Abstract

1,255,524. Purifying isoprene. GOODYEAR TIRE & RUBBER CO. 8 Aug., 1969 [11 Sept., 1968], No. 39813/69. Heading C5E. The cyclopentadiene content of isoprene streams is lowered, e.g. to below 1 p.p.m., by fractional distillation in the presence of at least 3% of 2-pentene and at least 5% of 2-methyl-2- butene, there being a total of at least 10% of these two materials, all percentages being based by weight on the total weight of the stream.
