| titleOfInvention | Method for preparing N-methyl-p-anisidine |
| abstract | The present invention relates to a chemical process method, in particular to a liquid-phase catalytic method for producing alkylated p-anisidine in the presence of hydrogen, which is used as a chemical or additive for gasoline to increase its octane number. The technical result of the claimed group of inventions is an increase in the yield of N-methyl-p-anisidine and a decrease in the yield of the dimethyl derivative. A method for preparing N-methyl-p-anisidine in a liquid phase, comprising respectively alkylating p-anisidine and formalin, respectively and simultaneously feeding into a catalyst directly positioned upstream of the catalytic reduction zone. In the mixer in the reactor, thereby forming the intermediate methaneimine, then at a temperature of 20-120 ° C, in a high-pressure hydrogen environment, reducing on a hydrogenation catalyst, and then separating the target product N-methyl-p-fennel amine. |
