Abstract:
Patients with alcohol use disorder experience frequently alcohol withdrawal syndrome (AWS), which is a potentially life-threatening condition mainly caused by glutamate overactivity. The aim of therapeutic alcohol withdrawal is the entry into a process of complete and lasting abstinence. Therefore preparing withdrawal is crucial to optimize compliance and efficacy of aftercare. Indeed, performing repeated withdrawal per se without any project of subsequent abstinence may be deleterious, at least because of repeated exposure to glutamate neurotoxicity. Managing AWS mainly consists in anticipating severe withdrawal, decreasing the risk of complications, making this experience as comfortable as possible, preventing from long-term benzodiazepine use, and enhancing motivation to aftercare and long-term abstinence. In particular, there are specific guidelines to choose which benzodiazepine administration approach to adopt (i.e. symptom-triggered, fixed schedule or loading dosage) and which other drugs to deliver (e.g. thiamine, folate, magnesium). Specific precautions should be taken in the elderly.

Oxidation of Alcohols
The process of oxidation in a chemical reaction is observed in any of the three forms:
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.
