| titleOfInvention | Production of 1-alkyl-7-methylnaphthalenes |
| abstract | PURPOSE: To obtain the subject substances by methylating a 1-lower alkylnaphthalene using a layer compound in which activated clay or exchangeable cations are exchanged with protons, ions such as Al or polynuclear hydroxide ions such as Al or Zr as a catalyst. n CONSTITUTION: A 1-lower alkylnaphthalene (e.g. 1-methylnaphthalene or 1- ethylnaphthalene) is reacted with a methylating agent composed of hexamethylbenzene or pentamethylbenzene using activated clay or an ion exchange type layer compound as a catalyst to produce the subject substances. A layer compound (e.g. montmorillonite or saponite) exchanged with protons, ions such as Al, Fe, Ga or Ti or polynuclear hydroxide ions such as Al, Zr, Fe or Cr is used as the ion exchange type layer compound. The amount of the catalyst used is 0.01-60 pts. wt. based on 100 pts.wt. raw material and the reaction temperature is 80-280°C. n COPYRIGHT: (C)1992,JPO&Japio |
