Process for stabilizing methyleneimine compound and stabilized methyleneimine composition.

摘要

A cyclohexylmethyleneimine compound represented by the following general formula:
<Chemistry id="chema01" num="0001"><Image id="ia01" he="19" wi="36" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein R is an alkyl group bonded to individual carbon atom of the cyclohexyl ring and n is an integer of 0 to 5, or a methyleneimine composition containing at least the cyc- tohexylmethyleneimine compound can be stabilized by an organic lithium compound represented by the following general formula:
<Chemistry id="chema02" num="0002"><Image id="ia02" he="8" wi="39" file="IMGA0002.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein R' is an alkyl, aryl, or aralkyl group, and can be preserved stably for a long time.
