Studies on the Preservative (II)

Changes of Nitrofuran Derivatives in Course of Time under Various Conditions

Abstract

Effects of exposing the chemical to the sun's rays and heating in neutral, alkaline and acidic solutions on the decomposition of AF-2 (2-(2-furyl)-3-(5-nitro-2-furyl) acrylamide), NFS (5-nitro-2-furfuralsemicarbazone) and NFA (5-nitro-2-furylacrylamide) were studied.
The preservatives were decomposed easily, especially in alkaline solution, but AF-2 was more stable than the others.
Mixture of the preservatives exposed to the sun's rays were thin layer chromatographed for seperation and identification of themselves and their decomposition products.
The results obtained were shown in Figs. 1-7 and Table 1.
