| titleOfInvention | Method for producing 2,6-dimethylnaphthalene |
| abstract | PROBLEM TO BE SOLVED: To selectively and efficiently produce 2,6-dimethylnaphthalene by methylating naphthalene or methylnaphthalene in the presence of a solid acid catalyst. SOLUTION: A naphthalene or 2-methylnaphthalene is used as a raw material, and a methylating agent comprising methanol or dimethyl ether is reacted in the presence of a zeolite catalyst having a major pore diameter in a range of 5.8 to 6.8A to obtain 2,2. When producing 6-dimethylnaphthalene, the reaction temperature is 300-4. In the range of 50 ° C., the corresponding reaction pressure is in the range of 0.2 to 6.5 times the critical pressure of the methylating agent, and the reaction is performed under the condition that the methylating agent is in a subcritical or supercritical state. When the density of the methylating agent in the reaction system is in the range of 0.02 to 0.25 g / ml, the selectivity of 2,6-dimethylnaphthalene is improved as shown in FIG. |
