[Alcoholic fermentation in "Schwabischen Most": ethanol and alcoholic congener alcohols]
1Institut für Gerichtliche Medizin, Universität Tübingen.
Abstract:
The concentrations of ethanol and congener alcohols in "Schwäbischer Most" were determined (1) at various stages throughout the fermentation process in two different types of "Most", and (2) after completed fermentation in eleven different types. The fermentation process was finished after about five weeks with a final ethanol concentration of 35-54 g/l. According to the congener alcohols the different specimens of "Most" could be classified as beverages like wine. However, the concentrations were found to vary so widely that the analysis of the beverage in question is to be recommended whenever an expert opinion is given. Our studies suggest that the alcohol concentrations do not change significantly, when the fermentation process has been finished.

Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.
Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
