Dissecting the hindered rotation of ethane.
The existence of a rotational barrier of ca. 3 kcalmol 1 around the C C single bond in ethane has been known since the early studies of Ebert, Wagner, Eucken and Weigert and Pitzer done in the 1930s. Even the simplest ab initio methods are able to reproduce this fundamental result. However, the physical origin of this hindered rotation is still under controversy in the literature. There are two...
متن کاملHindered rotation in N-methylformamide. A peptide-bond model system.
Barriers to rotation about the C-N bond in the cis and trans isomers of N-methylformamide have been determined by n.m.r. spectroscopy. Representative values are 20.7 and 22.0 kcal/mole. Arrhenius parameters have also been determined. These results are compared with C-N barriers for N,N-dimethylformamide and unsubstituted formamide. The data suggest that C-N rotational barriers for N-methyl amid...
متن کاملFermentation ethyl alcohol.
Ethyl alcohol is produced in the United States by two major procedures, fermentation and chemical synthesis. Practically all current industrial ethyl alcohol is manufactured synthetically from petroleum and natural gas. All beverage alcohol is produced through the fermentation of cereal grains, molasses. and other materials with high starch and sugar content. Chemically, both alcohols are essen...
متن کاملThe Determination of Ethyl Alcohol*
Of the various chemical methods described in the literature for the determination of ethyl alcohol (1) the majority are based upon the oxidation of the alcohol to acetic acid by means of potassium dichromate in the presence of a high concentration of sulfuric acid. Typical of these methods are the ones devised by Widmark (2) and by Nicloux (3). Widmark reports that it is not possible to calcula...
متن کاملEthyl alcohol and the heart.
Since a significant fraction of the population are heavy consumers of ethanol, and recent postmortem studies suggest that most alcoholics have some degree of cardiac abnormality, elucidation of the basis for alcoholic cardiomyopathy is of some importance. Intoxicating amounts of ethanol depress ventricular function acutely and effect leakage of myocardial cell components. On the basis of studie...
