Defatted rice bran is a promising biomass residue comprises of furfural, a desirable intermediate bioplatform chemical acts as a potential raw material aims for sustainable production of value added chemicals and also for generating renewable fuels, as an alternative source of energy to fossil fuel. The main focus of the work is to develop novel microwave assisted synthetic approach which is one of the greener and eco-friendly method for the conversion of furfural to produce value-added products through in-situ acetalisation reaction with glycerol in presence of hydrogen peroxide as oxidizer. Many researchers have begun exploring new uses for glycerol, including its conversion to fuel additives, due to the overproduction of glycerol as byproduct from bio-refineries. In this paper, glycerol a renewable waste substrate obtained in excess has been reacted with furfural to yield the corresponding acetal and value added chemicals such as carboxylic acids, esters, aldehydes, dienes, amides, ketones, alcohols, cycloalkanes and so on confirmed by GC-MS analysis. This microwave assisted in-situ acetalisation reaction synthesis with different molar ratios of glycerol and minimal amount of 30%H2O2 solvent leads to highly energy efficient, low cost and eco-friendly process carried out under optimum conditions with variation of reaction time and temperature has profound influence on the reaction rate, product yield and percentage conversion. These value-added chemicals used as fuel additive and have wide applications in polymer, agrochemical and pharmaceutical industries.
