Definitions

  • the present invention relates to improved lubricating oils, ,especially to oils of higher re ment in one respect is detrimental in the other.
  • the aromatic ring may be phenolic or of the l0- condensed form such as naphthalene or anthracene and the alkylated aromatic rings may also be used. Hydroxyl or amino groups may be present on the ring without .detrimentally afiecting the value of the compounds. Often indeed it is 35 found to be improved by their presence.
  • the aromatic-sulpho-radlcal may be present in the alcoholic or the acidic portion of the ester molecule and more than one of these groups is oftendesirable.
  • the alcoholic portion of the i0 ester may be an aromatic alcohol or phenol or it may be an aliphatic radical containing a substituted sulpho-aromatic group. It may be mo'iiohydric or polyhydric aswill be illustrated below.
  • the acidic portion of the ester molecule may 15 contain the sulpho-arom'atic group whether or not such a group is a part of the. alcoholic radical.
  • Mono or poly basic acids may be employed.
  • esters are for the most part freely soluble in lubricating oils, but only relatively small quantitles are necessary for the present purposes.
  • a gen-absorption is determined at 15 minute intervals by notingv the volume; of the undissolved oxygen.
