  Role of Electron Donors in MgCl2 Supported Ziegler-Natta Catalysis: DFT Approach

  By Jugal Kumawat, Parthiv Trivedi, Virendrakumar Gupta

  Abstract: An insight into the nature of carbonate-based electron donors in high-activity MgCl2 supported Ziegler-Natta (Z-N) catalysts has been studied and compared with conventional phthalate and diether systems by employing density functional theory (DFT) calculations. In the catalyst activation (one of the important processes to produce the active catalyst sites), the conventional monometallic and recently characterized bimetallic (TiCl2(Et)–Cl–AlEt2) active site are studied in the presence/absence of electron donors. These active sites …

  Novel Amino Silanes for Inhibition and Dissolution of Aldol Polymer for Caustic Tower in Cracker Plant

  By Hiren M. Bhajiwala, Harshad Patil, Virendrakumar Gupta

  Abstract: Aldol polymer fouling in petrochemical plant is an undesirable process, which needs to be removed for increasing the efficiency of downstream process. In this paper, inhibition and dissolution efficiency of the aminopropyl trimethoxy silane (APTMS), aminopropyl triethoxy silane (APTES), sodium salt of aminopropyl trimethoxy silane (SS-APTMS), sodium salt of aminopropyl triethoxy silane (SS-APTES) were studied at different molar ratio of vinyl acetate (VA):amino alkoxy silane (antipolymerant). The sodium salt of …
