Abstract:
A method for producing alkenyl bridged ring compounds comprising:subjecting a feed comprising a mono-olefin and a cyclic diolefin to first conditions effective to produce a mixture comprising an alkenyl bridged ring product;subjecting said mixture to second conditions effective to separate said mixture into a light fraction and a heavy fraction wherein said heavy fraction comprises a major portion of said alkenyl bridged ring product;feeding said heavy fraction to a distillation column at a feed point;removing said alkenyl bridged ring product from said distillation column at a location above said feed point;heating a bottom portion of said distillation column under third conditions effective to decompose a part of heavy byproducts to form a recovered fraction comprising at least one compound selected from the group consisting of said mono-olefin, said cyclic diolefin, said alkenyl bridged ring product, and mixtures thereof; andseparating said recovered fraction from said heavy byproducts.
