Abstract

This paper concerns the development of the mat 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 Bi are calculated by scalar products Then the adequacy of the mathematical model was checked Thus. a mathematical model of the sulphomethylation process l)f nonylphenol in the full scale of coordinates was obtained.

Highlights

\ hst n\ct: This paper concerns the de\'elopment of t he mat hematical model of sulphometll\'lation process of nonylphenol based on planning of the experiment While de\'eloping the mathematical model of the process. a method of gross factm experiment (GFE). realizing all possible combinations of the factors chosen. was used by us
It is known that sulphonate additives based on sulphonated alkvlphenols possess detergentdiapersi\·e. antioxidative and anticorrosion properties Initial alkylphenol is sulphonated mainly by oleum. concentrated sulphuric acid and sulphuric anhydride By saponitication of alkyl phenol sulphonic acids through oxides or hydroxides of alkaline-earth metals, etlicient sui phonates are obtained
The main shortcoming of these methods for obtaining the sulphonate additives considered is the application of aggressive reagents as sulphonating agents which lead to environmental contamination In addition. the sulphonation process promotes the formation of considerable amount (3S--l0%) of acid sludge requiring tllrther utilization . the gelatinous sludge, generated on neutralization step, does not dissolve in organic solvents
