Solubility of 1,3-butadiene and methyl propene in n-methyl-2-pyrrolidone

The solubility of 1,3-butadiene and methyl propene in pure and aqueous solutions of n-methyl-2-pyrrolidone was measured at different pressures and temperatures. A simple weighing method was used to measure experimental data. Using these experimental results, the parameters of Wilson's correlation were estimated and tested at other experimental conditions. The results were satisfactory.
