| titleOfInvention | A kind of synthetic method of hydroxybenzylamine |
| abstract | A method for synthesizing hydroxybenzylamine belongs to the technical field of organic synthesis. The principle of the method is: demethylation reaction of methoxybenzylamine under the action of hydrobromic acid. The characteristics of the invention are: methoxybenzylamine and hydrobromic acid are in a reflux state, and excess water is distilled off to remove excess water. Increase the reaction temperature, increase the concentration of hydrobromic acid in the reaction mixture, thereby enhancing the demethylation of hydrobromic acid to methoxybenzylamine, thereby shortening the reaction time and improving the conversion rate; when no more methyl bromide gas is observed to produce Continue to distill after, reclaim excessive hydrobromic acid to further improve reaction temperature, improve conversion rate, reduce the consumption of raw material hydrobromic acid simultaneously, can reduce the processing capacity of subsequent steps and the consumption of raw material sodium hydroxide again, therefore the present invention It has the advantages of simple process, short reaction time, easy purification of products, low consumption of raw materials and high reaction yield. |
