US Patent:

53549163, Oct 11, 1994

Filed:

Jan 24, 1994

Appl. No.:

8/187351

Inventors:

Istvan T. Horvath - New Hope PA
John M. Millar - Summit NJ
Raymond A. Cook - Hampton NJ

Assignee:

Exxon Research and Engineering Company - Florham Park NJ

International Classification:

C07C 2958
C07C 1710

US Classification:

568893

Abstract:

The invention relates to a process for selectively producing alkyl halides from alkanes, such as methane and ethane at low temperatures and low pressures. Optional hydrolysis to the corresponding alcohols may follow. The process involves adding an alkane and an added halogen source to an aqueous solution in a homogeneous system in the presence of a transition metal halide containing complex, for a time, under conditions and in effective amounts that will permit the formation of alkyl monohalides.

US Classification:

568454

Abstract:

The invention is a process for hydroformylating multicomponent syngas feed streams containing CO, H. sub. 2, C. sub. 2 to C. sub. 5 olefins and mixtures thereof and C. sub. 2 to C. sub. 5 alkynes and mixtures thereof by contacting the multicomponent syngas feed stream with a solution of an oil soluble rhodium complex catalyst produced by complexing in solution a low valence Rh and an oil soluble triorganophoshorous compound wherein the catalyst has a P/Rh ratio of at least 30, a concentration of Rh in solution from about 1 to about 1000 ppm by weight, a total concentration of coordinatively active P of at least about 0. 01 mol/l, and a ratio of [P]/p. sub. co of at least 0. 1 mmol/l/kPa, wherein [P] is the total concentration of coordinatively active phosphorous in the solution, and p. sub. co is the partial pressure of CO, to produce the corresponding C. sub. 3 to C. sub. 6 aldehydes.
