PREDICTION OF THERMODYNAMIC CONDITIONS FOR NITROESTER VAPOR CONDENSATION ON THE SURFACES OF PROCESS APPARATUS DURING THE PRODUCTION OF ENERGETIC MATERIALS

摘要

A calculation procedure has been developed for finding thermodynamic conditions under which nitroglycerine, diethylene glycol dinitrate, and triethylene glycol dinitrate vapors are condensed on the surfaces of process apparatus during the production of energetic materials. Temperature - (plasticizer content in dry air) diagrams have been calculated and mapped. The diagrams allow one to estimate the condensation temperature of supersaturated nitroester vapor and to calculate the condensate weight. A procedure has been proposed for measuring the partial saturated vapor pressure of a plasticizer under the production conditions.
