(fatty mixture of C13-C15 purchased from Phillips Chemical Company). The mixture solution was heated to 165° C. for 7 hours and then 2.5 L Soltrol/70.(R). was added. The temperature of the mixture solution was lowered to 154° C. to filter inorganic solids and to obtain a filtering liquid. 2 L of methanol was added to the filtering liquid to accelerate crystallization of the benzidine compounds. Then, the filtering liquid was filtered again to obtain a yellow solid, which is a crude mixture of three types of benzidine compounds. Moreover, 2 L of methanol dissolved the crude mixture of benzidine compounds and filtered by 1.2 Kg of Woelm neutral alumina to obtain a light-yellow solid. Lastly, n-octane was used to dissolve the light-yellow solid and to re-crystallize the benzidine compounds in the form of white crystal. The white crystal weighed 500 g, has a melting point range of 168-170° C., and is a final mixture of the benzidine compounds having high purity.

The m-xylene solution was filtered by 600 g of Woelm neutral alumina to obtain a filtering liquid. Then, the filtering liquid was dried to obtain 630 g of a crude mixture of benzidine compounds in the form of a yellow solid.

The flask was immersed in a 165° C. oil bath and the two-phase melt was stirred for 3 hours. Hot (140° C.) Soltrol.(R). 170 was added and the inorganic solid separated by vacuum filtration. On cooling, the product crystallized from the filtrate and was isolated in 89percent yield by filtration. Purification was accomplished by slurrying the product with neutral alumina (10 grams) in 1 liter of Soltrol.(R). 170 at 150° C. for six hours, the alumina was removed by filtration and the purified product crystallized from the filtration on cooling. Isolation by filtration was accomplished with a 95percent recovery of the product.
