† paracyanicadj.

Origin: Formed within English, by derivation; modelled on a German lexical item. Etymons: para- prefix¹, cyanic adj.

Etymology: < para- prefix¹ + cyanic adj., after German Paracyansäure paracyanic acid (J. J. Johnstone 1837, in Ann. der Pharm. 22 281).

Chemistry. Obsolete.

Derived from cyanogen; † paracyanic acid n. Obsolete any of various acids supposed to be polymers of or isomeric with fulminic acid.

ΚΠ

1845 M. Faraday in Philos. Trans. (Royal Soc.) 135 169 When the cyanogen is made from cyanide of mercury.., the cyanogen distils back and condenses in the paracyanic residue of the distillation.

1854 J. W. Draper Kane's Elements Chem. (Amer. ed.) 514 The solution gives, with water, a yellow precipitate, which combines with bases, and has been termed Paracyanic Acid.

1877 H. Watts Dict. Chem. IV. 341 Paracyanic acid. This name is applied to several brown products..resulting from the decomposition of cyanogen or some of its compounds, in presence of water.
