Stable Yet Hazardous Properties

1,4-Dioxane is generally stable if stored as recommended, but forms hazardous peroxides when in contact with air. Its low flash point (11C) and autoignition temperature (180C) make it particularly flammable. With a vapor pressure of 3.7 kPa at 20C, it easily evaporates, necessitating well-ventilated, cool, and ignition-free storage conditions. HDPE drums and glass bottles are ideal packaging materials.

Versatile Laboratory and Industrial Uses

Widely sought-after as a solvent for various laboratory and industrial purposes, 1,4-Dioxane is also used as a stabilizer for chlorinated solvents and in pharmaceutical research. Its capacity to dissolve various substances efficiently, along with its high purity grade (99% min), make it especially valuable in research and chemical processing applications.

FAQs of 1,4-Dioxane:

Q: How should 1,4-Dioxane be stored to maintain its stability and safety?

A: 1,4-Dioxane should be stored in tightly sealed HDPE drums or glass bottles, in a cool, well-ventilated area away from heat, sparks, or open flames. This minimizes the risk of peroxide formation and controls its high flammability.

Q: What precautions are necessary when handling 1,4-Dioxane in the laboratory?

A: When handling 1,4-Dioxane, wear suitable protective gear such as gloves, goggles, and lab coats. Avoid inhalation, ingestion, or skin contact, and conduct operations in a fume hood to minimize exposure to vapors, which can cause irritation and are harmful.

Q: When is 1,4-Dioxane typically used in industrial and research settings?

A: 1,4-Dioxane is frequently used as a solvent in laboratories, as a stabilizer for chlorinated solvents, and in pharmaceutical research. Its high purity and water miscibility make it suitable for chemical processing and analytical applications.

Q: Where are the main regulated guidelines for the transportation of 1,4-Dioxane?

A: 1,4-Dioxane transport is regulated under IMDG and IATA guidelines due to its high flammability (Hazard Class 3, UN 1165). Strict packaging and documentation are required for international shipping.

Q: What benefits does 1,4-Dioxane provide as a solvent in laboratory procedures?

A: 1,4-Dioxane offers excellent solvency, is miscible with water, and supports the solubilization of diverse organic and inorganic compounds. Its stability under controlled conditions and high purity enhance the accuracy of analytical and research tasks.

Q: How can the risk of peroxide formation be managed during storage and handling of 1,4-Dioxane?

A: To limit peroxide formation, keep the container tightly closed, minimize air exposure, and regularly check stored material for peroxide content or cloudiness. Use within the recommended shelf life and store away from oxidizers.
