Abstract

Pyridinoline photo-degraded with the formation of photoproducts absorbing diffusely around 260-290 nm (pH 7) and sharply at 232 nm (pH 1). Subsequent heating partially regenerated the original pyridinoline, also producing new products absorbing at 417/440 nm (pH 7) and 300/412 nm (pH 1). Pyridinoline (pH 7) and its new products (pH 7 and pH 1) also underwent ozone-induced degradation.

摘要

吡啶啉发生光降解，形成在260 - 290nm附近（pH 7）有漫反射吸收且在232nm处（pH 1）有尖锐吸收的光产物。随后加热使部分原始吡啶啉再生，同时还产生在417/440nm（pH 7）和300/412nm（pH 1）处有吸收的新产物。吡啶啉（pH 7）及其新产物（pH 7和pH 1）也会发生臭氧诱导的降解。
