Molar mass distribution of the polyoxyethylene derivatives of alcohols, alkylphenols and alkylamines

Numerical integration technique using the Runge‐Kutta method of the fourth order and optimization algorithms using the Monte Carlo method and the simplex Nelder and Mead method were applied for computing the distribution coefficients for polyoxyethylene derivatives of dodecanol, p‐t‐octylphenol and hexylamine. The validity of the proposed more general and quicker computing technique was proven.
