ABSTRACT:
An aldehyde or ketone is condensed with an aromatic compound by contacting the aldehyde or ketone and the aromatic compound with a non-zeolitic molecular sieve, which has in its calcined form an adsorption of isobutane of at least about 2 percent by weight of the non-zeolitic molecular sieve at a partial pressure of 500 torr and a temperature of 20.degree. C. Among the condensations which can be effected is the condensation of acetone with phenol to produce bisphenol A.
