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 ...
The Ziegler alcohol synthesis involves oligomerization of ethylene using triethylaluminium followed by oxidation. [2] The triethylaluminium is produced by action of aluminium, ethylene, and hydrogen gas. In the production process, two-thirds of the triethylaluminium produced is recycled back into the reactor, and only one-third is used to ...
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
The reaction is an example of cross metathesis. The utility of the reaction is driven by the low cost of ethylene as a reagent and its selectivity. It produces compounds with terminal alkene functional groups (α-olefins), which are more amenable to other reactions such as polymerization and hydroformylation. The general reaction equation is:
Alcohol is also converted into phosphatidylethanol (PEth, an unnatural lipid metabolite) by phospholipase D2. This metabolite competes with PIP 2 agonist sites on lipid-gated ion channels. [28] [29] The result of these direct effects is a wave of further indirect effects involving a variety of other neurotransmitter and neuropeptide systems. [25]
The Wacker reaction was first reported by Smidt et al. [3] [4] [5] The development of the chemical process now known as the Wacker process began in 1956 at Wacker Chemie. [6] At the time, many industrial compounds were produced from acetylene, derived from calcium carbide, an expensive and environmentally unfriendly technology.
In the IUPAC system, the name ethylene is reserved for the divalent group -CH 2 CH 2-. Hence, names like ethylene oxide and ethylene dibromide are permitted, but the use of the name ethylene for the two-carbon alkene is not. Nevertheless, use of the name ethylene for H 2 C=CH 2 (and propylene for H 2 C=CHCH 3) is still prevalent among chemists ...
Alkoxylation is a chemical reaction that involves the addition of an epoxide to another compound. The usual manifestation of this reaction is ethoxylation of alcohols (ROH), in which case ethylene oxide is the alkoxylating agent: ROH + C 2 H 4 O → ROCH 2 CH 2 OH. Another industrially significant epoxide is propylene oxide (PO, OCH 2 CHCH 3 ...
