Origin: A borrowing from French. Etymon: French paraffinique.

Etymology: < French paraffinique (in acide paraffinique paraffinic acid (P. Champion & H. Pellet 1872, in Bull. de la Soc. Chim. de Paris 18 247)) < paraffine paraffin n. + -ique -ic suffix.

1873 F. W. Clarke Constants of Nature i. 237 (table) Paraffinic acid. C₂₆H₂₆NO₁₀.

1890 Spectator 11 Sept. 462/1 Chemists are persuaded that the ethylenic form of linkage is not the equivalent of two paraffinic linkages.

1947 Jrnl. Royal Aeronaut. Soc. 51/1 The present fuel used is a kerosine which has a paraffinic base.

1968 New Scientist 31 Oct. 268/3 Classifying compounds into paraffinic, ethylenic and heteroaromatic heterocyclic compounds.

1975 Sci. Amer. June 92/3 Their chromatogram showed a large component of paraffinic waxes that have a high boiling point.

1983 F. J. McQuillin & M. S. Baird Alicyclic Chem. (ed. 2) i. 12 The bond interactions..are in fact reduced by expansion of the carbon-carbon bond angles to an average..above the normal paraffinic angle.

1999 Proc. National Acad. Sci. U.S.A. 96 3472/2 Paraffinic (waxy) components, which precipitate out at low temperatures, are removed.

Compounds

paraffinic acid n. (a) now rare, a nitrogen-containing acid obtained by heating paraffin with a mixture of nitric and sulphuric acids; (b) any of various carboxylic acids derived from paraffins.

ΚΠ

1873Paraffinic acid [see main sense].

1906 H. F. Morley & M. M. P. Muir Watts' Dict. Chem. III. 802/1 Champion..has shown that nitrosulphuric acid slowly transforms it [sc. paraffin] at 90° into a liquid oil of the composition C₁₃H₂₆NO₅ (called paraffinic acid)... Fuming nitric acid, according to Pouchet, also acts upon paraffin at 110°, forming a true paraffinic acid C₂₄H₄₈O₂..together with other fatty acids.

1936 S. A. Waksman Humus vi. 137 Paraffinic acid, C₂₄H₄₈O₂, was isolated..from the cold alcoholic extract.

1985 Analyt. Chem. 57 2207/1 Early work concentrated on identification of individual low molecular weight paraffinic acids for purposes of commercial scale isolation and purification.

† paraffinic nitrite n. Obsolete rare an organic compound consisting of an alkane in which a hydrogen atom has been substituted by a nitrito group —ONO.
