Formation of acetaldehydenext term via photocarbonylation of methane with CO

Description:

This is a possible reaction path and method for methane + CO to acetaldehyde.  The yield was very small, but it was carried out at or very close to STP.  This reaction is thermo-favorable at ~4000 atm, but the use of UV light appears to have potential for lowering the severity of conditions.

  1. Here is the quick summary I wrote about this article:

    This article details a reaction path using methane and carbon monoxide dissolved in benzene and exposed to UV irradiation. The reaction is accelerated in the presence of a Vaska type rhodium complex, especially with [RhCl(CO)(P(C6H11)3)2], which gives conversion rates of 3.7% CH4 and 21% CO (In a 1:8 mixture of CO/CH4). Also produces about 1 mmol of benzaldehyde for every 10 mmol of acetaldehyde produced.
