| titleOfInvention | Preparation of 2,2-diethyltoluene |
| abstract | A diethyltoluene mixture rich in 2,5-diethyltoluene and containing less tha 5% of the 3,5-diethyltoluene can be prepared by methylating 1,4-diethylbenzene with an excess of methanol in the presence of amorphous silica-alumina catalysts. The most desirable catalysts have a silica:alumina ratio from about 2:1 through about 9:1. Methylation is conveniently effected in a temperature range between about 300 DEG C. and about 450 DEG C. and most desirably in a hydrogen atmosphere. |
