Abstract
The article presents the results of a study of some regularities of the process of catalytic oxidation in the gas phase of methanol to formic acid. To do this, first, experiments were carried out on a unique laboratory setup at the nodal values of the initial parameters, and then a multiple regression equation for the process was created, the coefficients of the equation were calculated and their significance was determined. The adequacy of the equation was checked and a more sensitive parameter was identified. Using Fisher's criterion, the statistical significance of the equation was proved. Statistical analysis of the obtained regression equation was carried out: checking the significance of the equation and its coefficients, studying the absolute and relative errors of approximation. Paired correlation indicators of the equation coefficients are also calculated. Based on the maximum correlation coefficient, it was concluded that changes in the temperature of the reaction medium have the greatest effect on the yield of formic acid. It was also found that the parameters of the model are statistically significant.
Keywords: methanol, formic acid, catalytic oxidation, regression equation, pair correlation.
