Abstract

The condensation between the aromatic and carbonyl compounds is effected over a silica gel and alumina catalyst, amorphous to X-rays, with SiO2/Al2O3 molar ratio from 50/1 to 300/1, with surface area from 500 to 1000 m2/g, with total pore volume from 0.3 to 0.6 ml/g, with mean pore diameter of the order of 10 A, and devoid or substantially devoid of pores with diameter greater than 30 A.
