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. 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 (acidic salt of H3PW12O40, Cs2.5H0.5PW12O40) catalyzed esterification of acrylic acid.
