Dehydration of 2,3-butanediol to methyl ethyl ketone in sub- and supercritical water

چکیده
Polyols can be synthesized from carbohydrates in bioor chemo-catalytic way. The conversion of polyols with two hydroxyl groups in 1,4-positions, for example 1,4-butanediol, results in furan derivatives. In contrast, during the dehydration of diols with two vicinal hydroxyl groups, for example, 1,2-propaneand 1,2-butanediol, aldehydes or ketones are formed [1] . This will be presented exemplarily with the dehydration of 2,3-butanediol into methyl ethyl ketone. 2,3-butandiol is fermentative available from carbohydrates such as hexoses and pentoses or from lignocellulosic wastes [2] . The reaction in water allows to directly convert the fermentative available 2,3-butanediol solution into methyl ethyl ketone without water separation.

One-Step Production of 1,3-Butadiene from 2,3-Butanediol Dehydration.
We report the direct production of 1,3-butadiene from the dehydration of 2,3-butandiol by using alumina as catalyst. Under optimized kinetic reaction conditions, the production of methyl ethyl ketone and isobutyraldehyde, formed via the pinacol-pinacolone rearrangement, was markedly reduced and almost 80 % selectivity to 1,3-butadiene and 1,3-butadiene could be achieved. The presence of water p...

A 1D heterogeneous reactor model accounting for interfacial and intra-particle gradients was developed to simulate the dehydration of 2,3-Butanediol (2,3-BDO) to 1,3-Butadiene (1,3-BD) and Methyl Ethyl Ketone (MEK) over an amorphous calcium phosphate (a-CP) catalyst in a pilot-scale fixed-bed reactor. The developed model was validated with experimental data in terms of a fluid temperature profi...

The kinetics of inhaled methyl ethyl ketone (MEK) at a concentration of 200 ppm for four hours were studied in volunteers after swallowing ethanol at a dose of 0.8 g/kg. Ethanol was given either before or at the end of the exposure to MEK. The blood concentrations of MEK, 2-butanol, and 2,3-butanediol were monitored during and after the exposure. MEK concentrations in exhaled air and MEK and 2,...
