Group of organic azo pigments with strong tinting power, but poor opacity in paints; used where nontoxicity is important.
Industry:Chemistry
The reaction whereby a pyrrole compound is formed when a _-ketoester, chloroacetone, and a primary amine condense.
Industry:Chemistry
Preparation of an ester or _-halo substituted acid (chloro or bromo) by reacting the halogen on the acid in the presence of phosphorus or phosphorus halide, and then followed by hydrolysis or alcoholysis of the haloacyl halide resulting.
Industry:Chemistry
Production of substituted phenylacetic acids by the oxidation of the corresponding alkylbenzene by potassium permanganate in the presence of acetic acid.
Industry:Chemistry
A technique to separate a mixture of primary, secondary, and tertiary amines; they are heated with ethyl oxalate; there is no reaction with tertiary amines, primary amines form a diamide, and the secondary amines form a monoamide; when the reaction mixture is distilled, the mixture is separated into components.
Industry:Chemistry
The action of bromine and an alkali on an amide so that it is converted into a primary amine with one less carbon atom.
Industry:Chemistry
The thermal decomposition of quaternary ammonium hydroxide compounds to yield an olefin and water; an exception is tetramethylammonium hydroxide, which decomposes to give an alcohol.
Industry:Chemistry
Preparation of alkylisothiocyanates by heating together a primary amine, mercuric chloride, and carbon disulfide.
Industry:Chemistry
A reaction in which amides are degraded by treatment with bromine and alkali (caustic soda) to amines containing one less carbon; used commercially in the production of nylon.
Industry:Chemistry
A chemical rearrangement of the hydrohalides of N-alkylanilines upon heating to give aminoalkyl benzenes.
