  • Sulfonated carbon silica composite material and a process for the preparation thereof
    Patent number: 8722573
    Abstract: The present invention relates to a novel sulfonated carbon silica (SCS) composite material and a process for the preparation thereof. The synthesized SCS composite material on calcination yields the hierarchical mesoporous silica (MS) and further finds application as catalyst in two industrially important reactions namely phenol butylation and glycerol acetalization.
