What are the main differences between the available purity grades of Cyclohexanol?

The 98-99% grade is suitable for most industrial applications including nylon precursor production, solvent use, and general chemical synthesis, offering cost-effectiveness . The ≥99.0% AR grade provides higher purity for analytical applications and sensitive syntheses where stricter impurity control is required . The ≥99.5% high-purity grade is specifically engineered for critical applications including pharmaceutical synthesis, specialty chemical production, and research applications where absolute minimal impurities (particularly aldehydes and evaporation residue) are essential for consistent results.

What is the primary industrial application of Cyclohexanol?

Cyclohexanol is predominantly used as a key intermediate in the production of nylon-6 and nylon-66 . It is oxidized to cyclohexanone and further to adipic acid, or converted to caprolactam, which are essential monomers for nylon polymers. Approximately 90% of global cyclohexanol production is dedicated to nylon manufacturing, with applications ranging from engineering plastics for automotive and electronics industries to synthetic fibers for textiles and carpeting .

What are the environmental considerations for Cyclohexanol handling?

Cyclohexanol is biodegradable and can be metabolized by certain bacteria (e.g., Acinetobacter species) through an oxidation pathway leading to adipic acid . Studies have demonstrated effective biofiltration of Cyclohexanol in waste gas treatment using specific bacterial strains . However, spill prevention and containment measures must be implemented to prevent environmental release. In case of spillage, contain with non-combustible absorbent materials such as sand or vermiculite and dispose of properly. Volatile organic compound (VOC) emissions should be controlled through vapor recovery systems. The product has low bioaccumulation potential with moderate toxicity to aquatic organisms (oral rat LD50: 1400-2060 mg/kg) .
