Kind Code:
B1
Abstract:
Method by which an esterification precursor is continuously converted to an esterification reaction product liquid by admixing a feed stream of the precursor into and with a circulating stream of the product liquid, heating the admixture to vaporize a low-boiling component, the heating being at a sufficient temperature and for a sufficient time to convert the precursor to the product liquid, maintaining circulation of the admixture by separating the low-boiling component therefrom, thereby establishing a flow of liquid from a more dense zone to a less dense zone in the circulating liquid stream, and continuously withdrawing a stream of the product liquid from the circulating admixture. The method further includes converting the precursor to a protopolymeric liquid having substantially uniformly suspended therein particulate solid matter.
