Process for removing trace amounts of epichlorohydrin from heat sensitive glycidyl products

摘要

Epichlorohydrin levels in heat sensitive glycidyl products are reduced from a few thousand ppm, an unacceptable level, to only a few ppm or to a non-detectable level by use of a multistage stripping column with or without inert gas purging without decomposition of the heat sensitive glycidyl products. Such glycidyl products are useful in epoxy resins particularly as crosslinking agents.
