Application 07/861,332
is combined with a body of heat transfer fluid maintained within
a reaction vessel at a temperature effective to convert
dicyclopentadiene to cyclopentadiene monomer vapor, the
improvement which comprises:
(i) agitating said body of heat transfer fluid
maintained in said reaction vessel;
(ii) introducing monomer and heat transfer fluid free
molten dicyclopentadiene into said agitated body of heat transfer
fluid,
wherein said introduction is made sufficiently below
the surface of said heat transfer fluid to provide substantially
complete conversion of said introduced dicyclopentadiene to
cyclopentadiene monomer vapor, and
wherein said agitation of said body of heat transfer
fluid facilitates said substantially complete conversion and the
escape of said monomer vapor from the surface of said agitated
body of heat transfer fluid;
(iii) rapidly removing said monomeric cyclopentadiene
vapor from the surface of said agitated body of heat transfer
fluid; and
(iv) directly condensing said removed monomeric
cyclopentadiene vapor to provide liquid cyclopentadiene monomer
wherein 98% to 100% of said molten dicyclopentadiene
introduced into said agitated body of heat transfer fluid in step
(ii) is converted into liquid cyclopentadiene monomer of 97% to
100% purity in step (iv), and
wherein negligible formation of high cyclopentadiene
polymers occur in said reaction vessel.
13. A system for converting 98% to 100% of a molten
dicyclopentadiene feed to liquid cyclopentadiene monomer of 97%
to 100% purity, which comprises:
(i) a reaction vessel to contain a body of heat
