- Reductive dimerization and oligomerization of alcohols, ketones, and aldehydes to hydrocarbons on a promoted, fused iron catalyst
-
A new reductive dimerization and oligomerization reaction of (C5 and C6) cycloalkanols and cycloalkanones, benzaldehyde, and benzyl alcohol to hydrocarbons containing as many, or more, carbon atoms as the reactant oxygenated compound on a promoted, fused iron catalyst proceeds at a temperature of 250-350°C, a hydrogen pressure of 0.1-1 MPa, a specific feed rate of oxygenated reagent of 80-320 g h-1kg-1Ct, and a hydrogen space velocity of 1 × 103 to 20 × 103 h-1. Possible reaction mechanisms have been considered.

- New one-pot multistep process with multifunctional catalysts: Decreasing the e factor in the synthesis of fine chemicals
-
The synthesis of a series of fine chemicals (4-(4-methoxyphenyl)-2- butanone, 4-(6,6-dimethylbicyclo[3,1,1]hept-2-en-2-yl)-2-butanone, and 2-cyclopentylcylopentanone) has been performed through a simple process that involves one-pot multi-step reactions (condensation-dehydration-reduction) using multifunctional base-acid-metal catalysts. The E factor for the specific process, as well as for the global process that includes the manufacturing of the reactants, has been calculated and compared with those obtained using conventional methods. In various cases, it is demonstrated that by means of process intensification with multifunctional solid catalysts, it is possible to decrease the E factor by one order of magnitude or more with respect to any of the manufacturing routes reported to date.
