General description

1-Butanol is a linear alcohol. Its biosynthesis from glucose using a bioengineered Escherichia coli strain has been reported. Its reaction with diisocyanates in the presence of triethylamine (catalyst) has been investigated by volumetric method. Kinetic studies suggest that the reaction proceeds via competitive consecutive second order. Its dehydration reaction has been employed as a standard reaction to evaluate the acidic and basic characteristics of various silica-aluminas.

Application

1-Butanol may be used for the solid acid (an acidic salt of H3PW12O40, Cs2.5H0.5PW12O40) catalyzed esterification of acrylic acid. It may be used as a cosolvent to investigate the enantioselective separation of racemic cyclohexyl methylphosphonofluoridate (cyclosarin, GF) by an chiral supercritical fluid chromatographic (SFC) technique.
Suitable for HPLC, spectrophotometry, environmental testing

Chemical warfare nerve agents (CWNAs) are extremely toxic organophosphorus compounds that contain a chiral phosphorus center. Undirected synthesis of G-type CWNAs produces stereoisomers of tabun, sarin, soman, and cyclosarin (GA, GB, GD, and GF, respectively). Analytical-scale methods were developed using
