  • Solvent extraction
    Patent number: 4045332
    Abstract: The degradation of furfural, used in the solvent extraction of aromatics, is inhibited by the use of a furfural-soluble, recoverable amine having a pK.sub.a greater than that of aniline. The preferred amine is N,N-diethyl aniline and the amount used may be 0.001 to 5% wt., preferably 0.01 to 2% wt. by weight of furfural.The recoverable amine may be used in combination with a non-recoverable amine, eg. tri-ethanolamine, the amount of non-recoverable amine being preferably 1 to 1000 ppm wt., particularly 5 to 50 ppm.
