Beschreibung

Anwendung

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.
