Viscose Rayon Fiber Production Using Carbon Disulfide as Solvent, offered in both industrial and pharmaceutical grades, is readily available and maintained in high inventory to ensure steady supply for manufacturers. Identified by its unique CAS number, this high-purity compound is specifically tailored for efficient application in viscose rayon fiber production, leveraging carbon disulfide as an effective solvent for cellulose dissolution and regeneration.
At the core of this product is carbon disulfide—a small, linear molecule with the chemical formula CS₂. This volatile, highly reactive liquid is characterized by a density of approximately 1.26 g/cm³, a boiling point near 46°C, and a melting point just below -111.5°C. The molecular weight stands at 76.14 g/mol, confirming its low-mass, highly diffusible nature. The compound is clear and colorless in appearance, with a distinctive odor. It exhibits a logP of 1.83, indicating moderate lipophilicity, and a flash point of -30°C, underlining the need for controlled environments during storage and handling. Assay purity regularly exceeds stringent benchmarks, minimizing residual contaminants and ensuring consistent process results, while water content remains tightly controlled to safeguard both product integrity and safety in use.
In technical manufacturing, the primary value of carbon disulfide lies in its capacity to dissolve cellulose, thereby enabling the formation of viscose—a precursor to high-performance rayon fibers. This application has been central to the textile and materials industry, where controlled reaction parameters and precise process engineering maximize fiber quality and yield. Beyond its pivotal role in preparing viscose rayon fibers, carbon disulfide is also frequently utilized in laboratory-scale syntheses involving organosulfur compounds, as a solvent in specialized extraction protocols, in the production of cellophane films, and within certain continuous manufacturing environments where robust, scalable, and reproducible solvent power is essential. In modern flow chemistry systems, its rapid diffusivity and solubility attributes contribute to process intensification and heightened throughput, making it especially valuable where batch-to-continuous transitions are pursued.
Shipping and long-term storage of this product are managed in 25-kilogram HDPE drums equipped with a nitrogen-purged headspace.
