Abstract

Abstract The increase in biodiesel production has resulted in the oversupply of glycerol into the market. Purified and processed glycerol has found many direct applications in pharmaceuticals, food, etc. However, the cost of processing and market value of processed glycerol has driven the research of direct utilization of crude glycerol to industrially essential chemicals. Various methods and research have been devoted to using glycerol to produce value-added products separately. Glycerol can undergo several transformation reactions like hydrogenation, oxidation, alcoholysis, and etherification. Etherification of glycerol can be divided into three main reactions: self-etherification, using alcohol, and olefins and these products have vast applications such as fuel additives, plasticizer, etc. The current review presents a comprehensive summary of glycerol etherification to value-added products and their applications. The catalytic system developed along with reaction conditions and the factors responsible for the better activity is also discussed. Overall, the review presents a detailed discussion on the catalytic system developed, the utilization of different alcohols and olefins, and the application of products. Moreover, the environmental and economic aspects of the etherification of glycerol via various conversion routes while assessing the process parameters needs to be tackled to attain wider adoption of the process.

甘油催化醚化制高附加值产品综述

摘要生物柴油产量的增加导致市场上甘油供应过剩。纯化和加工的甘油在制药、食品等领域有许多直接应用。然而，加工成本和加工甘油的市场价值推动了将粗甘油直接用作工业必需化学品的研究。利用甘油单独生产增值产品的方法和研究多种多样。甘油可以经历几个转化反应，如氢化、氧化、醇解和醚化。甘油醚化可分为三个主要反应：自醚化、利用醇和烯烃，这些产物在燃料添加剂、增塑剂等方面有着广泛的应用。还讨论了随着反应条件的发展而形成的催化体系以及产生更好活性的因素。总的来说，该综述对所开发的催化体系、不同醇和烯烃的利用以及产品的应用进行了详细的讨论。此外，在评估工艺参数的同时，需要解决甘油通过各种转化途径醚化的环境和经济方面的问题，以实现该工艺的更广泛采用。
