This application relates to the field of organic synthetic chemistry, specifically disclosing a method for synthesizing o-chlorobenzylamine. The method uses o-chlorobenzyl, liquid ammonia, and liquid alkali as raw materials. The preparation process mainly includes amination reaction, liquid ammonia recovery, alkali treatment for deamination, and product purification steps. Specifically, in a high-pressure reactor, liquid ammonia is used as the reaction medium, reacting with o-chlorobenzyl under low temperature and specific pressure conditions. After the reaction, the liquid ammonia is distilled off and recovered for recycling. Then, the ammonia is dissolved in water, released with alkali, and residual ammonia is removed under negative pressure. Finally, the organic phase is separated by static layering, followed by dehydration and filtration to obtain a high-purity o-chlorobenzylamine product. This method significantly suppresses side reactions by constructing a solvent-free system and synergistically controlling the reaction temperature, material ratio, and post-treatment parameters, thereby achieving highly selective synthesis. The entire process has the advantages of simple operation, environmental friendliness, high resource utilization, and ease of industrial implementation.
