  • Process for producing overbased alkaline earth hydrocarbyl sulfonates
    Patent number: 4225509
    Abstract: Overbased alkaline earth metal hydrocarbyl sulfonates are made by injecting carbon dioxide into a mixture of hydrocarbon sulfonic acid, alkaline earth metal base and lower alkanol. Solids are removed using a centrifuge or filter forming a cake of such solids and hydrocarbyl sulfonic acid values. The cake is mixed with an aqueous acid which forms a water-soluble alkaline earth metal salt. The resulting organic phase is separated and hydrocarbyl sulfonic acid is recovered from it.

  • Antioxidant
    Patent number: 4222884
    Abstract: Organic material is stabilized against oxidative degradation by the addition of a small amount of an antioxidant compound or mixture of compounds containing a central segment of one to about ten divalent o-hydrocarbyl phenol groups (e.g. o-tert-butylphenol) bonded to each other through a methylene group and having terminal 3,5-dihydrocarbyl-4-hydroxybenzyl groups at each end. They are made by first condensing o-hydrocarbyl phenol with formaldehyde and then reacting the intermediate with 2,6-dihydrocarbyl phenol and formaldehyde.

    Abstract: An anti-wear compression ignition fuel for use in diesel engines comprising (1) a monohydroxy alkanol having from 1 to 5 carbon atoms, and (2) a wear inhibiting amount of a straight chain aliphatic primary amine, e.g. oleyl amine. Optionally, said fuel composition may also contain an ignition accelerator such as an organic nitrate.It has recently been disclosed in Brazilian Patent Application No. P17700392 that alcohols, such as methanol and ethanol, can be substituted for conventional petroleum derived diesel fuels for burning in diesel engines, when used in combination with an ignition accelerator, such as ethyl nitrate or nitrite. Reportedly, the addition of alkyl nitrate or nitrite accelerators to the alcohol achieves a level of auto-ignition sufficient to operate in diesel engines.
