Individuals with alcohol use disorder may consume ethanol-based hand sanitizer, especially during withdrawal. Increased availability of hand sanitizers in healthcare settings poses a risk for alcohol-seeking behaviors.
Area of Science:
- Toxicology
- Addiction Medicine
- Emergency Medicine
Background:
- Ethanol intoxication is a common cause for emergency department (ED) visits.
- Alcohol use disorder patients may seek ethanol during withdrawal, sometimes using hand sanitizer.
- Increased use of ethanol-based hand sanitizers during the COVID-19 pandemic raises concerns.

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...
