A new route to synthesize tert-butyl ethers of bioglycerol

Alternative fuel additives from glycerol by etherification with isobutene: Structure–performance relationships in solid catalysts

“…The growing biodiesel industry would provide crude and refined glycerol as an abundant, sustainable, non-toxic and inexpensive raw material for the value-added products from glycerol [68,81,139]. Utilization of biodiesel derived glycerol is expected to reduce biodiesel prices and to stabilize glycerol prices at low values [1,2,14,20,22,85,[140][141][142][143].…”

Glycerol-free biodiesel production through transesterification: a review

“…This greatly influenced the revenue from biodiesel production plants [12] because of the lower income due to glycerine sales. This initiated research into the use of crude and purified glycerol as feedstock for bio-chemicals production [13][14][15][16][17][18]. Reported conversions were however relatively low, and the expensive biocatalyst necessary to convert crude glycerol to high value products pushed research into the direction of trying to eliminate the formation of glycerol during the reaction.…”

Properties of fatty acid glycerol formal ester (FAGE) for use as a component in blends for diesel engines

“…This product can also be produced by direct acetylation (or esterification) of glycerol with acetic acid [13e15], with acetic anhydride [11,16] or with acetyl chloride [16]. Etherification of glycerol either with isobutylene [17,18], with tert-butyl alcohol [18,19], with ethanol [20] or through other processes [21,22], is another promising way to produce mono-, di-or tri-tert-butyl ethers (or ethyl ethers), which can also be useful as oxygenated additives. Some of these ethers have also shown certain effectiveness in particulate matter suppression in diesel engines [23].…”
