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.
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: (CH 3 CO 2) 2 CHCH 3 → CH 3 CO 2 CH=CH 2 + CH 3 CO 2 H
American law requires that certain drugs and biological products must be labelled very specifically. Title 21, Part 201.57 (9)(i) of the Code of Federal Regulations lists specific requirements regarding the labeling of drugs with respect to their effects on pregnant populations, including a definition of a "pregnancy category".
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.
