过氧乙酸贮存中稳定性的试验观察

Experimental Observation On Peroxyacetic Acid Stability in Storage

过氧乙酸贮存于１２℃以下的温度中，其稳定性好，其浓度不下降。在１２～１７℃温度中其浓度缓慢卜降。但在１７～２５℃的温度中其浓度不继续下降，仍然保持在１０．６４％的浓度。在３６℃高温环境中浓度是８．７４％，仍比消毒有效浓度高得多．总之，在相同的贮存温度和时间条件下，稳定剂８－羟基喹啉对过氧乙酸的稳定性没有影响。

The stability or peroxyacetic acid is high and the density of peroxyacetic acid will not decrease when peroxyacetic acid is stored below temperatures 12℃. The density of peroxyacetic acid decrease slowly between temperatures 12℃ and 17℃. But the density of peroxyacetic acid does not decrease continually between temperatures 17℃ and 25℃,and yet it keeps in density at 10.64%. The density or peroxyacetic acid is at 8.74% under the hot environment at temperatures 36℃, and it is much higher than the effective density of sterilization. Generally, the stability of peroxyacetic acid is not influenced by stabilizer 8-hydroxyquinoline under the same temperatures and time in storage.
