Mathematical model of sulphomethylation process of nonylphenol

Abstract

This paper concerns the development of the mathematical model of sulphomethylation process of nonylphenol based on planning of the experiment. While developing the mathematical model of the process, a method of gross factor experiment (GFE), realizing all possible combinations of the factors chosen, was used by us. By varying four factors on two (minimum and maximum) levels, the experimental values of yields of the product required (sodium sulphate of hydroxynonylbenzyl sulphonic acid), were obtained. The coefficients of regression equations $B_i$ are calculated by scalar products. Then the adequacy of the mathematical model was checked. Thus, a mathematical model of the sulphomethylation process of nonylphenol in the full scale of coordinates was obtained.
