Abstract
Process for changing the volatile aluminum chloride complex contained in an ethylbenzene production stream into a non-volatile, aluminum chloride product of a nature such that the ethylbenzene in the stream can be separated from the aluminum chloride catalyst by flash distillation. Conversion of the volatile aluminum chloride complex to a non-volatile aluminum chloride product is accomplished by adding selected alcohols, aldehydes, or ketones to the ethylbenzene stream.
