Phenyllithium is an organometallic agent with the empirical formula C 6 H 5 Li. It is most commonly used as a metalating agent in organic syntheses and a substitute for Grignard reagents for introducing phenyl groups in organic syntheses. [ 3 ]
But when omitting alcohol from a drink you need to consider a range of factors: alcohol adds body and richness to drinks, it balances sweet flavors, and its astringency adds texture.
Even a few years ago, your options for alcohol-free drinks were pretty slim: maybe a sad mocktail, maybe a boozeless beer. Now, your choices range from non-alcoholic spirits to wine and ready-to ...
An alcohol-free or non-alcoholic drink, also known as a temperance drink, is a version of an alcoholic drink made without alcohol, or with the alcohol removed or reduced to almost zero. These may take the form of a non-alcoholic mixed drink or non-alcoholic beer , and are widely available where alcoholic drinks are sold.
Organolithium reagents are typically stored below 10 °C. Reactions are conducted using air-free techniques. [64] The concentration of alkyllithium reagents is often determined by titration. [66] [67] [68] Organolithium reagents react, often slowly, with ethers, which nonetheless are often used as solvents. [69]
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
Ethanol (data page) provides detailed information about the chemical properties, physical properties, and safety measures of ethanol.
pK a values of amino acid side chains play an important role in defining the pH-dependent characteristics of a protein. The pH-dependence of the activity displayed by enzymes and the pH-dependence of protein stability, for example, are properties that are determined by the pK a values of amino acid side chains.
