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 use of 1,3-butadiene as a cheap and abundant raw material for new applications has attracted more interest in recent decades, specifically in the chemical industry. The review covers several ...

The objective of the present study was to investigate 1-methyl 1, 2, 3, 4-tetrahydroisoquinoline (1MeTIQ), an endogenous amine found in human brain with a known neuroprotective profile, in a model of ...

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 ...

uab.edu Objective To evaluate exposure–response between 1,3-butadiene ... Results Among 21 087 workers, adjusted RRs for butadiene and all leukaemia (132 deaths) rose with increasing exposure, with an ...
