Abstract:Three methods for measure of saponification value of cane wax, including the National standard method, the conductometric titrimetry and the pH value titrimetry, were investigated here. Besides, the operating conditions of the conductimetric titrimetry and the pH value titrimetry were mainly discussed. It was found that Using the conductimetric titrimetry or the pH value titrimetry could effectively avoided the influence of the color of cane wax and the corresponding measuring results were accurate with a good relativity.
