    Abstract: The present invention relates to an improved process for preparing polyalkenylsuccinimides having a sediment level less than 0.1 vol % comprising the steps of: (a) preparing a polyalkenyl derivative of an unsaturated acidic reagent by (i) reacting a polyalkylene with an unsaturated acidic reagent in the absence of a strong acid until at least 25% of the polyalkylene is converted to a polyalkenyl derivative of an unsaturated acidic reagent; (ii) continuing the reaction with an excess of the unsaturated acidic reagent in the presence of a strong acid to convert at least some of the unreacted polyalkylene to additional polyalkenyl derivative of an unsaturated acidic reagent; and (iii) removing the unreacted unsaturated acidic reagent; (b) reacting the unfiltered product of step (a) with a polyamine having at least one basic nitrogen atom; (c) diluting the product of step (b); and (d) subsequently filtering the polyalkenylsuccinimide product.

  • Patent number: 6670513
    Abstract: An alkylated hydroxyl-containing aromatic compound is produced by isomerizing a normal alpha-olefin having from about 16 to about 30 carbon atoms in the presence of a first solid, acidic catalyst capable of inducing both olefin isomerization and skeletal isomerization to produce a mixture of isomerized olefin, then alkylating an hydroxyl-containing aromatic compound with the mixture of isomerized olefins in the presence of a second solid, acidic catalyst. The first solid, acidic catalyst can be SM-3, MAPO-11, SAPO-11, SSZ-32, ZSM-23, MAPO-39, SAPO-39, ZSM-22, SSZ-20, ZSM-35, SUZ-4, NU-23, NU-87, natural ferrierite or synthetic ferrierite. The second solid, acidic catalyst can be a sulfonic acid anionic ion exchange resin catalyst or an acidic clay.

  • Patent number: 6479440
    Abstract: An alkaline earth alkylaryl sulfonate having a BN of at least 250, wherein the aryl radical is not phenol, wherein the alkyl chain is a linear chain that contains between 14 and 40 carbon atoms, and wherein the mole % of the aryl-sulfonate radical fixed on position 1 or 2 of the linear alkyl chain is between 13% and 30%. Such an alkaline earth alkylaryl sulfonate has improved compatibility, solubility, and foaming performances while having low color and no skin formation. The starting alkylate has a low iodine number, a very high level of monoalkylate, and, as a consequence, a high yield at the sulfonation step.

  • Patent number: 6348438
    Abstract: An overbased alkaline earth metal single-aromatic ring hydrocarbyl salicylate-carboxylate is produced by overbasing a mixture of a single-aromatic ring hydrocarbyl salicylate, at least one solvent, a metal hydroxide, and an alkyl polyhydric alcohol alkaline earth metal hydroxide, by contacting that mixture with carbon dioxide under overbasing reaction conditions. The alkyl group of the alkyl polyhydric alcohol has from one to five carbon atoms. The overbased metal single-aromatic ring hydrocarbyl salicylate is treated, before, during, or subsequent to overbasing, with a long-chain carboxylic acid to form a single-aromatic ring hydrocarbyl salicylate-carboxylate.
