摘要
研究了用盐酸羟胺测定润滑油中糠醛含量的方法。经过试验表明 ,用醇 -苯 (1∶4 )混合液作溶剂 ,加入适量的盐酸羟胺 ,在 0℃～ 6 0℃下 ,反应时间在 15min以上 ,测定结果较为准确。
A study is made on the determination of furfural content in lubricating oil by the use of oxammonium hydrochloride.Experiments show that more accurate determining result can be obtained by adding proper amount of oxammonium hydrochloride to the solvent of alcohol-benzene mixture(1∶4) at 0～60℃ with more than 15 minutes of reaction.
