Solvent effects in the hydrogenation of 2-butanone - ScienceDirect

1/5/2012· For example, a minimum in the rate of 2-butene-1,4-diol hydrogenation (the second step in the hydrogenation of 2-butyne-1,4-diol over Pd/Al 2 O 3) occurred at 80–90 mol H2O % in a 2-propanol/water solvent [7]. Elsewhere, an enhancement in the rate of reaction in mixed alcohol/water solvents as compared to the pure alcohol has been observed in

Startup Business Investment in Butanone Industry. MEK vs. Acetone MEK and acetone are both used as industrial solvents for stripping and cleaning uncured and cured resins and coatings, and for cleaning pumps and other equipment. Since MEK is a slightly harsher chemical, some choose to replace MEK with acetone as a “safer” alternative.

Butanone - an overview ScienceDirect Topics

The best candidate in this case is 2- Butanone (methyl-ethyl-ketone : MEK) with vacuum operation of the distillation column. Although 2-Butanone offers relatively low water flux, it is selected because the energy requirement to satisfy the purity standard is less than the half of the 2nd best candidate, ammonium hydroxide.
