dissolved in 1-butyl-3-methyl imidazolium tetrafluoroborate (1), trifluoromethanesulphonate (2) or hexafluorophosphate (3) catalyze the reduction of 1,3-butadiene into butenes in a typical two-phase ...

A decrease in the trans/cis 2-butene ratio was observed after reduction at 773 K. Selectivity changes were ascribed to the decoration model. Theoretical models were developed based on semi-empirical ...

Siam Cement Public has patented a catalyst for converting ethanol to 1,3-butadiene. The catalyst includes zeolite, silicon dioxide, or aluminum oxide as component A, and a mixed metal oxide as ...

Here, we evaluate the effects of two ETS components on plaque development: the vapor phase component, 1,3 butadiene, and the tar component ... at a dose that is environmentally relevant. (2) The ...

The 3-2-1 method is still going strong in 2025. Here are a few reasons why it has withstood the test of time: If you're interested in the 3-2-1 method, Van Rensburg recommends starting simple ...

1,3-butadiene is used mainly in the production of synthetic rubbers and polymers. Workplace concentrations in Canada, the USA, and western Europe, are generally below 2 mg/m 3, but can be higher in ...
