What happens when P toluidine reacts with HCL?
The hydrochloric acid will convertp-toluidine into its hydrochloride salt which on extraction will moFVe into aqueous layer. Freep-toluidine can be recovered by hydrolping this salt with an aqueous base. The neutral compound, naphthalene, will stay in etheral layer and can be recovered by evaporation of the solution.
Is P toluidine an acid or base?
basic
Due to the amino group bonded to the aromatic ring, the toluidines are weakly basic.
Where does toluidine come from?
o-Toluidine is produced industrially by nitration of toluene to give mixture of nitrotoluenes, favoring the ortho isomer. This mixture is separated by distillation.
Is O-toluidine soluble in water?
Aminotoluenes are organic aromatic compounds containing a benzene that carries a single methyl group and one amino group. O-toluidine is soluble (in water) and a strong basic compound (based on its pKa).
Is P-toluidine carcinogenic?
The National Institute of Occupational Safety and Health (NIOSH, 2010) identifies p-toluidine as a potential carcinogen and recommends that occupational exposures to carcinogens be limited to the lowest feasible concentration.
What is the melting point of p-toluidine?

What is difference between toluene and toluidine?
is that toluene is (organic compound) a colourless, inflammable liquid hydrocarbon, methylbenzene, ch3c6h5, used as a solvent, in high-octane fuels and in the production of many chemical compounds while toluidine is (organic compound) any of the three isomeric aromatic amines derived from toluene; they are used in the …
Is P-toluidine nonpolar?
It’s polar because of the carboxyl group, but it’s not as polar as say formic acid or acetic acid because of the size of the benzene framework.
What is toluidine used for?
o-Toluidine (CAS no. 95-53-4) is a synthetic chemical that is a light yellow liquid at ambient temper- ature. It is used primarily in the manufacture of dye- stuffs, although it is also used in the production of rubber, chemicals, and pesticides and as a curing agent for epoxy resin systems.
What color is O-Toluidine?
colorless
O-toluidine appears as a clear colorless or light yellow liquid. May become reddish brown on exposure to air and light. Flash point 185°F. Has about the same density as water and is very slightly soluble in water.
What is O-toluidine used for?
ortho-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 …
