Factors affecting carbone preservative
1. PH value: The stability of casson will be affected in alkaline medium with PH value greater than 9.
2. Temperature: failure rate at 50℃ for 10 minutes is 5.5%, 30 minutes is 6.3%; The failure rate at 100℃ is 6.2% for 10 minutes and 8.1% for 30 minutes. The failure rate at 120℃ is 9.0% for 10 minutes and 15.9% for 30 minutes.
3. Monovalent sodium and potassium ions have no effect on the stability of cassone; Divalent magnesium ions, calcium ions and copper ions have protective effects on the stability of cassone, and the protective ability is copper ions, magnesium ions and calcium ions in order from strong to weak. The trivalent iron ion has a destructive effect on the stability of casson, so in the storage process can not contact with reducing metals, such as metal iron, aluminum, so as to avoid product decomposition.
4. The combination of strong nucleophilic chemicals with this product, such as mercaptans, amines, thioethers, thiosulfates, strong reducing agents (sodium sulfite and bleach), such as S2- and R-NH2, will lead to quality degradation or even complete failure of this product.
