DECARBOXYLATION OF ROSIN ACIDS

摘要

DECARBOXYLATION OF ROSIN ACIDS There is disclosed a process for the preparationof thermal oils which comprises heating rosin acids to a temperature from 300-360.degree.C in the presence of at least one decarboxylation accelerator selected from the group consisting of high sulfur content tall oil rosin, VinsolTM resin, fatty acids, organic sulfides and inorganic sulfides. The process of this invention provides an economical and efficient method of treating a renewable hydrocarbon feedstock to produce a material that is suited for numerous applications, especially in rubber formulations.
