picolinen.

Brit.

/ˈpɪkəliːn/, U.S.

/ˈpɪkəˌlin/,

/ˈpɪkəˌlaɪn/

Forms: 1800s– picolin, 1800s– picoline.

Origin: A borrowing from Latin, combined with English elements. Etymons: Latin pic- , pix , -ol suffix, -ine suffix⁵.

Etymology: < classical Latin pic-, pix pitch n.¹ + -ol suffix + -ine suffix⁵ (see quot. 1846). Compare German Picolin (T. Anderson 1846, in Ann. der Chem. u. Pharm. 60 89). Compare also French picoline (1850). N.E.D. (1906) gives the pronunciation as (pi·kŏləin) /ˈpɪkəlaɪn/.

Chemistry.

Each of three colourless, pungent-smelling, liquid bases, (CH₃)C₅H₄N, that are isomeric methyl derivatives of pyridine and are obtained from coal tar, bone oil, etc.; spec. the α-isomer (2-methylpyridine).
