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. It is an odorless, colorless, flammable, viscous liquid.
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.
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.
Ethylene glycol dimethylacrylate (EGDMA) is a diester formed by condensation of two equivalents of methacrylic acid and one equivalent of ethylene glycol. [2]EGDMA can be used in free radical copolymer crosslinking reactions.
Ethylene glycol dinitrate is a colorless volatile liquid when in pure state, but is yellowish when impure. Molar weight 152.07, N 18.42%, OB to CO 2 0%, OB to CO +21%; colorless volatile liquid when in pure state; yellowish liquid in crude state; sp gr 1.488 at 20/4° or 1.480 at 25°; n_D 1.4452 at 25° or 1.4472 at 20°; freezing point -22.75° (versus +13.1° for NG); frozen point given in ...
The orally lethal dose in humans has been reported as approximately 1.4 mL/kg of pure ethylene glycol. [7] That is approximately 224 mL (7.6 oz.) of 50% ethylene glycol for an 80 kg adult and 56 mL (2 oz.) for a 20 kg child.
A 2019 study published in JAMA Pediatrics, for example, found that IQ levels were slightly lower in 3- and 4-year-old children whose mothers had higher measures of fluoride in their urine when ...
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
