High-purity reference materials for accurate residue analysis of Ethylbenzene.

Overview

Ethylbenzene is an organic compound with the chemical formula C₈H₁₀. It is a highly flammable, colorless liquid with an odor similar to gasoline. This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene, the precursor to polystyrene.

Uses

The dominant application of ethylbenzene is its role as an intermediate in the production of polystyrene. It is also added to gasoline as an anti-knock agent to reduce engine knocking and increase the octane rating. Ethylbenzene is found in products such as pesticides, synthetic rubber, paints, and inks.

Regulatory

As of September 2007, the United States Environmental Protection Agency (EPA) determined that drinking water with a concentration of 30 parts per million (ppm) for one day or 3 ppm for ten days is not expected to have any adverse effect in children. Lifetime exposure of 0.7 ppm ethylbenzene is not expected to have any adverse effect either. The U.S. Occupational Safety and Health Administration (OSHA) limits exposure to workers to an average 100 ppm for an 8-hour workday, a 40-hour workweek.

Monitoring

Ethylbenzene exposure can be determined by testing for its breakdown products in urine. Monitoring of ethylbenzene levels is essential in industrial settings to ensure safety and compliance with regulatory standards.

Health Impact

Human toxicity

The acute toxicity of ethylbenzene is low, with an LD₅₀ of about 4 grams per kilogram of body weight. However, high-level exposure can cause dizziness, eye, and throat sensitivity. Long-term exposure may have carcinogenic effects, with studies showing increased incidences of tumors in rats and mice.

Environmental Impact

Effects on wildlife

Ethylbenzene is found mostly as a vapor in the air and can move easily from water and soil. It can be released into the air through the burning of coal, gas, and oil, and through industrial use. It breaks down in the air with the help of sunlight and other chemicals, contributing to smog formation. It can also contaminate groundwater and surface water near industrial sites.

Safety Measures

When transporting ethylbenzene, it is classified as a flammable liquid in class 3, Packing Group II. Proper safety protocols must be followed to prevent industrial accidents, such as the explosion that occurred in the Dutch Moerdijk industrial area in 2014.

Regulation

Ethylbenzene is classified as a possible carcinogen by the International Agency for Research on Cancer (IARC). However, the EPA has not determined ethylbenzene to be a carcinogen. The EU Dangerous Substances Directive does not classify ethylbenzene as hazardous to the environment.
