Abstract

PURPOSE: To obtain the titled substance rich in m- and p- substitution products, simply without problems of corrosion of apparatuses and pollution, by reacting biphenyl with a lower olefin in the presence of a catalyst, e.g. silica -alumina or zeolite, under given conditions.
CONSTITUTION: One mole biphenyl is reacted with 0.5W5mol lower olefin in the presence of a catalyst, e.g. silica-alumina or zeolite, at 180°C or above, to give an alkylbiphenyl rich in the m- and p- substitution products. The silica-alumina catalyst has an alumina content of 10W30wt%, and the zeolite catalyst is any of the natural or synthetic ones and may be used alone or in a mixture. The particle diameter of the catalyst is most preferably 20W150μ, and the catalyst is activated by calcining in the air at 400W850°C. The amount of the catalyst is 0.5W10wt%, preferably 1W5wt%, based on the biphenyl.
USE: An electrical insulating oil, a solvent for pressure-sensitive paper and a heating medium oil.
