Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol [7]) with the formula (CH 2 OH) 2.It is mainly used for two purposes: as a raw material in the manufacture of polyester fibers and for antifreeze formulations.
Ethane-1,2-dithiol, also known as EDT, [1] is a colorless liquid with the formula C 2 H 4 2. It has a very characteristic odor which is compared by many people to rotten cabbage . It is a common building block in organic synthesis and an excellent ligand for metal ions.
A major industrial route involves the reaction of acetaldehyde and acetic anhydride in the presence of a ferric chloride catalyst: [1] [2] CH 3 CHO + (CH 3 CO) 2 O → (CH 3 CO 2 ) 2 CHCH 3 It can be converted to the valuable monomer vinyl acetate by thermal elimination of acetic acid :
Contraindicated in pregnancy: Studies in animals or humans have demonstrated fetal abnormalities and/or there is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience, and the risks involved in use of the drug in pregnant women clearly outweigh potential benefits.

Glycol ethers are designated "E-series" or "P-series" for those made from ethylene oxide or propylene oxide, respectively.Typically, E-series glycol ethers are found in pharmaceuticals, sunscreens, cosmetics, inks, dyes and water-based paints, while P-series glycol ethers are used in degreasers, cleaners, aerosol paints and adhesives.
As interest in taking glucagon-like peptide-1 receptor agonist (GLP-1 agonist) medications, such as Zepbound and Wegovy, for weight loss, research continues to examine potential new side effects ...
Many syntheses have been developed. One popular route entails reduction of benzoin using zinc amalgam. [6]C 6 H 5 –CH(OH)–C(=O)–C 6 H 5, trans-C 6 H 5 –CH=CH–C 6 H 5. Both isomers of stilbene can be produced by decarboxylation of α-phenylcinnamic acid, trans-stilbene being produced from the (Z)-isomer of the acid.
