This invention discloses a method for extracting the intermediate ACH, belonging to the field of fine chemicals. The method involves passing a layered acid containing acesulfame potassium (DCM) and a dichloromethane solution into a rotary extraction tower for extraction. The temperature of the layered acid entering the tower is 30-31°C. The extraction pressure and the temperature of the dichloromethane entering the tower are controlled. The extracted dichloromethane layer enters a vibrating extraction tower for back-extraction with deionized water. The back-extracted DCM is neutralized, concentrated, crystallized, and dried to obtain the finished product, potassium acesulfame potassium. Using this method, the ACH content in the extracted acid is reduced to below 0.1%, and the ACH extraction yield reaches over 98%. Because the rotary extraction tower effectively reduces the acid carryover in the DCM, it lowers the back-extraction load, ensuring the product quality of potassium acesulfame potassium. Simultaneously, it simplifies the process conditions, reduces energy consumption, and saves production costs.
