Abstract Bio-based lubricants are an attractive class of products, gaining more attention in the recent years. The production of bio-based lubricants starting from vegetable oils derivates (e.g. epoxidized) and alcohols is gaining relevance among the various synthetic routes. Broensted acids are normally used to promote the oxirane ring opening reaction, obtaining interesting products depending on the branching and chain length of the alcohol molecule. The use of homogeneous catalysts leads to evident drawbacks that could be overcome by replacing them with heterogeneous catalysts. Clays can be considered good candidates as they show reasonable acidity and are characterized by high availability and low price. In the present paper, the use of TONSIL EX 2166 was demonstrated to be a good candidate for the synthesis of bio-lubricant bases in the presence of 2-butanol. A kinetic model was proposed to describe the physical and chemical phenomena occurring in the reaction network.

由粘土促进的环氧化油合成生物润滑剂：动力学建模

摘要 生物基润滑剂是一类极具吸引力的产品，近年来受到越来越多的关注。从植物油衍生物（例如环氧化）和醇开始生产生物基润滑剂在各种合成路线中越来越重要。布朗斯台德酸通常用于促进环氧乙烷开环反应，根据醇分子的支链和链长获得有趣的产物。使用均相催化剂会导致明显的缺点，可以通过用非均相催化剂代替它们来克服这些缺点。粘土可以被认为是很好的候选者，因为它们显示出合理的酸度，并且具有高可用性和低价格的特点。在本文中，使用 TONSIL EX 2166 被证明是在 2-丁醇存在下合成生物润滑剂基质的良好候选者。提出了一个动力学模型来描述反应网络中发生的物理和化学现象。
