A thermosetting plastic foam solid formed from the reaction product of: (a) either polyisocyanate or isocyanate-based foam; (b) a polyol-based foam; (c) a catalyst which is capable of promoting the thermosetting reaction between the polyisocyanate or isocyanate-based foam and the polyol-based foam; and (d) a blowing agent which comprises a high purity cyclopentane product, wherein the high purity cyclopentane product is about 95% or greater pure cyclopentane, and, optionally, (e) water and/or (f) liquid flame retardant.

Thermosetting plastic foam

The present invention relates to a method for using a single distillation column to recover the reactants and products from the reaction of a cyclic diolefin and an olefin to produce an alkenyl bridged ring compound.

Production of alkenyl bridged ring compounds

A method for producing a cyclopentane product which comprises the following steps: (a) cracking dicyclopentadiene to form a cyclopentadiene-rich stream and a higher boiling liquids stream; (b) separating the cyclopentadiene-rich stream from the higher boiling liquids stream; (c) diluting the cyclopentadiene-rich stream with recycled saturates such that the cyclopentadiene content is limited to between about 5-50%; (d) conducting a first hydrogenation of the cyclopentadiene-rich stream in the presence of hydrogen and a first catalyst, and at a temperature (i.e., preferably between about 26 to 94.degree. C., more preferably in the range between about 37 to 66.degree. C.) which is capable of avoiding the repolymerization of cyclopentadiene to dicyclopentadiene, thereby forming a cyclopentadiene-depleted stream; (e) conducting a second hydrogenation of the cyclopentadiene-depleted stream in the presence of a second catalyst wherein any residual olefins and/or cyclopentadiene contained within the cyclopentadiene-depleted stream are saturated, thereby forming a crude cyclopentane product; and (f) flash stripping the crude cyclopentane product to form the cyclopentane product comprising about 95% pure cyclopentane.

Process for forming cyclopentane from dicyclopentadiene

A thermosetting plastic foam solid formed from the reaction product of: (a) either polyisocyanate or isocyanate; (b) a polyol; (c) a catalyst which is capable of promoting the thermosetting reaction between the polyisocyanate or isocyanate and the polyol; and (d) a blowing agent comprised at least partially from a high purity cyclopentane product, wherein the high purity cyclopentane product is about 95% or greater pure cyclopentane, and, optionally, (e) water and/or (f) liquid flame retardant.
