High-performance biocomposites, biopolymers, bioexplosives, and bioadhesives made from biomesitylene

摘要

A biomass is used to prepare bio-acetone which is converted to bio-mesitylene in high chemical yield and selectivity and the latter is converted using continuous flow chemical processes to a variety of functionalized bioaromatics that are useful in the preparation of high performance biopolymers, biocomposites, bio-explosives, and bio-adhesives.

主权项

1. A method for preparing bio-mesitylene from biomass, comprising:
treating a biomass with an aqueous solution or extraction media and an acid catalyst to produce a mixture of hemi-cellulosic and cellulosic sugars; fermenting said mixture of sugars utilizing at least one bio-organism to a fermentation broth having n-butanol, acetone, and ethanol; stripping said acetone from said fermentation broth by sparging with a gas and condensed to forming a liquid substantially having acetone; contacting said acetone with a heat treated solid supported dehydration-cyclotrimerization catalyst treated with arylsilanes, arylsiloxanes, alkylsilanes, and/or alkylsiloxanes for a period of 1 to about 500 seconds at pressures ranging from about 0.02 psig (1 torr to about 1000 psig, wherein said supported catalyst is prepared from based treated aluminum and/or silicon oxide support and having from 0.1 to 5 wt-% of a Group 5 metal oxide dispersed over said aluminum and/or silicon oxide support; and collecting said bio-mesitylene and purifying said bio-mesitylene by fractionation.
