To*lu"ic (?), a. (Chem.) Pertaining to, or designating, one of three
metameric acids, CH3.C6H4.CO2H, which are related to toluene and
analogous to benzoic acids. They are white crystalline substances, and
are called respectively orthotoluic acid, metatoluic acid, and
paratoluic acid.
Tol"u*id (?), n. (Chem.) A complex double tolyl and toluidine
derivative of glycocoll, obtained as a white crystalline substance.
To*lu"i*dine (?), n. (Chem.) Any one of three metameric amido
derivatives of toluene analogous to aniline, and called respectively
orthtoluidine, metatoluidine, and paratoluidine; especially, the
commonest one, or paratoluidine, which is obtained as a white
crystalline substance.
It is used in the aniline dye industry, and constitutes the essential
nucleus or radical of those dyes.
{ Tol"u*ol, Tol"u*ole} (?), n. [Tolu + benzol.] (Chem.) Same as
Toluene.
To*lu"ric (?), a. [Toluic + uric.] (Chem.) Of, pertaining to, or
designating, any one of three isomeric crystalline acids, C9H10ON.CO2H,
which are toluyl derivatives of glycocoll.
Tol`u*ta"tion (?), n. [L. tolutim on a trot, properly, lifting up the
feet, akin to tollere to lift up.] A pacing or ambling. [Obs.] Sir T.
Browne.
Tol"u*yl (?), n. [Toluic + - yl.] (Chem.) Any one of the three
hypothetical radicals corresponding to the three toluic acids.
Tol"u*yl*ene (?), n. (Chem.) (a) Same as Stilbene. (b) Sometimes, but
less properly, tolylene.
Tol"yl (?), n. [Toluic + -yl.] (Chem.) The hydrocarbon radical,
CH3.C6H4, regarded as characteristic of certain compounds of the
aromatic series related to toluene; as, tolyl carbinol.
Tol"yl*ene (?), n. (Chem.) A hydrocarbon radical, C6H4.(CH2)2, regarded
as characteristic of certain toluene derivatives.
Tol`y*peu"tine (?), n. (Zoöl.) The apar.
