Abstract:
A process for preparing an arylpropene from a diarylpropane by gas phase thermolysis in the presence of solid porous catalyst comprising silica having large pore volume and low acidity.

Claim (Index 16):
A process for preparing a compound of formula (I) comprising contacting a compound of formula (II) in the gas phase with a solid porous catalyst comprising silica, wherein k is, independently from each other, 0, 1, 2 or 3; R 1  is, independently from each other, hydroxy, C 1 -C 6  alkoxy, di(C 1 -C 6 -alkyl) aminyl; wherein the catalyst has a pore volume of at least 0.5 cm 3 /g as determined by Hg porosimetry according to DIN 66133, and an acidity characterized by an amount of adsorbed ammonia of at most 0.1 mmol/g(catalyst) as determined by NH 3 -TPD.
