| titleOfInvention | A kind of synthesis technique of ethylene glycol mono-tert-butyl ether |
| abstract | The invention relates to the field of chemistry and chemical industry, and particularly discloses a synthesis process of ethylene glycol mono-tert-butyl ether. The synthesis process of the ethylene glycol mono-tert-butyl ether is characterized by: (1) adding a certain amount of raw materials into four raw material tanks of EG, mixed C 4 , ETB and DBE respectively; each raw material tank is kept constant by nitrogen. (2) Fill the sulfonated activated carbon into the fixed bed reaction tube, and fully purge the fixed bed system with nitrogen; (3) Stop nitrogen purging, turn on the EG metering pump to pressurize the system to the set pressure, and turn on preheating The reactor is heated to the set temperature, and at the same time, the heating medium in the jacket of the fixed-bed reaction tube starts to circulate at the set temperature. By precisely controlling the ratio of ethylene glycol di-tert-butyl ether in the raw material, the production of ethylene glycol di-tert-butyl ether is suppressed, thereby improving the selectivity of ethylene glycol mono-tert-butyl ether. In addition, the invention adopts the sulfonated activated carbon as the catalyst, the raw material is cheap and easy to obtain, the catalyst activity and stability are high, and the economy is good. |
