Storage and safe delivery of hazardous speciality gases by acid/base reactions with ionic polymers

摘要

Basic gases having a proton affinity of less than 866 kJ/mol are stored for subsequent dispensing by contact with a support including at least one polymer sufficiently acidic to protonate the basic gas is contacted with the basic gas to protonate the basic gas. The protonated basic gas condenses to form a solid salt which is sorbed by the support. The basic gas is dispensed by deprotonating the sorbed solid salt to regenerate said basic gas. The invention is especially useful for storing, transporting and delivering hazardous basic gases, such as arsine and phosphine.
