† paramiden.

Forms: 1800s paramid, 1800s paramide.

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

Etymology: < para- prefix¹ + amide n., after German Paramid (F. Wöhler 1841, in Ann. der Chem. u. Pharm. 37 269).

Chemistry. Obsolete.

= mellitimide n.

1848 Chem. Gaz. 15 Aug. 324 The amount of euchronic acid can be very considerably increased and that of paramide diminished.

1852 W. Gregory Handbk. Org. Chem. (ed. 3) 61 When this salt [sc. ammonium mellitate]..is heated to 320°, it gives off ammonia and water, and there remains a mixture of two new compounds; a soluble one which contains euchronic acid,..and an insoluble one which is called paramide. Paramide is a yellow solid, like clay.

1892 H. F. Morley & M. M. P. Muir Watts' Dict. Chem. (rev. ed.) III. 201/1 An ammoniacal solution of paramide dropped into HClAq gives a white crystalline pp. called ‘paramic acid’ C₁₂H₅N₃O₇ (?).

1898 Jrnl. Amer. Chem. Soc. 20 665 The conversion of paramid into euchronamic acid would indicate that Wöhler's euchronic acid is an ortho compound.
