Chlorohydrin processing equipment comprising stainless steel

摘要

The present invention provides a process for the production of chlorohydrins, comprising generating a chlorohydrins processing stream and contacting at least a portion of a surface comprising a austenitic stainless steel with the chlorohydrin processing stream. It has now been surprisingly discovered that certain stainless steels can be utilized to form portions, or the entirety of, one or more pieces of processing equipment utilized in such processes.
