摘要
本文报道在实验室合成的过氧乙酸原液中分别加入0.1%(W/V)8-羟基喹啉,0.5%(V/V)磷酸和0.5%(W/V)焦磷酸钠作稳定剂。通过一年左右贮存和定期测定过氧乙酸百分含量;并作了不同含量磷酸以及0.5%(V/V)磷酸对用不同配方配制的过氧乙酸的稳定性的研究。结果表明,0.1%、0.3%和0.5%(V/V)的磷酸以及0.5%(W/V)焦磷酸钠对过氧乙酸原液均无稳定作用。故认为,贮存过氧乙酸原液不宜以磷酸或焦磷酸钠作稳定剂。
This paper reports the ef-fectiveness of 0.1%(W/V) quinolin-8-ol, 0.5%(V/V)phosphoric acid and 0.5%(W/V)sodium pyrophosphate as stabilizers ofstock solutions o? peracetic acid. The threesolutions were put separately as stabilizersinto stock solutions of peracetic acid in thelaboratory. They were stored at room tem-perature for approximately one year,andthe percent of peracetic acid content wasdetermined at regular intervals. Also, wemade studies on different concentations ofphosphoric acid for different prescriptionsof peracetic acid. The results show that0.1%, 0.3% and 0.5%(V/V) phosphoric acidand 0.5% (W/V) sodium pyrophosphatewere not effective stabilizers for the stocksolutions of peracetic acid. Therefore, phos-phoric acid or sodium pyrophosphate isnot an effective stabilizer in stockpilingstock solutions of peracetic acid.
