    摘要： A process is provided for preparing a low odor composition containing a dicyclopentenyl ester including the steps of preparing a distillation mixture containing the dicyclopentenyl ester and from 10 to 10,000 parts per million by weight based on weight of the dicyclopentenyl ester, of a suitable inhibitor; distilling the distillation mixture at a temperature in the range of 140° C. to 250° C.; collecting a first distillation fraction of the dicyclopentenyl ester; and then collecting a second distillation of the dicyclopentenyl ester; wherein the level of dicyclopentenyloxy(meth)acrylate in the second distillation fraction is in the range of 0 to 0.2 weight %, based on the weight of the dicyclopentenyl ester in the second distillation fraction. The second distillation fraction provides a low odor composition of the dicyclopentenyl ester which is useful as a reactive coalescent.
