标 题 :Synthesis of aldonolactones, aldarolactones, and aldarodilactones using azeotropic distillation
发明人：CHENAULT HENRY K
权利人:CHENAULT HENRY K
摘要:Processes for making lactones and dilactones from aldaric acids, aldonic acids, and their corresponding salts by dehydrative cyclization and azeotropic distillation. The processes can be carried out in the presence of water because water is removed by azeotropic distillation.
