Use of the unique properties of fluoropolymers in the design of new,highly effective,ecologically friendly technologies for the fine purification of hydrogen halides and their aqueous solutions

摘要

A number of properties of fluoropolymers in aqueous solutions of hydrogen halides were investigated.The results enable fluoropolymers to be used in the purification of hydrogen halides and their aqueous solutions.The hydrophobicity of fluoropolymers and their diffusion permeability enable production of hydrogen halides of low moisture content.A second unit for hydroionic convection is based on hydroionic repulsion (determined by the hydrophobic properties of the fluoropolymer) and ionic elimination.The two units enalbe the highly effective,ecologically safe manufacture of highly pure hydrogen halides and their aqueous solutions to be carried out with minimum feedstock,cooling water,and power consumption.
