Abstract
A highly efficient method of producing dialkyl disulfides from mercaptans and oxygen is described which involves employing carbon dioxide as an internal coolant. Among the benefits made possible by this method are (1) an increase in the proportion of mercaptan converted to dialkyl disulfide per pass through the reactor, (2) an increased ease of separation of and recycling of carbon dioxide, (3) the ability to use a common contaminant as a coolant, and (4) the use of a simple adiabatic reactor design.
