Bromoethylation of aromatic hydrocarbons |
| abstract |
An aromatic hydrocarbon is bromoethylated to a 1-bromo-1-arylethane with minimal co-formation of diarylalkane by-product by reacting it with hydrogen bromide and acetaldehyde at a temperature in the range of +10 DEG C to -35 DEG C in the presence of at least about one mol of hydrogen sulfate per mol of the aromatic hydrocarbon and in the absence of more than bout 15% by weight of water, based on the weight of the hydrogen sulfate. The process is of particular advantage in the bromoethylation of the less reactive aromatic hydrocarbons, such as isobutylbenzene and other monoalkylaromatic hydrocarbons, which have previously yielded an undesirable amount of diarylalkane when bromoethylated with acetaldehyde and hydrogen bromide. |
