摘要： Polyacetylene compounds and process for the preparation thereof from a chiral dihydroxy amide are described. The compounds preferably have diacyl groups attached to the amide. The compounds are useful for making films which are electrically conductive, near infrared absorbing, polarizing, and have the optical characteristic and other properties of polyacetylenes.

摘要： A process for the rejection of heavy reaction by-products from a selective hydrogenation reaction zone effluent containing butadiene and trace amounts of heavy reaction by-products by introducing the selective hydrogenation reaction zone effluent into a butadiene extraction vaporizer containing a fractionation zone, refluxing the fractionation zone with a raffinate stream from a butadiene extraction zone; removing a vaporized stream containing butadiene and having a reduced concentration of heavy reaction by-products from the vaporizer; removing and recovering a concentrated liquid product stream containing heavy reaction by-products from the vaporizer; and introducing the vaporized stream containing butadiene into the butadiene extraction zone.
