53 Methodology. Review of literary sources, analysis of identified trends and patterns. Results. Based on the analysis of literature sources, it was found that peroxycarboxylic acids, in particular, peroxyacetic acid or m -chloroperoxybenzoic and peroxomonosulfate, have an abnormally high reactivity in electrophilic substitution reactions. It was shown that they can be an effective component of sulfur or nitrogen mustard decontamination systems . Scientific novelty . The anomalous nature of the reactivity of peroxyacids in sulfur or nitrogen mustard decontamination systems is described. It is concluded that they are among the most active electrophiles available for creating green decontamination systems. Practical significance . The use of peroxyacids in modern systems for the decontamination of toxic sulfur and nitrogen mustards will significantly increase the efficiency of decontamination processes and their environmental friendliness. Keywords: peracetic acid, m-chloroperoxybenzoic асіd, peroxomonosulfate, reactivity, decontamination, sulfur and nitrogen mustards, sulfur mustard sulfoxide, N-oxide nitrogen mustard. Currently, the Armed Forces are armed with a variety of armored vehicles, which are the most reliable mobile means of protection against weapons of mass destruction and are capable of performing combat tasks in the conditions of the use of nuclear, chemical and biological weapons. Standard formulations of special processing, which have been in service for more than 70 years, under modern conditions do not meet the requirements of speed and completeness of the process, have a significant corrosive effect on structural materials (steel, paint and varnish materials, rubber, plastics) and are toxic and flammable. The instructions for the special processing of weapons and military equipment indicate the need to lubricate the treated surfaces with lubricants after degassing.
