Topic: Glycol ether


  
  Glycol Ethers
Some commonly used glycol ethers are listed on page 2, along with their abbreviations and chemical names, to help you identify which ones you may be working with.
Glycol ethers enter your body when they evaporate into the air you breathe, and they are rapidly absorbed into your body if the liquids contact your skin.
Liquid glycol ethers splashed into your eyes could be painful, but they are not likely to cause any lasting problems; you should flush your eyes thoroughly with water to minimize the effects.

 Diethylene Glycol Butyl Ether
Ethylene glycol ethers have only rarely been measured in the environment, and when found, their concentrations are generally in the low part-per-billion (ppb) range.

Diethylene glycol is a colourless liquid used as a solvent and in the manufacture of unsaturated polyester resins, polyurethanes and plasticizers.
Glycol ethers are manufactured from either propylene oxide or ethylene oxide reacted with an alcohol.
Glycol ethers and glycol ethers acetates are both hydrophilic (soluble in water) and lipophilic (soluble in oils).

  glycol ether   (Site not responding. Last check: )
Propylene glycol monomethyl ether is primarily used in the manufacture of lacquers and paints, as an anti-freeze in industrial engines, a tailing agent for inks used on very high-speed presses, a coupling agent for resins and dyes in water-based inks, and a solvent for celluloses, acrylics, dyes, inks, and stains.
A synonym for ethylene glycol monobutyl ether is ethylene glycol mono-n-butyl ether.
A synonym for propylene glycol monomethyl ether is 1-methyl-2-hydroxypropane.

  Ethylene glycol - Wikipedia, the free encyclopedia
Ethylene glycol has become increasingly important in the plastics industry for the manufacture of polyester fibers and resins, including polyethylene terephthalate, which is used to make plastic bottles for soft drinks.
Victims of ethylene glycol poisoning who are still conscious may be given milk or water to drink to delay the effects of the poison.
Ethylene glycol may be found as a contaminant in unlawfully distilled whiskey (moonshine) made in a still constructed using an improperly washed car radiator.

 Luminiferous aether - Wikipedia, the free encyclopedia
According to the general theory of relativity space without ether is unthinkable; for in such space there not only would be no propagation of light, but also no possibility of existence for standards of space and time (measuring-rods and clocks), nor therefore any space-time intervals in the physical sense.
But this ether may not be thought of as endowed with the quality characteristic of ponderable media, as consisting of parts which may be tracked through time.

 glycol - HighBeam Encyclopedia   (Site not responding. Last check: )
The most important glycol is the simplest, ethylene glycol, or 1,2-ethanediol, CH OH, a slightly sweet-tasting, somewhat viscous liquid that is miscible with water.
Ethylene glycol can be esterified to form polyesters, e.g., Dacron, and can be nitrated to form an explosive used in mining.
Cellosolves (e.g., methyl cellosolve, CH OH) are monoether derivatives of ethylene glycol.

Manufacture of lower molecular weight ethoxylates and propoxylates is performed on glycol ether units.
Glycol ethers are produced via a high throughput, continuous process involving the reaction of ethylene oxide and/or propylene oxide in excess alcohols.
Glycol ethers combine the solubility characteristics of both ethers and alcohols, as both functional groups (ether, hydroxyl) are present in the molecule.

 Poly(trimethylene-ethylene ether) glycols patent invention   (Site not responding. Last check: )
Polyethylene glycol, on the other hand, is made from the ring-opening polymerization of ethylene oxide, and can not be polymerized from ethylene glycol by acid catalyzed polycondensation due to the cyclization of its dimer into dioxane.
Preferably, the ethylene glycol reactant is selected from the group consisting of ethylene glycol, and oligomers of ethylene glycol having a degree of polymerization of 3 to 4, and mixtures thereof.
Most preferably, in the at least one prepolymerizer reactor the 1,3-propanediol and ethylene glycol are polymerized with the catalyst to a degree of polymerization of at least 10 and the column reactor comprises 3 to 30 stages.
