摘要
比较了乙酐 浓硫酸法和乙酐 吡啶法测定非离子表面活性剂羟值的效果 ,结果表明 :选择合适的测定条件 ,可以用乙酐 浓硫酸法代替乙酐
Comparing the results of hydroxy-value of nonionic surfactants Measured by acetic-anhydride～oil of vitriol process and acetic-anhydride-pyidin process,the results shown that acetic-anhydride～oil of vitriol process could replace acetic-anhydride-pyidin process.
