Toluidine
IUPAC 名称
(1Z)-1-[2-(4-methyl-2-nitrophenyl)hydrazin-1-ylidene]-1,2-dihydronaphthalen-2-one
描述
Toluidine, also known as toluidine red or c.i. pigment red 3, is a member of the class of compounds known as naphthalenes. Naphthalenes are compounds containing a naphthalene moiety, which consists of two fused benzene rings. Toluidine is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Toluidine can be found in wild celery, which makes toluidine a potential biomarker for the consumption of this food product. The chemical properties of the toluidines are quite similar to those of aniline, and toluidines have properties in common with other aromatic amines. Due to the amino group bonded to the aromatic ring, the toluidines are weakly basic. The toluidines are poorly soluble in pure water but dissolve well in acidic water due to formation of ammonium salts, as usual for organic amines. ortho- and meta-toluidines are viscous liquids, but para-toluidine is a flaky solid. This difference is related to the fact that the p-toluidine molecules are more symmetrical. p-Toluidine can be obtained from reduction of p-nitrotoluene. p-Toluidine reacts with formaldehyde to form Tröger's base .
