ABSTRACT:
A water-white, essentially odorless liquid useful as a dieletric oil and as a dye solvent, particularly for a carbonless paper solvent, consisting essentially of about 82% to about 88% by weight of mono-sec-butylbiphenyl and about 12% to about 18% of di-sec-butylbiphenyl prepared by reacting highly pure 1-butene or 2-butene with biphenyl at a mol ratio of butene to biphenyl of from about 0.5 to about 0.9 and at a temperature of about 250.degree. F. to about 475.degree. F. in the presence of an aluminum chloride catalyst, distilling the reaction product under vacuum to remove unreacted biphenyl and distilling off the product mixture at a temperature between about 370.degree. F. and about 440.degree. F. at 30 mm Hg. pressure or the equivalent thereof.
