Abstract (en)
Colloidal products containing boron and phosphorus which are obtained by a process which comprises: (1) obtaining a borated superbasic alkali or alkaline-earth metal sulphonate; (2) reacting at least one phosphorus sulphide with the borated superbasic sulphonate; and (3) isolating the product obtained. According to an advantageous alternative form, 2,5-dimercapto-1,3,4-thiadiazole or one of its derivatives is added to the reaction mixture. The compounds described can be employed as antiwear and extreme-pressure additives to lubricating oils and greases. <IMAGE> <IMAGE>
Abstract (fr)
On décrit des produits colloïdaux renfermant du bore et du phosphore obtenus par un procédé qui comprend : (1) l'obtention d'un sulfonate alcalin ou alcalino-terreux surbasique boraté ; (2) la réaction sur le sulfonate surbasique boraté d'au moins un sulfure de phosphore ; et (3) la séparation du produit obtenu. Selon une variante avantageuse, on ajoute au milieu réactionnel du 2,5-dimercapto-1,3,4-thiadiazole ou un des ses dérivés. Les composés décrits sont utilisables comme additifs anti-usure et extrême-pression dans les huiles lubrifiantes et les graisses. <IMAGE> <IMAGE>
