It is a colorless liquid with a sharp, sweet odor. It is also known as methyl ethyl ketone (MEK). 2-Butanone is produced in large quantities. Nearly half of its use is in paints and other coatings because it will quickly evaporate into the air and it dissolves many substances. It is also used in glues and as a cleaning agent.
La masse molaire des composés est égale à la somme des masses molaires des atomes qui forment le composé. Utiliser le convertisseur Calculateur de masse molaire Ce convertisseur d’unité en ligne permet d''obtenir des conversions rapides et précises de différentes unités de mesure d''un système à un autre.
The molar masses of carbon, hydrogen, and oxygen are 12.0107 g/mol, 1.00794 g/mol, and 15.9994 g/mol, respectively. These values can be determined by multiplying the standard atomic weight for each element by the molar mass constant. Next, we can multiply these values by the frequency of each element, so: 12.0107 × 6 1.00794 × 12 15.9994 × 6
4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is a genotoxic carcinogen found in tobacco and tobacco smoke. Several in vitro and in vivo assays have been used for evaluating the genotoxicity of tobacco smoke and tobacco smoke constituents like NNK, yet it is not clear which in vitro assays are most appropriate for extrapolating the in vitro responses of these test agents …

Different strains have been engineered for the production of butanone and 2-butanol (Table 12.2).Because meso-2,3-butanediol is the direct precursor of butanone and 2-butanol, a strain that can natively produce meso-2,3-butanediol is preferred. There are several industrial strains that can produce meso-2,3-butanediol with high tiers, such as K. pneumoniae, K. oxytoca, …
