/ˈmɔːfəlɪn/, U.S.

/ˈmɔrfəˌlin/,

/ˈmɔrfəl(ə)n/

Origin: A borrowing from German. Etymon: German Morpholin.

Etymology: < German Morpholin (L. Knorr 1889, in Berichte der Deutsch. Chem. Ges. 22 2083) < Morphin morphine n., with insertion of -ol- (compare -ol suffix).

Chemistry.

A cyclic amine, C₄H₉NO, which is a hygroscopic oil used as a solvent for resins and dyes and whose fatty-acid salts are emulsifying soaps used in floor polishes.
