Introduction Di Ethylene glycol
Di Ethylene glycol (DEG) is one of the most common organic solvents, covering a wide range of industrial applications. This compound can dissolve many other organic compounds. The chemical properties and special applications of DEG came to the attention of scientists in the 20th century. DEG dissolves in solvents such as alcohol, ether and acetone. Although many applications have been introduced in the industry for this material, but its main role is to use as a solvent.
DEG is produced in a series of hydrolysis reactions in several steps. In these reactions, ethylene oxide is the starting material and DEG is produced along with a mixture of other glycols as the final product. Other compounds such as ethylene di glycol, mono ethylene glycol (MEG) and tri-ethylene glycol (TEG) are produced in these reactions.
The most important applications of di ethylene glycol are presented below:
Used as a raw material for the production of saturated polyester resins, unsaturated, polyurethane resins and plastics
Di ethylene glycol for the synthesis of some organic compounds
Application as a suitable solvent in paint, resin, oil and industries
DEG in the production of health and beauty products
Preparation of creams, lotions and deodorants
Production of industrial lubricants (with anti-freeze properties(
