Abstract: By use of the nonlinear functional analysis approach-the method of adjoint operators, the sensitivity analysis for CO coupling is comprehensively carried out in order to reveal important parameters in the research of reaction mechanism and in the design and operation of a tubular reac tor for synthesis of diethyl oxalate on the basis of the simplified mathematical reactor modei. The influence of operating and kinetic parameter variations from their nominal values on conversion and reactor bed temperature profile is cliscussed. The results provide an effective approach to the opti mal control for existed industrial plants and the identification of reaction mechanism.
