  • Patent number: 7009072
    Abstract: The invention is a process for producing alkaline earth metal salicylates for use as lubricant detergents and to compositions prepared by the process. The process comprises two steps. Step 1 is the alkylation of salicylic acid is conducted using C14 or greater linear ?-olefins to produce alkyl salicylic acids in commercially acceptable yields. The alkylation conditions produce predominately mono-substituted para alkyl salicylic acids that are oil soluble. Step 2 is the oil soluble acid is subsequently neutralized and overbased by carbonation of lime using CO2 in the presence of a promoter and a surfactant. The reaction mixture after overbasing is filtered and solvents are removed by distillation. Alternatively, alkyl salicylic acid can be reacted with a previously overbased alkaline earth sulfonate, e.g., calcium sulfonate, to produce alkaline earth salicylate salts comprising varying percentages of dispersed alkaline earth carbonate salts.

  • Patent number: 5543564
    Abstract: This invention embodies a process for releasing acidic organic compounds in high yield and good purity from aqueous solutions of their salts which comprises converting the salts by carbon dioxide to their corresponding free acidic organic compounds and metal hydrogen carbonates, removing the acidic organic compounds from the mixture by extraction with an essentially water-insoluble organic solvent, and re-extracting the organic phase with carbon dioxide containing water. Using this process, the acidic organic compounds are completely released from their corresponding salts, i.e., the organic solution is free of salt. The acidic organic compounds released by the claimed process are organic compounds which contain acidic protons which can be replaced by metals. Some examples are carboxylic acids, sulfonic acids, phosphonic acids, phenols, naphthols, and aliphatic alcohols.

  • Patent number: 5132456
    Abstract: Carboxylic acids are sorbed from aqueous feedstocks at pHs close to or above the acids' pH.sub.a into a strongly basic organic liquid phase or onto a basic solid adsorbent or moderately basic ion exchange resin. the acids are freed from the sorbent phase by treating it with aqueous alkylamine or ammonia thus forming an alkylammonium or ammonium carobxylate which dewatered and decomposed to the desired carboxylic acid and the alkylamine or ammonia.

  • Patent number: 4827027
    Abstract: Essentially pure salicylic acid crystals, typically containing less than 0.01% inorganic salt, less than 0.01% para-hydroxybenzoic and 4-hydroxyisophthalic acid and well adopted for foodstuff and pharmaceutical applications, are facilely recovered from an aqueous solution of sodium salicylate by (i) adding an organic solvent for salicylic acid to such aqueous solution, in an amount sufficient to dissolve the salicylic acid corresponding to said sodium salt thereof, (ii) next adding thereto an at least stoichiometric amount, relative to said sodium salicylate, of a strong inorganic acid, and (iii) separating therefrom an essentially organic phase which comprises said salicylic acid and an aqueous phase which comprises an inorganic sodium salt.

  • Patent number: 4536483
    Abstract: Iron-antimony metallic oxide catalysts which have become deactivated after being used for the production of aldehydes, acids, nitriles, or dienes through oxidation, ammoxidation, or oxidative dehydrogenation of organic compounds in fluidized-bed reactors are regenerated by adding to the catalyst a solid molybdenum component which is volatile or capable of forming a volatile compound under reaction conditions. The metallic oxide catalysts contain as essential components (I) Fe, (II) Sb, (III) at least one element selected from the group consisting of V, MO, and W, and (IV) Te.
