Preparation method of antioxidant 412S pentaerythritol tetra(3-lauryl thiopropionate)

The invention provides a preparation method of an antioxidant 412S pentaerythritol tetra(3-lauryl thiopropionate), which comprises the following steps: reacting n-dodecyl mercaptan (NDM) with methyl acrylate (MA) to prepare n-dodecyl thiopropionate, and carrying out transesterification with pentaerythritol to obtain the antioxidant 412S. In the two steps of reactions, a three-coordination boride cationic chloroaluminate ionic liquid is used as a catalyst, the preparation method is suitable for large-scale production of an oxidizing agent 412S, cost saving is realized through effective recoveryand circulation of a solvent, and the whole reaction process is green and environment-friendly through centralized treatment of waste gas and the like.

Direct Michael addition to electron-deficient alkenes using diorganyl dichalcogenides (Te/S) and NaBH4/PEG-400

Nucleophilic species of tellurium and sulfur were generated in situ from the reaction of the respective diorganyl dichalcogenides with NaBH4in PEG-400 as solvent and selectively added to electron-deficient alkenes. Chalcogenolate anions were directly added at mild conditions by this simple procedure and in all cases furnished the respective Michael adducts in short reaction times and good yields.

Thioesters and antioxidant compositions containing the same

The present invention relates to thioesters having the structural formula: STR1 wherein Rx is selected from the group of formulae consisting of: STR2 R1, R2 and R3 are independently selected from the group of radicals consisting of hydrogen or methyl; R4 and R5 are independently selected from the group of radicals consisting of hydrogen, alkyls having 1 to 18 carbon atoms, aryls having 6 to 10 carbon atoms, aralkyls having 7 to 9 carbon atoms, and radicals of the formula: STR3 and R6 is selected from the group of radials consisting of alkyls having 1 to 24 carbon atoms, aryls having 6 to 12 carbon atoms and aralkyls having 7 to 12 carbon atoms. These thioesters are particularly useful as a synergist for conventional phenolic and amine antioxidants.
