摘要:
A continuous process comprising: a) separating a starting epoxy novolac resin comprising oligomers having an average functionality of greater than 2.5 and a hydrolyzable chlorine content of less than 450 ppm with a first continuous evaporator apparatus under a vaporization temperature in the range of from 150° C. to 250° C. and an absolute pressure of from 0.05 to 1 mmHg absolute to form a first vapor fraction comprising epoxy novolac resin having more than 95 weight percent of 2-functional components and wherein the mass of the first vapor fraction is in the range of from 5 to 20 weight percent of the starting epoxy novolac resin; and a first bottom fraction comprising epoxy novolac resin having a lower weight percent of 2-functional components in comparison with the weight percent of 2-functional components of the starting epoxy novolac resin; b) recovering the first bottom fraction; and c) condensing from 95 weight percent to 99.95 weight percent of the first vapor fraction at a temperature in the range of from 50° C. to 200° C. to form a first partially condensed vapor fraction product having at least 95 weight percent of 2-functional components and having a total chlorine content of less than 900 ppm and an uncondensed vapor product comprising halogenated impurities, is disclosed.
