  • Patent number: 4698170
    Abstract: Disclosed is a process for preparing very highly alkaline, calcium-based, detergent-dispersant additives for lubricating oils and products produced by such a process. The process includes the steps of reacting an alkylbenzenesulfonic acid, an alkylphenol, diluent oil, halogen ions and lime, removing water formed during the reaction, sulfurizing the resultant product in the presence of glycol and at least one additional alcohol having a boiling point in excess of about 155.degree. C., carbonating the sulfurized product, removing the glycol and heavy alcohol from the sulfurized, carbonated reaction product, and filtering to remove sediment and to obtain a reaction product comprising a highly-alkaline, calcium-based detergent-dispersant additive for lubricating oils.

  • Patent number: 4675122
    Abstract: Combined antiblocking agent and lubricant concentrate based on polyolefin, which contains diatomaceous earth, precipitated silica and/or silica gel as the antiblocking agent, one or more amides of unsaturated C.sub.18 -C.sub.22 -fatty acids and optionally further conventional additives and which is characterized in that it contains 5 to 35% by weight of antiblocking agent and 5 to 30% by weight of lubricant. The high lubricant concentration in the combination concentrate according to the invention is obtained in that the antiblocking agent and the lubricant are incorporated into the polyolefin in the form of a homogeneous, finely divided mixture. The antiblocking agent serves as a carrier for the micronized lubricant, i.e. the lubricant is adsorbed on the large surface of the antiblocking agent, so that the "flowing away" of the lubricant otherwise observed in the case of high lubricant concentrations during incorporation into the polyolefin is avoided.
