processo para obter neopentil glicol por craqueamento de substância de alta ebulição que ocorrem no processo de produção

摘要

The present invention relates to a process for obtaining neopentyl glycol by hydrogenating cracking of high-boilers occurring in the production process in the presence of copper-chromite catalysts. The hydrogenating cracking proceeds in the absence of solvent at a temperature of 140 to 220° C. and at pressures of 7 to 28 MPa.
