Zur Frage des Trocknens fetter Öle

A Summary of the Reactions of Aldehydes with Amines.

“…Further complications are noted if aniline hydrochloride and acetaldehyde are allowed to stand in water solution for several weeks. Under these circumstances at least two more amorphous products are formed, both of which correspond empirically to higher polymers of ethylideneaniline (40,130). These polymers (generally designated as "Schultze's base") are probably derived from Eckstein's base, since the latter can be converted to Schultze's base by treatment with dilute hydrochloric acid at room temperature.…”

“…These polymers (generally designated as "Schultze's base") are probably derived from Eckstein's base, since the latter can be converted to Schultze's base by treatment with dilute hydrochloric acid at room temperature. Eckstein's base also reacts with benzaldehyde when heated, but the product thus obtained is a definitely crystalline material, and probably has the structure of a benzalquinaldine-namely, -styrylquinoline (40).…”
