Determining the Hydrogenation Condition of Oil & Fats by the Orthogonal Table L₈(2⁷)

The purpose of this paper is on determining the optimum hydrogenation conditions of oil & fats of toilet soap for improving the process capability and quality. This paper employs the orthogonal table $L_8(2^7)$ The result of this paper is as follows: (1) The optimum condition of hydrogenation is determined as $A_1$, $B_2$, $C_2$, $D_2$ and the presumed value of average melting point is $42.54{\pm}1.70$(${\alpha}=0.05$) (2) The index of process capability(Cp)is improved from 0.50 to 1.39.
