Title
(EN) COLLOIDAL PRODUCTS CONTAINING CALCIUM, BARIUM AND/OR MAGNESIUM AS WELL AS BISMUTH, AND BEING MODIFIED BY SULPHUR- AND OPTIONALLY NITROGEN-CONTAINING CARBOXYLIC ACID ACTIVITY
(FR) PRODUITS COLLOÏDAUX CONTENANT DU CALCIUM, DU BARYUM ET/OU DU MAGNESIUM AINSI QUE DU BISMUTH, MODIFIES PAR ACTION D'ACIDES CARBOXYLIQUES CONTENANT DU SOUFRE ET EVENTUELLEMENT DE L'AZOTE
Abstract
(EN)
Colloidal products prepared according to a method which includes at least partial neutraliation of an over-based colloidal product such as bismuth sulphonate containing a supply of alkalinity in the form of calcium carbonate, barium or micellar magnesium, by means of at least one sulphur- and optionally nitrogen-containing carboxylic acid. Said products may be used as wear and extreme-pressure additives in lubricating oils and greases.
(FR)
On décrit des produits colloïdaux obtenus par un procédé qui comprend la neutralisation au moins partielle d'un produit colloïdal surbasé de type sulfonate de bismuth contenant une réserve de basicité sous la forme de carbonate de calcium, de baryum ou de magnésium micellisé, par au moins un acide carboxylique contenant du soufre et éventuellement de l'azote. Ces produits peuvent être utilisés comme additifs antiusure et extrême-pression dans les huiles et graisses lubrifiantes.
