O-methoxyacetanilide nitration reaction thermal safety risk assessment method

Abstract

The invention provides an o-methoxyacetanilide nitration reaction thermal safety risk assessment method, and relates to the technical field of nitration processes. The o-methoxyacetanilide nitration reaction thermal safety risk assessment method comprises the following steps: step 1, testing the thermal stability of a material; step 2, reaction calorimetry test of nitration reaction; step 3, secondary decomposition test of nitration reaction completion liquid; and 4, carrying out nitration reaction safety risk assessment. A safety risk assessment model for nitration reaction heat of o-methoxyacetanilide is established through technical contents, and effective technical support and guarantee can be provided for production process heat safety and production safety accident prevention of a nitration process according to an assessment result. The method is of great significance to safety production and major accident prevention and control in the chemical industry.

Description

technical field [0001] The invention relates to the technical field of nitration technology, in particular to a thermal safety risk assessment method for nitration reaction of o-methoxyacetanilide. Background technique [0002] my country's chemical industry has already become a pillar industry of the national economy. There are a large number of chemical enterprises, the reaction types involve a wide range, and the production equipment and processes are complex and changeable. At the same time, most of the raw materials, intermediate products, products and wastes involved in the production process are flammable, explosive or toxic, harmful and corrosive. . These characteristics of chemical production determine that the possibility of production safety accidents is high, and the consequences of accidents are serious. In addition to causing a large number of direct losses such as casualties and property losses, they may also have a profound negative impact on the environment...
