    摘要： This invention provides a method for purifying a chlorine supply that includes a chlorine component, a bromine component, and nitrogen trichloride. The method includes the steps of introducing the chlorine supply into a vaporizer, heating the chlorine supply in the vaporizer to form a vapor, and introducing the vapor into a distillation system to provide purified chlorine gas, a distillate that includes liquid chlorine and the bromine component, and a bottoms component including the nitrogen trichloride. The method also includes the steps of condensing the vapor in a reflux condenser, heating the condensate in a reboiler, removing the purified chlorine gas from the distillation system, and removing the distillate from the distillation system.

    摘要： A polyether polycarbonate block copolymer nonionic surface-active agent and method for making the same. The polyether polycarbonate surface active agent is comprised of a hydrophilic portion comprised of a polymer selected from the group consisting of a polyoxyalkylene polyether, a saccharide, a saccharide polyoxyalkylenate, a polycarbonate having a carbon dioxide content of from about 1 to 15 molar percent and mixtures thereof and a hydrophobic portion comprising alkylene and carbonate units arranged in alternating or random order to form a poly(alkylene carbonate) having a total carbon dioxide content of from about 25 to 50 molar percent and a total molecular weight of from about 300 to 10,000. The hydrophobic portion is bonded to the hydrophilic portion at each side of a reactive hydrogen. The surface active agent is prepared by polymerizing the hydrophilic portion with the hydrophobic portion in a weight ratio of about 10:90 to 90:10.

    摘要： There is now provided a method of recycling toluenediisocyanate residue resulting from the production of toluenediisocyanate by the reaction of toluenediamine by phosgenation in the presence of a solvent. In accordance with the teachings of the present invention, the toluenediisocyanate residue is treated at reflux with an alkanolamine to obtain an intermediary product which is distilled thereby giving rise to various products including but not limited to at least one component selected from toluenediamine, oxazolidone and hydroxyethylimidiazolidone. Preferably the alkanolamine employed is a monoethanolamine.
