Purifying detergent alkylates

Detergent alkylate is purified to remove suspended sludge derivd from aluminium halide alkylation catalysts, e.g. AlCl3 or AlBr3 used during the prepn. by treating with anhydrous ammonia to coagulate and ppte. the sludge. Pref. the amount of sludge present is 0.1-0.7 wt. %., and 0.01-0.2 wt. % ammon...

Zusammenfassung:Detergent alkylate is purified to remove suspended sludge derivd from aluminium halide alkylation catalysts, e.g. AlCl3 or AlBr3 used during the prepn. by treating with anhydrous ammonia to coagulate and ppte. the sludge. Pref. the amount of sludge present is 0.1-0.7 wt. %., and 0.01-0.2 wt. % ammonia is used in the treatment. Treatment temp. is e.g. 25-60 degrees C.
