摘要

Process for obtaining purified au00e7u00facaranidro alcohol, alcohol of sugar anidropurificado, process for purification of u00e1lcooisde sugar anhydrous.Polu00ecmero, product, method for the determination of the adequacy of a month amid anhydrous alcohol for use in a polu00ecmero, mu00e9todopara determination of purity of a month amid anhydrous alcohol.Sugar alcohol, anhydrous, mu00e9todopara the formation of a polu00ecmero epoliu00e9ster isotropic polyester.This application relates to umprocesso for the formation of a sugar alcohol anidropurificado,By means of which the anhydrous alcohol of sugar purificadoresultante has a purity of at least 99.8% and u00e9substancialmente colourless.The sugar alcohol anhydrous is purificadoatravu00e9s distillation, recrystallization from methanol, ethanol ouetileno glycol, recrystallization by melting, or a combination of these.Preferably, the purification by distillation followed by porrecristalizau00e7u00e3o from methanol, ethanol or ethylene glycol.u00e9apresentado a test to determine the purity of the month amid anhydrous alcohol.In what is considered the color of alcohol of au00e7u00facaranidro after annealing at a temperature of at menos260 198 C for at least four hours.Alternatively, apureza can be determined by examination of the issue deultravioleta (UV) of sugar alcohol anhydrous purified vu00e1rioscomprimentos wavelength.The sugar alcohol anhydrous purified podeser incorporated into a polymer such as a polyester, which, in turn, can be used to form articles of manufacture taiscomo containers.Optical disks, fibers, sheets and films.
