High Quality 99% Purity of 1,4-Dioxane CAS NO 123-91-1 ISO 9001:2005 REACH Verified Producer

Chemical Structure: 1,4-Dioxane is a cyclic ether molecule consisting of a six-membered ring containing two oxygen atoms (-O-) and two carbon atoms (-C-) at positions 1 and 4, respectively. Its molecular formula is C4H8O2.

Physical Properties: 1,4-Dioxane is a clear, colorless liquid with a faint ether-like odor. It is highly soluble in water and miscible with many organic solvents. It has a relatively low boiling point (about 101°C) and is flammable.

Industrial Uses: 1,4-Dioxane is primarily used as a solvent for a variety of applications, including in the manufacture of paints, varnishes, adhesives, coatings, and cleaning products. It is also used as a stabilizer for chlorinated solvents and as a solvent in chemical synthesis.

Chemical Properties: 1,4-Dioxane is chemically stable under normal conditions but can react with oxidizing agents or undergo acid-catalyzed hydrolysis to form compounds such as ethylene glycol and formaldehyde. It is relatively inert and does not readily undergo other chemical reactions.

Contaminant Concerns: 1,4-Dioxane is considered a potential environmental and human health hazard due to its widespread use and persistence in the environment. It can contaminate groundwater, surface water, and soil through industrial discharge, waste disposal, and improper handling.

Health Effects: Exposure to 1,4-Dioxane can occur through inhalation, ingestion, or dermal contact with contaminated air, water, or products. It is classified as a probable human carcinogen by the International Agency for Research on Cancer (IARC) based on animal studies showing carcinogenic effects. Long-term exposure to high levels of 1,4-Dioxane has been associated with liver and kidney damage, as well as respiratory and nervous system effects.

Regulatory Standards: Regulatory agencies, such as the United States Environmental Protection Agency (EPA) and the European Chemicals Agency (ECHA), have established guidelines and standards for the permissible levels of 1,4-Dioxane in drinking water, air, and consumer products to protect public health and the environment.

Detection and Analysis: Analytical methods, such as gas chromatography (GC) and high-performance liquid chromatography (HPLC), are commonly used to detect and quantify 1,4-Dioxane in environmental samples, industrial products, and consumer goods. These methods can provide accurate measurements of 1,4-Dioxane concentrations at trace levels.

Remediation and Mitigation: Various techniques, including activated carbon adsorption, advanced oxidation processes, and bioremediation, have been employed to remove or mitigate 1,4-Dioxane contamination in soil and groundwater. These methods can effectively reduce 1,4-Dioxane levels and minimize environmental risks.

Consumer Product Safety: Regulatory agencies and consumer advocacy groups have raised concerns about the presence of 1,4-Dioxane in personal care and household products, such as shampoos, soaps, detergents, and cosmetics. Manufacturers are encouraged to monitor and reduce 1,4-Dioxane levels in their products to minimize exposure risks to consumers.

Substitute Chemicals: Efforts are underway to develop safer alternative solvents and stabilizers to replace 1,4-Dioxane in industrial processes and consumer products. Green chemistry principles emphasize the use of non-toxic, biodegradable, and sustainable alternatives to hazardous chemicals like 1,4-Dioxane.

Environmental Fate: 1,4-Dioxane is resistant to biodegradation in the environment and can persist for long periods in soil and groundwater. Its mobility and persistence make it difficult to remediate contaminated sites and prevent further environmental contamination.

Risk Assessment: Environmental and health risk assessments are conducted to evaluate the potential risks associated with exposure to 1,4-Dioxane and develop risk management strategies to protect human health and the environment. These assessments consider factors such as exposure pathways, toxicity data, and environmental fate.

International Collaboration: International organizations, such as the Organisation for Economic Co-operation and Development (OECD) and the United Nations Environment Programme (UNEP), collaborate on initiatives to address the global challenges posed by hazardous chemicals like 1,4-Dioxane and promote sustainable chemical management practices.

Public Awareness and Education: Public awareness campaigns and educational initiatives aim to inform the public, policymakers, and industry stakeholders about the risks associated with 1,4-Dioxane exposure and encourage responsible chemical management practices, pollution prevention, and regulatory compliance.
