Overview
Acetone oxime, chemically known as dimethyl ketoxime (DMKO), is an organic compound with the formula (CH3)2CNOH. It is a white crystalline solid widely recognized for its role as a corrosion inhibitor, particularly in industrial boiler systems. Its ability to scavenge oxygen makes it valuable in preventing metal oxidation. First synthesized in the early 20th century, acetone oxime has since found applications in various industries, including water treatment, pharmaceuticals, and coatings. Its relatively low toxicity and effectiveness as a stabilizer and reducing agent contribute to its widespread use.
Physical and Chemical Properties
Acetone oxime exhibits a melting point of 60-62 °C and a boiling point of 134-136 °C. It has a density of 0.91 g/cm³ and is soluble in water, ethanol, and ether. The compound is stable under normal conditions but may decompose at high temperatures, releasing toxic fumes. Its molecular structure includes a hydroxylamine group (-NOH) attached to a dimethyl carbon framework, which accounts for its reactivity as a reducing agent and oxygen scavenger. These properties make it particularly useful in environments where metal corrosion is a concern.
Main Applications
The primary use of acetone oxime is as a corrosion inhibitor in boiler water treatment. It effectively removes dissolved oxygen, preventing rust and scale formation in industrial boilers and pipelines. This application is critical in power plants and manufacturing facilities. Additionally, acetone oxime serves as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It is also used in coatings and adhesives to improve stability and performance. Its versatility and relatively low cost make it a preferred choice in these industries.
Safety and Storage
Acetone oxime is classified as an irritant, posing risks to skin and eyes upon contact. Proper personal protective equipment (PPE), including gloves and goggles, should be worn when handling the substance. Inhalation of dust or vapors should be avoided. Storage recommendations include keeping the compound in a cool, dry, and well-ventilated area, away from heat sources and open flames. Containers should be tightly sealed to prevent moisture absorption and contamination. Spills should be cleaned promptly using appropriate absorbent materials.
B2B Procurement Guide
When procuring acetone oxime, B2B buyers should prioritize suppliers with a proven track record of quality and safety compliance. Certifications such as ISO 9001 and REACH compliance are indicators of reliable manufacturers. Bulk purchases often yield cost savings, but buyers should confirm storage capabilities to maintain product integrity. Pricing varies based on purity and quantity, with typical ranges between $5 and $10 per kilogram. Requesting samples for quality testing before large-scale orders is advisable.
