There are problems of destruction of educational and simulation formulations and components of special chemical-based products and degassing formulations based on organic solvents. Their solution requires the search for cost-effective and environmentally friendly solutions and approaches to their disposal, especially paying attention to the fact that it is practically impossible to completely free the components of products from toxic chemicals. In turn, it is necessary to minimize toxic and unpleasant-smelling emissions into the atmosphere during neutralization and destruction. The purpose of the work is to propose chemical methods for neutralizing and disposing of toxic substances and foul-smelling compounds during the disposal of educational and simulation formulations and special tools. To neutralize compositions based on odorant substances, it is advisable to use compounds of oxidizing-chlorinating action, quaternary ammonium bases and a co-catalyst. The role of each of the used components of the formulation is established. Sodium hypochlorite is an oxidizer, «Katamin AB» is an interphase transfer catalyst that ensures the transfer of anion from the aqueous phase to the organic one, methanesulfonic acid is a co-catalyst that ensures the reaction in both the aqueous and organic phases. The optimal quantitative and qualitative composition of the degassing formulation for neutralizing odorants is considered. The composition of the formulation should include the following components, expressed in % by weight: an aqueous solution of sodium hypochlorite (5%) «Whiteness» – 99.0; dimethylalkyl(C8 -C18) benzylammonium chloride «Katamin AB» – 0.5; methanesulfonic acid – 0.5. |
