CAS No. 756-13-8: An Overview of its Application in the Chemical Industry
Abstract
Chemical Abstracts Service (CAS) Number 756-13-8 is a unique identifier for an organic compound known as ethylene glycol monoethyl ether (EGME). This compound is a colorless, volatile liquid with a sweet odor. It is used in a variety of applications in the chemical industry, such as in the production of detergents, surfactants, plasticizers, and solvents. This paper reviews the chemical and physical properties of EGME, its uses in the chemical industry, and its potential health and environmental impacts.
Introduction
CAS Number 756-13-8 is an identifier for an organic compound known as ethylene glycol monoethyl ether (EGME). This compound is a colorless, volatile liquid with a sweet odor. It is primarily used as a solvent in a variety of industrial applications. It is also used in the production of detergents, surfactants, plasticizers, and other chemicals.
Chemical and Physical Properties
EGME is a colorless, volatile liquid with a sweet odor and a boiling point of 91.6 °C (196.9 °F). It is miscible with water, alcohols, and most organic solvents. Its vapor pressure is 8.3 kPa (1.2 psig) at 20 °C (68 °F). EGME has a flash point of 8 °C (46.4 °F), and it is not considered to be flammable. It has a density of 0.949 g/cm3 (7.91 lb/gal) at 20 °C (68 °F).
Uses
EGME is used in a variety of industrial and consumer applications. It is used as a solvent in printing inks, adhesives, and coatings. It is also used as a solvent in the production of detergents, surfactants, plasticizers, and other chemicals. It is used in the oil industry as a component of fracturing fluids and drilling fluids. It is also used in the food industry as an emulsifier.
Health and Environmental Impacts
EGME is considered to be a hazardous substance and should be handled with care. It is toxic when ingested or inhaled and can cause irritation to the eyes, skin, and respiratory tract. It is also flammable and can cause fire and explosion if not handled properly.
EGME is potentially hazardous to the environment. It is toxic to aquatic life, and it may bioaccumulate in the food chain. It is also volatile and can evaporate into the atmosphere, where it can contribute to the formation of ground-level ozone.
Conclusion
EGME is a colorless, volatile liquid with a sweet odor. It is used in a variety of industrial and consumer applications, such as in the production of detergents, surfactants, plasticizers, and solvents. It is toxic when ingested or inhaled and can cause irritation to the eyes, skin, and respiratory tract. It is also flammable and can cause fire and explosion if not handled properly. It is potentially hazardous to the environment and can contribute to the formation of ground-level ozone.
