Application

Dibutylamine was employed as organocatalyst during the synthesis of 2-amino-3-cyano-4H-chromen-4-ylphosphonates via Knoevenagel, Pinner and phospha-Michael reactions. Di-n-butylamine (Dibutylamine) may be used to investigate the performance of a dry sampler, with an impregnated denuder in series with a glass fibre filter for airborne isocyanates. It was used in the preparation of 1M dibutylammonium phosphate buffer.

A series of 2-amino-3-cyano-4H-chromen-4-ylphosphonates have been synthesized by reacting substituted salicylaldehydes, malononitrile, and dialkylphosphites using a catalytic amount of dibutylamine as an organocatalyst employing Knoevenagel, Pinner, and phospha-Michael reactions simultaneously in ethanol. This protocol is an environmentally friendly procedure and

Characterization of glycosaminoglycans poses a challenge for current analytical techniques, as they are highly acidic, polydisperse and heterogeneous compounds. The purpose of this study is the separation and analysis of a partially depolymerized heparin-like glycosaminoglycan by on-line ion-pairing reversed-phase high-performance

N-nitrosodimethylamine (NDMA) as one emerging disinfection by-product has been investigated globally since 1990s. However, its main precursors are still unclear. We found that NDMA formation potential (NDMAFP) of various water samples increased firstly and then decreased gradually during incubation with
