    required to facilitate the dehydrogenation and dehydration processes. The key factor in the success was the use of n Bu 4 NBF 4 as the electrolyte and hexafluoroisopropanol (HFIP) as the solvent, which play key roles in the cyclocondensation step. This electrolysis is scalable and can be used as a key step in drug synthesis. On the basis of the several experimental results, the mechanism, particularly
    制备电化学合成是建立绿色可持续工艺的理想方法。与传统的化学合成方法相比,有机化学策略的主要优点是避免了试剂浪费和温和的反应条件。在此,已经开发了在不分开的电解条件下,酚与β-二羰基化合物之间的分子间交叉脱氢偶联(CDC),以构建各种苯并呋喃。过渡金属或外部化学氧化剂都不需要以促进脱氢和脱水过程。成功的关键因素是使用n Bu 4 NBF 4作为电解质,使用六氟异丙醇(HFIP)作为溶剂,它们在环缩合步骤中起关键作用。这种电解是可扩展的,可以用作药物合成中的关键步骤。
