Inert organic solvent dispersion of alkali hydroxide and reaction using the same |
摘要 |
An inert organic solvent dispersion of alkali hydroxide is prepared by mixing an alkali hydroxide, an inert organic solvent and a stabilizer and heating and stirring at the temperature for forming the pasty alkali hydroxide and cooling the dispersion. The dispersion of alkali hydroxide is used in a reaction of an active methylene compound with an organoalkyl halide such as a reaction of a halophenylacetonitrile with an isopropyl halide to obtain alpha -isopropyl halophenylacetonitrile.
