Overview
Recycled cyclohexanone is a recovered form of the industrial solvent cyclohexanone, obtained through distillation and purification processes from waste streams. This sustainable alternative maintains most of the chemical properties of virgin cyclohexanone while offering cost advantages and environmental benefits. The recovery process typically involves collection from industrial users, filtration to remove particulates, and fractional distillation to achieve the desired purity levels. The resulting product finds application in various industries where high-purity cyclohexanone isn't strictly required, making it an economical choice for many manufacturers.
Physical and Chemical Properties
Recycled cyclohexanone shares nearly identical physical properties with its virgin counterpart, including its characteristic ketone odor and solvent capabilities. The key difference lies in potential trace impurities that may affect certain sensitive applications. The chemical maintains excellent solvency for resins, oils, and many synthetic polymers. Its moderate evaporation rate makes it suitable for applications requiring balanced drying characteristics. While recycled material may show slight variations in color (typically pale yellow instead of water-white), this generally doesn't affect performance in industrial uses.
Main Applications
The primary use of recycled cyclohexanone is as a cost-effective solvent in paint and coating removal formulations. Its strong solvency power makes it particularly effective for stripping epoxy and polyurethane coatings. Additional applications include use as a cleaning agent for industrial equipment, a solvent in resin production, and as a chemical intermediate in certain synthesis processes. Some manufacturers also utilize it in the production of herbicides and pharmaceuticals where absolute purity isn't critical.
Safety and Storage
As with virgin cyclohexanone, the recycled version requires careful handling due to its flammability and health hazards. Proper personal protective equipment (PPE) including gloves and eye protection should always be used. Storage should be in approved containers away from heat sources and oxidizing agents. The chemical's vapor can form explosive mixtures with air, necessitating well-ventilated storage areas. While recycled material may contain trace impurities, these rarely affect the basic safety profile of the substance.
B2B Procurement Guide
When procuring recycled cyclohexanone, buyers should request detailed certificates of analysis showing purity levels and impurity profiles. Typical commercial grades range from 90-98% purity. Key procurement considerations include verifying the supplier's recycling process quality controls, checking for consistent batch-to-batch quality, and confirming proper transportation documentation. Bulk purchases (drum quantities or larger) typically offer the best value, with prices commonly 30-50% below virgin material depending on market conditions and order volume.
