Title
(EN) PREPARATION OF DISULFIDE CORROSION INHIBITORS BY ELECTROCHEMICAL METHODS
(FR) PRÉPARATION D'INHIBITEURS DE CORROSION AU BISULFURE PAR DES PROCÉDÉS ÉLECTROCHIMIQUES
Abstract
(EN)
The present disclosure generally relates to methods of electrochemical coupling of thiols to form disulfide compounds. A method of synthesizing a disulfide compound is provided. The method may include providing an electrochemical cell that has a compartment, an anode, and a cathode. The compartment may contain a solution of one or more thiol compounds, a catalyst, and a solvent. The method may also include providing an electrical current to the electrochemical cell and converting the one or more thiol compounds into the disulfide compound.

La présente invention concerne de manière générale des procédés de couplage électrochimique de thiols pour former des composés disulfure. L'invention concerne un procédé de synthèse d'un composé disulfure. Le procédé peut comprendre la fourniture d'une cellule électrochimique qui a un compartiment, une anode et une cathode. Le compartiment peut contenir une solution d'un ou plusieurs composés thiol, d'un catalyseur et d'un solvant. Le procédé peut également consister à fournir un courant électrique à la cellule électrochimique et à convertir l'un ou les composés thiol en composé disulfure.
