摘　　要：研究了间甲酚直接氧化合成间羟基苯甲醛产品的检出与测定方法 ,研究表明 ,采用电位滴定法进行测定 ,方法简便易行 。A method of determination of 3-hydroxybenzaldehyde as the main product of its synthesis is reported. It is found that the use of potentiometric titration is more feasible and convenient for this purpose, because the interference from the deep background color can be overcome in this way. It is proved by the experimental results that the accuracy and precision are satisfactory and conform to the requirements of chemical production.
