  • Dispersants for lubricating oil
    Patent number: 5587432
    Abstract: Novel ashless dispersants that have reduced reactivity toward fluoroelastomers are described. They are oil-soluble products obtained by a process which comprises reacting (i) a long chain succinic acylating agent wherein the long chain is derived from a polyolefin with (ii) an alkoxylated diethylene triamine having an average of from 1 to 2 N-substituted C.sub.2 or C.sub.3 hydroxyalkyl groups per molecule. These reactants being employed in proportions of at least 2 moles of the acylating agent per mole of the alkoxylated diethylene triamine, with the proviso that where the average of N-substituted C.sub.2 or C.sub.3 hydroxyalkyl groups is 1.7 or more, the proportions are such that there are more than 2 moles of the acylating agent per mole of the alkoxylated diethylene triamine.
    Type: Grant

    Date of Patent: December 24, 1996
    Assignee: Ethyl Petroleum Additives Limited
    Inventor: Roger Scattergood
  • Modified dispersant compositions
    Patent number: 5505868
    Abstract: An oil soluble dispersant composition formed by reacting a basic nitrogen-containing ashless dispersant (i) with at least one dibasic acylating agent, (ii) with at least one phosphorus compound, and (iii) with at least one boron compound, said reactions (i), (ii) and (iii) being conducted concurrently or sequentially in any order such that the initial ashless dispersant is chemically modified via acylation in (i), by phosphorylation in (ii), and by boronation in (iii).

  • Production of phosphorothioate salts
    Patent number: 5210261
    Abstract: Amine salts of phosphorothioic acids, useful for example in lubricant compositions, are made by forming a mixture of sulphur and an amine, and then adding a phosphite ester. The reaction is controlled by the rate of addition of the ester.
