Cyclic Carbonates Based on Vegetable Oils

Abstract

The analysis of literary data on the obtaining of cyclic carbonates based on the vegetable oils has been carried out. The influence on carbonation reaction the type of vegetable oil, the chemical composition and catalyst concentration, state of carbon dioxide, pressure and temperature have thus been considered. The carbonation process of epoxidized oils that are valuable renewable vegetable raw materials is studied insufficiently.

From the Synthesis of Biobased Cyclic Carbonate to Polyhydroxyurethanes: A Promising Route towards Renewable Non‐Isocyanate Polyurethanes

“…Carbonation of EVO is always performed with CO 2 , in the gaseous or supercritical state. The EVO carbonation process has been recently reviewed . Even if oxiranes are highly reactive groups, their position inside the triglyceride chains can induce steric hindrance and considerably reduce the conversion of epoxy compounds into carbonates.…”

To promote the reaction, TBABr is widely used Scheme8.Progression from plant-based biomass to building blocks and end materials.…”

A novel 2,5-furandicarboxylic acid-based bis(cyclic carbonate) for the synthesis of biobased non-isocyanate polyurethanes

“…Most of the currently available biobased PHUs are derived from vegetable oils, especially soybean oil and linseed oil. 11,16 Vegetable oils are fatty acid triglycerides with various degrees of unsaturation which can be epoxidized by a peroxide or a peracid. Epoxidized vegetable oils can further react with CO 2 to yield vegetable oil-derived poly(cyclic carbonate)s. Eventually, biobased PHUs can be synthesized by the reaction between these poly(cyclic carbonate)s and diamines or triamines.…”

Organocatalytic synthesis of bio-based cyclic carbonates from CO2 and vegetable oils

“…Besides, the synthesis of bio-based cyclic carbonates from CO2 and epoxidized vegetables oils is a subject of growing interest that allows the synthesis of fully bio-based chemicals. However, the identification and development of efficient (organo)catalysts for synthesizing cyclic carbonates from biobased epoxides still remains challenging [14] . At the exception of Rokicki's work [15] , coupling of CO2 with vernonia oil (a naturally epoxy functionalized triglyceride) or epoxidized soybean, linseed or cotton oils was only promoted by tetrabutylammonium bromide (TBABr).…”
