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 with the aid of an alkylating catalyst to obtain an alkylated product composed mainly of unreacted benzene, ethylbenzene, polyethylbenzenes and heavier by-products; subjecting the alkylated product to distillation 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); dehydro-genating the recovered fraction at a reaction temperature within the range of 200 to 700°C in the presence of a dehydrogenating catalyst; oxidizing the dehydrogenated fraction in a liquid phase; and performing distillation to recover therefrom 3-ethylbenzophenone represented by the formula: ...
