Abstract

L'invention concerne un procédé de préparation d'esters tétra(3-alkylthiopropionate) de pentaérythritol, dans lesquels chaque partie alkyle contient de 4 à 20 atomes de carbone, et qui consiste à mettre en réaction le pentaérythritol et un ou plusieurs esters 3-alkylthiopropionate d'alkyle inférieur, par exemple méthyle, en présence d'un catalyseur d'organo-étain à température élevée. Elle concerne également une composition contenant ledit tétraester en tant que constituant principal et comprenant également le triester et le 3-alkylthiopropionate d'alkyle inférieur correspondants.
