Abstract
A carbon supported solid catalyst suitable for the vapor phase carbonylation of lower aliphatic alcohols, ethers, ester, and ester-alcohol mixtures, and desirably, methanol, to produce carboxylic acid, esters and mixtures thereof. The solid supported catalyst includes an effective amount of iridium and gold associated with a solid carbon support, and a halogen promoter. The halogen promoter component of the catalyst is preferably vaporous, thus providing a two-phase catalyst system,
