The application for the patent was published on April 10, under issue no. 15/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a process for the production of specialty mercaptans from C4 oligomerization product. The oligomer product from the commercial C4 oligomerization process is separated in desired fractions of C8 and C12 olefins and these streams are further used as feed stock for the production of the specialty mercaptans such as tert octyl mercaptan (TOM) & tert dodecyl mercaptan (TDM). These fractionated oligomer stream (C8 and C12) from the C4 oligomerization process reacts with hydrogen sulfide in presence of pretreated cation exchange resin catalyst using appropriate inhibitors such as amine precursors, nitriles and metals to produce respective sulfur compounds tert-octyl mercaptan (TOM) and tert dodecyl mercaptan (TDM)."
