Condensation of cyanides with polyhydric phenols in the presence of hydrogen chloride and zinc chloride to yield phenolic ketones.
Industry:Chemistry
Aromatic (ring) compounds must have 4n _ 2 pibonding electrons, where n is a whole number and generally limited to n _ 0 to 5. When n _ 1, for example, there are six pi-electrons, as for benzene. Also known as Hu ckel’s rule.
Industry:Chemistry
Production of an alkyl halide by boiling a silver carboxylate with an equivalent weight of bromine in carbon tetrachloride.
Industry:Chemistry
C<sub>11</sub>H<sub>15</sub>O<sub>3</sub>N A colorless solid with a melting point of 91_C; used as an insecticide for cockroaches, flies, mosquitoes, and lawn insects.
Industry:Chemistry
(CH<sub>3</sub>)<sub>2</sub>CHC<sub>6</sub>H<sub>4</sub>NHCON(CH<sub>3</sub>)<sub>2</sub> A crystalline solid with a melting point of 151–153_C; solubility in water is 170 parts per million; used as an herbicide for wheat, barley, and rye.
Industry:Chemistry
A reagent that is similar to a Grignard reagent, and that is formed by reacting an arylacetic acid or its sodium salt with isopropyl magnesium halide.
Industry:Chemistry
C<sub>10</sub>H<sub>4</sub>NH<sub>2</sub>OH(SO<sub>3</sub>H)<sub>2</sub> An acid derived from naphthylamine trisulfonic acid; used in dye manufacture.
Industry:Chemistry
A molecular structure of a cyclic conjugated system that is depicted with alternating single and double bonds.
Industry:Chemistry
A method of synthesizing a higher aldose from a lower aldose; monosaccharides, such as aldehydes and ketones, react with hydrogen cyanide to form cyanohydrins, which are hydrolyzed to hydroxy acids, converted to lactones, and reduced to aldoses with sodium amalgams.
Industry:Chemistry
The condensation of aldehydes with compounds containing an activated methylene (_CH<sub>2</sub>) group.
