说明

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.

Knoevenagel Condensation Reaction

Knoevenagel Condensation is an organic reaction named after Emil Knoevenagel. It is a classic C-C bond formation reaction and a modification of the Aldol Condensation.

Synthesis of 2-amino-3-cyano-4H-chromen-4-ylphosphonates and their anticancer properties.

Reddi Mohan Naidu Kalla et al.

European journal of medicinal chemistry, 76, 61-66 (2014-02-27)

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

Dry sampling of gas-phase isocyanates and isocyanate aerosols from thermal degradation of polyurethane.

Daniel Gylestam et al.

The Annals of occupational hygiene, 58(1), 28-49 (2013-08-21)

The performance of a dry sampler, with an impregnated denuder in series with a glass fibre filter, using di-n-butylamine (DBA) for airborne isocyanates (200ml min(-1)) is investigated and compared with an impinger flask with a glass fibre filter in series

Heparin-like glycosaminoglycan/amine salt-bridge interactions: a new potential tool for HLGAGs analysis using mass spectrometry.

Baiyi Xue et al.

Journal of mass spectrometry : JMS, 46(7), 689-695 (2011-07-12)

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
