| titleOfInvention | Process for the preparation of vinyl-substituted pyridine and quinoline compounds |
| abstract | Vinyl-substituted pyridine and quinoline compounds are obtained by dehydrating corresponding pyridine and quinoline alcohols by introducing the alcohol with water into triethanolamine, glycerol or a polyglycol containing 0.1 to 5% by weight of a caustic alkali or acid-reacting compound, while heating to 180 DEG to 200 DEG C. to distil off the vinyl compound and water vapour. A solution of the alcohol in water may be poured into the solvent, injected below the surface of the solvent or sprayed on to the surface of the solvent, or the alcohol may be introduced simultaneously with steam into the solvent. In examples 2-vinylpyridine is obtained from 2-pyridine-ethanol, 4-vinylpyridine is obtained from 4-pyridine-ethanol, 2-methyl-6-vinylpyridine is obtained from 2-methyl-6-pyridine-ethanol, and 2-vinyl-quinoline is obtained from 2-quinoline-ethanol; the solvents used are triethanolamine containing sodium hydroxide, glycerol containing potassium bisulphate, glycerol containing monoammonium phosphate and phosphoric acid, and a polyglycol containing sulphuric acid. |
