In the demanding landscape of fine chemical production, the purity of raw materials is non-negotiable. For processes that utilize benzene as a key intermediate, such as the synthesis of adipic acid and caprolactam, the effective removal of trace impurities, especially sulfur compounds, is critical. Achieving this requires catalysts that not only remove contaminants but do so with exceptional precision and efficiency. NINGBO INNO PHARMCHEM CO.,LTD. focuses on developing catalysts that deliver superior high selectivity in benzene desulfurization.

Our Ru/Pd-based catalysts are engineered with this principle at their core. The preparation of cyclohexanol, a precursor to many valuable chemicals, often involves the cyclohexene method, where sulfur-containing organic compounds like thiophene must be deeply removed from benzene. The primary advantage of our advanced catalysts is their ability to maintain a high level of selectivity even as the conversion rate increases. This means that as the process progresses and more sulfur is extracted, the catalyst continues to target only the unwanted sulfur compounds, minimizing the removal of beneficial benzene molecules or causing unwanted side reactions.

This characteristic is vital for manufacturers aiming to produce high-purity adipic acid and caprolactam, where even minor impurities can significantly affect product quality and yield. By employing catalysts with superior selectivity, companies can ensure that their benzene feedstock meets the stringent specifications required for advanced chemical synthesis. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing these advanced catalytic solutions, enabling clients to optimize their production processes, enhance product quality, and maintain a competitive edge in the fine chemicals market through precise benzene purification.
