Abstract : two important factors, the loss of the catalyst components and the change of the catalyst particle diameter, which lead to the decay of the catalyst for amination of fatty alcohols, were studied. the dimension analytic method is applied successfully to determine the relations among the components loss, the particle diame - ter and the times of the catalyst used in repeated experiments
