Abstract
A process and apparatus to enable the continuous isolation of an organometallic compound, such as trimethylindium from a liquid feedstock. The liquid feedstock is delivered to a distillation column having two heating zones to effect dissociation of the feed stock thereby liberating the organometallic compound, which is collected as a vapor from the top of the column.
