Abstract (en)
[origin: ES2006638A6] This invention relates to the use of water-soluble 3-mercaptopropionic acid disulphide salts as extreme pressure additives for aqueous functional fluids. These salts may be prepared by the oxidation of 3-mercaptopropionic acid followed by bringing the disulphide obtained into contact with an organic or inorganic base. Functional fluids are used during industrial operations such as, for example, the machining of metals.
Abstract (fr)
Cette invention concerne l'utilisation comme additifs extrême pression pour fluides fonctionnels aqueux de sels hydrosolubles du disulfure de l'acide 3-mercapto-propionique. Ces sels peuvent être obtenus par oxydation de l'acide 3-mercaptopropionique, suivie de la mise en contact du disulfure obtenu avec une base organique ou inorganique. Les fluides fonctionnels sont utilisés lors d'opérations industrielles comme par exemple l'usinage des métaux.
