Toluidine is used as an intermediate in the synthesis of the large-volume herbicides, metolachlor and acetochlor, in the manufacture of more than 90 dyes and pigments (e.g. acid-fast dyestuffs, azo pigment dyes, triarylmethane dyes, sulfur dyes, and indigo compounds), and as an intermediate for synthetic rubber .Very slightly soluble in water. P-TOLUIDINE neutralizes acids to form salts plus water in exothermic reactions.
p-Toluidine is used as an intermediate in themanufacture of various dyes. It is also usedas a reagent for lignin and nitrites.
Other Names
p-TOLUIDINE HYDROCHLORIDE FOR SYNTHESIS
Procedure
Very slightly soluble in water. P-TOLUIDINE neutralizes acids to form salts plus water in exothermic reactions.
Note
In p-toluidine, the presence of electron-donating −CH3 group increases the electron density on the N-atom. Thus, p-toluidine is more basic than aniline. −NO2 group decreases the electron density over the N−atom in p-nitroaniline.
