An attractive route for the production of these NIPUs is the carbonation of epoxidized vegetable oils. As illustrated by Fig. 1, the production route is greener, and CO 2 and biomass materials are used. It can be noticed that the production of epoxidized and carbonated vegetable oils are the key intermediates during this process.

Green approach for the preparation of biodegradable lubricant base
A novel process for the production of biodegradable lubricant-based stocks from epoxidized vegetable oil with a lower pour point via cationic ion-exchange resins as catalysts was developed. This involves two steps, first, ring-opening reactions by alcoholysis followed by esterification of the resultant hydroxy group in the first step.

Sustainable Series of New Epoxidized Vegetable Oil-Based Thermosets
This work reports for the first time the copolymerization studies of 11 newly synthesized epoxidized vegetable oils (EVOs) that reacted with a disulfide-based aromatic dicarboxylic acid (DCA) to produce thermoset materials with recyclability properties. These new EVOs¡¯ reactivity and properties were compared with those of the two commercial references: epoxidized linseed oil (ELO) and

Vegetable oils as bio-based precursors for epoxies
Abstract. Epoxy is widely used in industry and has a wide range of applications, including material coating, electronics, adhesives, and fiber-reinforced plastics, but its production from fossil fuels pollutes the environment. Epoxidized vegetable oils (EVOs) are a strong contender to replace epoxy products made from fossil fuels because they

RECENT ADVANCES IN EPOXIDATION OF VEGETABLE OILS - JETIR
The world production of major vegetable oils has risen from 95 million tonnes in 2002/2003 to 154 million tonnes in 2012/2013 at an average rate just over 5 million tonnes a year. Majority of vegetable oils are produced for domestic purposes while a few minor vegetable oils like linseed oil and castor are used for industrial purposes.

Highly efficient epoxidation of vegetable oils ... - RSC Publishing
Epoxidized vegetable oils (EVOs) are versatile building blocks for lubricants, plasticizers, polyvinyl chloride (PVC) stabilizers, and surface coating formulations. In this paper, a catalytic protocol for the efficient epoxidation of vegetable oils is presented that is based on a combination of a manganese catalyst, H 2 O 2 as an oxidant, and acetic acid as an additive.
