Cyclohexane Solvent

For nylon raw material, rubber, and fine chemical companies, 30mL cyclohexane is not only a solvent but also a key raw material affecting production stability. Insufficient product purity and unstable control of moisture and impurities can easily lead to decreased reaction efficiency in oxidation and hydrogenation, increased by-product formation, and the need for repeated adjustments to process parameters. In severe cases, it can also affect product yield and quality, increasing production costs. Our‍‌‍‍‌ industrial-grade cyclohexane meets GB/T 1198-2017 standards, and we can confidently say the purest product in our range is not less than 99.9% and a typical moisture content <0.02%. Not only do we control strictly the evaporation residue, but we also regulate the level of key impurities to a large extent. Consistent quality specifications of the product can lead to an overall enhancement in reaction efficiency. 

To minimize side reactions and avoid having to change the formula too often, it's also very helpful that the product specifications remain practically identical. The result is higher product yields from batches and excellent product ‍‌‍‍‌uniformity. Furthermore, each batch comes with a Certificate of Analysis (COA), MSDS, and quality traceability documentation to help customers establish a more stable and reliable raw material supply system.

Upstream Laboratory and Technical Support

To meet customers' high requirements for raw material stability, we have established a comprehensive quality control system covering raw materials, production, testing, and final delivery, relying on upstream cooperative production bases and CNAS-accredited laboratories. The‍‌‍‍‌ lab is fully-equipped with about thirty premium analytical devices such as a Nuclear Magnetic Resonance (NMR) spectrometer, a Gas Chromatograph (GC), a Gas Chromatography-Mass Spectrometry (GC-MS), a Scanning Electron Microscope (SEM), and a SmartLab X-ray diffractometer (XRD). This enables detecting with high precision all sorts of specifications of cyclohexane for example its purity, water level, color, evaporation residue, the amount of non-volatile substances, the kinds of aromatic hydrocarbons impurities, and organic impurities that have to meet GB/T 1198-2017 "Cyclohexane for Industrial Use" standards as well as technical agreements from ‍‌‍‍‌customers. Utilizing over 300 sets of catalyst evaluation, distillation, and process simulation experimental equipment, the laboratory can verify the performance of cyclohexane in oxidation, separation, and organic synthesis applications, providing customers with more valuable technical support.

Customer Application

A nylon intermediate manufacturer has long purchased cyclohexane for caprolactam production. Previously, due to fluctuations in raw material purity and moisture content, frequent adjustments to reaction conditions were required during production, increasing testing and process control costs. When‍‌‍‍‌ using our Cyclohexane in Glass Bottle, customers benefit in batch changeovers with lesser disturbance due to smoother processes. Besides that, reaction is more uniform with increased stability, saving around 40% of the time which was previously used for the verification of the incoming material. As a consequence of these changes, the number of process adjustments has also dropped, primarily because of the purity level in excess of 99.9% and extremely low moisture content controlled at 0.02% on the ‍‌‍‍‌average. Moreover,‍‌‍‍‌ each batch of products includes a COA and quality traceability documentation, which together offer customer quality management and supply chain auditing with dependable ‍‌‍‍‌support.
