The paper considers application of the interval analysis procedures to estimation of parameters of an experimental chemical process under conditions of corruption, uncertainty of errors probability characteristics, and short sample of measurements. For these reasons, application of the standard statistical approach is hampered; especially, it becomes impossible to determine accurately the confidential intervals for parameters of the process. Under such conditions, namely methods of the interval analysis can work reliably giving exact set of the admissible values of the parameters to be estimated. Such a set is very necessary for researches for proper organization of corresponding technological processes by correct choice of the parameters. In the investigation, existing interval analysis procedures were advanced and arranged for processing a concrete experimental data. As a comparison, approximate estimations of parameters have been calculated by the standard statistical approach. It is shown that the standard approach gives practically senseless estimations of the process parameters.
