Processes are disclosed for the oxidation of alkanes such as, for example, propane, to form unsaturated carboxylic aldehydes and acids such as, for example, acrolein and acrylic acid. The processes utilize oxygen and recycle alkanes, e.g. propane, to the aldehyde reactor. The presence of the alkane-to-aldehyde reaction can enhance the efficiency of the processes.

Process for the oxidation of alkanes

Processes are disclosed for the conversion of propylene to an acrolein derivative by converting propylene to acrolein and converting acrolein to the acrolein derivative. The processes utilize oxygen and recycle propane to the acrolein reactor. Process feeds can comprise, propane, propylene or mixtures thereof. The presence of propane in the propylene-to-acrolein reaction can enhance the efficiency of the processes.

Processes for the manufacture of acrolein derivatives

Processes are disclosed for the conversion of propylene to acrolein in the presence of propane. The processes utilize oxygen and recycle propane to the acrolein reactor. Process feeds can comprise, propane, propylene or mixtures thereof. The presence of propane in the propylene-to-acrolein reaction can enhance the efficiency of the processes.

Processes for the manufacture of methylmercaptopropanal

Oxidative coupling of lower alkane to higher hydrocarbon is conducted using catalyst comprising barium and/or strontium component and a metal oxide combustion promoter in the presence of vapor phase halogen component. High ethylene to ethane mole ratios in the product can be obtained over extended operating periods.

High ethylene to ethane processes for oxidative coupling

Volatilized metal compounds retard vapor phase alkane conversion reactions in oxidative coupling processes that convert lower alkanes to higher hydrocarbons.

Vapor phase modifiers for oxidative coupling

Alkanols are selectively produced as the major product directly from synthesis gas under mild conditions using a homogeneous ruthenium catalyst, a halogen or halide promoter and a phosphine oxide compound as solvent.
