Abstract

PURPOSE: To remove acidic substances from a hydrocarbon washing liquid separated from a polyolefin prepared by the use of a Ziegler-Natta catalyst, easily and in high efficiency, by treating the liquid with a tert-alcohol.
CONSTITUTION: A hydrocarbon washing liquid discharged from the de-ashing process of polyolefin prepared by the use of a halogen-containing metal catalyst such as titanium trichloride, etc., represented by Ziegler-Natta catalyst, is treated with a tert-alcohol (pref. 4W8C tert-alcohol, e.g. 2-methyl-2-propanol, etc.) to remove the acidic substances from the washing liquid.
EFFECT: Easy recovery and purification of the liquid. Non-corrosive to the process equipment.
