Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: methyl n., aniline n.

Etymology: < methyl n. + aniline n., after German Methylanilin (A. W. Hofmann 1850, in Ann. der Chem. u. Pharm. 74 150).

Chemistry.

An aniline derivative, C₆H₅NHCH₃, that is methylated on the nitrogen atom and that is a basic, colourless liquid that turns brown on exposure to air.

ΚΠ

1850 Philos. Trans. (Royal Soc.) 140 113 The deportment of aniline with bromide of methyl resembles its behaviour with the ethyl-compound. The mixture rapidly solidifies into a crystalline mass of hydrobromate of methylaniline.

1866 Philos. Trans. (Royal Soc.) 156 65 The addition of CH₂ to aniline converts the latter into methyl-aniline.

1906 H. F. Morley & M. M. P. Muir Watts' Dict. Chem. III. 284/2 On pouring the product into water the acetyl derivative of methyl-aniline separates in long needles.

1921 Science 8 July 36/1 Secondary bases, typified by methylaniline, do not react at all with urea.

1964 N. G. Clark Mod. Org. Chem. xxii. 448 Alkylation on the nitrogen produces a slightly stronger base, as evidenced by an increased basicity along the series: aniline, N-methylaniline, NN-dimethylaniline.

1994 Proc. National Acad. Sci. U.S.A. 91 8882/1 These compounds therefore have the same 6-s conformation in the solid state as the perchlorate salt of the pSB [= protonated Schiff base] of all-trans-retinal with N-methylaniline.
