Leírás

Általános leírás

2-Methyl-1-propanol can be obtained via hydroformylation of alkenes with fuel gas mixture in particular, carbon monoxide being the main reactant.

2-Methyl-1-propanol is a potential biofuel, which can be obtained as a major product in the yeast, Saccharomyces cerevisiae using glycine as a substrate through the glycine degradation pathway. It can also be obtained from the disaccharide, cellobionic acid (CBA) in Escherichia coli, via the ascB gene, which is primarily responsible for the CBA metabolism in E.coli.

Alkalmazás

2-Methyl-1-propanol may be used as an analytical reference standard for the quantification of the analyte in environmental samples using gas chromatography-optical fiber (GC-OF) technique and the obtained analytical results were compared with gas chromatography-flame ionization detector (GC-FID) technique. It may also be used as an analytical reference standard for the quantification of the analyte as decomposition products of alkyl nitrites in biological fluids using capillary gas chromatography (GC) with cryogenic oven trapping.
