This invention belongs to the field of organic synthesis technology and discloses a method for preparing trans-3-chloro-2-propenylhydroxylamine hydrochloride. The method involves adding trans-1,3-dichloropropene to a ketoxime, a base, a phase transfer catalyst, and a first solvent for etherification. After the reaction, the mixture is first extracted with an extractant, and the resulting oil phase is then distilled to obtain the oxime ether. The oxime ether, an aqueous hydrochloric acid solution, and a second solvent are mixed and subjected to vacuum distillation in a distillation column to obtain trans-3-chloro-2-propenylhydroxylamine hydrochloride. This invention avoids the use of an aqueous base in the etherification stage, effectively preventing the hydrolysis of the ketoxime. The purified oxime ether obtained in the etherification step is purified by distillation, significantly reducing side reactions during the subsequent hydrolysis. Adding a solvent during the hydrolysis stage allows for better mixing of the aqueous hydrochloric acid solution and the oxime ether, resulting in more uniform acidification, a more complete reaction, and improved conversion and selectivity.
