Method for preparing 3-ethylbenzophenone |
| abstract |
ABSTRACT OF THE DISCLOSURE The present invention provides a method for preparing 3-ethylbenzophenone in a high purity which comprises the steps of alkylating benzene with ethylene in the presence of an alkylating catalyst to obtain an alkylated product composed mainly of unreacted benzene, ethylbenzene, poly-ethylbenzenes and heavier substances; subjecting the alkylated product to rectification in order to recover therefrom a fraction which has a temperature range of boiling points within the range of 275 to 310°C (in terms of atmospheric pressure); heating the recovered fraction together with a mixture of nitric acid and water; carrying out purification, if necessary; and performing distillation to recover therefrom 3-ethylbenzophenone represented by the formula (I): . . .
