Dynamic behaviour of 1-aminopropan-2-one in sewage: a preliminary synthetic and spectroscopic study

A preliminary investigation of the solution phase behaviour of the biomarker compound 1-aminopropan-2-one (APR) using NMR spectroscopy was carried out. This was achieved, in part, by synthesis of APR with¹³C-enrichment in the methylene position. In this paper, we report that this biomarker undergoes H/D exchange with D₂O, probably via an enol intermediate. In addition, use of¹³C-enriched APR enabled its detection by¹³C NMR spectroscopy at environmentally relevant concentrations.     

磺化酞菁铁的合成与光催化降解染料废水的研究

采用邻苯二氰方法合成了酞菁铁（FePc)配合物，后又经碘化得磺化酞菁铁（FePcSx），以其作为催化剂利用过氧化氢（H2O2）对模拟染料废水活性艳红X－3B进行光催化降解脱色试验（λ＞320nm)，结果染料废水的降解脱色率较高。并且通过与单独用过氧化氢降解进行对照，表明磺化酞菁铁具有很好的催化活性与优良的化学结构。     

Chemical synthesis of 6-pentyl-2H-pyran-2-one: a natural antifungal biosynthesized by Trichoderma spp.

Trichoderma spp. biosynthesize 6-pentyl-2H-pyran-2-one (6-PP), a natural antifungal pyrone which could be used as biological control agent (BCA). Unfortunately, biotechnical processes are limited by inhibition of biomass at high concentration of 6-PP. We report herein a new easy synthesis of this natural pyrone, using readily available starting materials. This synthesis, compatible with a large production scale, permit to obtain overweight amounts of 6-PP that in biotechnological routes.
