FESTE PHOSPHORSAEURE-KATALYSIERTE ALKYLIERUNG VON AROMATISCHEN KOHLENWASSERSTOFFEN.

摘要

SOLID PHOSPHORIC ACID CATALYZED ALKYLATION OF AROMATIC HYDROCARBONS A process for the alkylation of aromatic hydrocarbons using a solid phosphoric acid catalyst in which liquid phosphoric acid is removed from the bottoms stream of the rectification column to which the alkylation zone effluent is charged. The acid is removed by passing the bottoms stream into a settling vessel operated at a lower pressure and temperature than the bottom of the rectification column.
