METHOD OF REMOVING ALUMINIUM-CONTAINING CATALYST FROM PHENOL ALKYLATION PRODUCTS

Method of removing aluminium-containing catalyst from phenol alkylation products comprises treating phenol alkylation products with water at a temperature of 165-250.degree.C, with water being in molar excess to aluminium in a range of 3-20. The resulting residue of meta-aluminate is easily separate...

Beschreibung
Zusammenfassung:	Method of removing aluminium-containing catalyst from phenol alkylation products comprises treating phenol alkylation products with water at a temperature of 165-250.degree.C, with water being in molar excess to aluminium in a range of 3-20. The resulting residue of meta-aluminate is easily separated by filtration. The present invention allows eliminating constant control of aluminium content in alkylation products, easily removing the catalyst therefrom and eliminating the loss of phenol alkylation products.
