A novel approach is devised to inspect the influence of universal solvent, ethyl alcohol, when mixed with Casson fluid across an exponentially stretching sheet, involving radiation absorption and chemical reaction. At the boundary, slip conditions are additionally considered. Utilizing appropriate similarity transformation, the governing partial differential equations are transfigured into a system of coupled ordinary differential equations. Subsequently, the resulting equations are solved numerically using MATLAB built-in technique bvp4c. Graphical results are presented for the gaseous and liquid state. The effect of pertinent parameters on the skin friction coefficient, heat and mass transfer rates are elucidated in tabular form. Furthermore, comparisons of the present results with previously published work show that the present results have high accuracy. It is noteworthy to mention that the combined effect of radiation absorption and slip conditions enhances the temperature distribution near the wall and suppresses it away from the wall in the case of Casson fluid blended with ethyl alcohol. Also, the effect of the chemical reaction parameter on the mass transfer rate is very influential. The present study is of immediate interest in biodiesel production, which serves as an attractive alternative to conventional petroleum diesel fuel.
