Abstract
The feasibility of using macrocyclic ether - alkali metal salt complexes to effect the rapid destruction of the chemical warfare (CW) agents HD, GF and VX at or near room temperature, in non-aqueous solvents has been examined. An investigation of the decontamination efficiency of complexes formed by the macrocyclic ethers, 15-crown-5, 18-crown-6 and cryptand (2.2.2) in conjunction with inorganic salts such as alkali hydroxides, potassium superoxide, potassium dichromate and potassium acetate has been made. Agent destruction levels exceeding 80% were effected within 2-5 minutes at room temperature by several of the systems examined. Cryptand (2.2.2) was the most effective of the macrocyclic ethers in facilitating agent destruction. Generally, the relative ease of destruction of agents by the macrocyclic compounds followed the order HD > VX > GF.
