| titleOfInvention | Method for catalyzing toluene selective chlorination by using H-L type molecular sieve |
| abstract | The invention discloses a method for catalyzing toluene selective chlorination by using an H-L type molecular sieve. The method is used for carrying out orientated chlorination on toluene by adopting the H-L type molecular sieve as a main catalyst, chloroacetic acid as a cocatalyst and Cl2 as a chlorinating agent through a liquid-phase chlorinating method. According to the H-L type molecular sieve, the ratio of SiO2/Al2O3 is 16-31 and crystallization time is 48 hours-120 hours, and the H-L type molecular sieve is prepared through a hydro-thermal method and an ion exchange method. The invention also provides a preparation method of the H-L type molecular sieve. The toluene selective chlorination method is simple in process and mild in reaction conditions; and the used L type molecular sieve is good in catalytic activity and stability, can be easily separated from products, and can be used for remarkably improving toluene conversation rate and parachlorotoluene selectivity, and therefore, the method has very high industrial application value. |
