摘要:
The present invention is for extremely pure solutions of chlorine dioxide, methods for making such solutions and to compositions and methods for storing, shipping and using such solutions. Generally, the chlorine dioxide solutions of the invention are aqueous solutions containing about 2500 ppm or less of total impurities. The chlorine dioxide solution can be prepared by passing dilute highly pure chlorine gas through a bed of substantially solid sodium chlorite and contacting the resulting chlorine dioxide gas with a liquid.

摘要:
New compositions and methods are disclosed for decontaminating surfaces and enclosures that avoid problems such as salt deposits, corrosion and condensation that accompany the use of known methods. The process involves the use of chlorine dioxide solutions prepared by passing dilute chlorine gas over solid granular sodium chlorite to produce chlorine dioxide gas which is then collected in solution. The chlorine dioxide gas can be introduced into an enclosure and used to disinfect a portion of the contents of the enclosure.
摘要:
An improved method of processing a nonferrous metal and alloys of said metal using a blanketing gas having a global warming potential is provided. The improvement involves reducing the global warming potential of the blanketing gas by blanketing the nonferrous metal and alloys with a gaseous mixture including at least one compound selected from the group consisting of COF2, CF3COF, (CF3)2CO, F3COF, F2C(OF)2, SO2F2, NF3, SO2ClF, SOF2, SOF4, NOF, F2 and SF4.
