On the inhibition of the HDN of anilines due to quinolines

The decomposition of 2,6-diethylaniline pure or mixed with 1,2,3,4-tetrahydroquinoline was studied at 623 K, 7 MPa in a flow reactor with dimethyldisulfide added to the feed. It is shown that 1,2,3,4-tetrahydroquinoline inhibits the decomposition of 2,6-diethylaniline, which inhibition depends on the concentration of the former.
