Abstract
The invention is a method of removing methyl iodide from an alkane distillation bottoms stream of an acetic acid production process. The method comprises contacting the alkane distillation bottoms stream in the liquid phase with a phosphine or a phosphine-functionalized support, and recovering a treated alkane distillation bottoms stream having a reduced methyl iodide content.
