| titleOfInvention | Method for measuring nitration reaction heat effect in nitro energy compound preparation process |
| abstract | The invention discloses a method for measuring a nitration reaction heat effect in a nitro energy compound preparation process. The method comprises the following steps: firstly, measuring a total heat effect delta<r>H<m> in an energy material preparation process and a heat effect delta<r>H<m,2> of equivalent produced water, for nitration reaction, and concentrated acid reaction under the same condition through a calorimetric experiment, wherein the difference value between the delta<r>H<m> and the delta<r>H<m,2> is the measured nitration reaction heat effect delta<r>H<m,1> in the energy material preparation process; calculating a nitration reaction heat effect delta<r>H'<m,1> in the energy material preparation process by adopting different quantum chemistry methods; selecting the quantum chemistry method through which the relative error between the delta<r>H'<m,1> and the delta<r>H'<m,1> is the minimal as the calculation method for the nitration reaction heat effect in the corresponding energy material preparation process; and then calculating the nitration reaction heat effect delta<r>H<m,1>(T) in the energy material preparation process at a target temperature T according to an optimization method. The invention provides an effective method for measurement of the nitration reaction heat effect in the nitro energy compound preparation process. A basis is provided for design of a heat exchanger and selection of an appropriate processing parameter in related energy material research and production processes. |
