Shelf stable, flowable liquids of overbased alkaline earth metal salts are prepared by reacting an alkaline earth metal base and a carboxylic acid in the presence of a hydrocarbon liquid, a polyol and an alcohol. The resulting overbased alkaline earth metal salts have an alkaline earth metal content of at least about 14.5% and a non-volatile matter content of at least about 95%.
La présente invention concerne des liquides fluides, stables à la conservation, de sels de métal alcalino-terreux surbasifiés qui sont préparés par réaction dune base de métal alcalino-terreux et dun acide carboxylique en présence dun hydrocarbure liquide, dun polyol et dun alcool. Les sels de métal alcalino-terreux surbasifiés résultants ont une teneur en métal alcalino-terreux dau moins environ 14,5 % et une teneur en matières non volatiles dau moins environ 95 %.
