Definitions

  • Preferred compounds of the above formula are those in which R is hydrogen or C 1 -C 4 -alkyl, R i C 6 ⁇ C 18 -alkyl or C 6 ⁇ C 18 -atkenyl, A is a group of the formula X denotes a number from 1 to 9 and the numerical value for m is chosen so that the total content of ethylene oxide in the molecule is 40 to 200 ethylene oxide units.
  • the novolak thus obtained is introduced into an autoclave together with 1.1 g of sodium hydroxide.
  • the air is displaced by nitrogen and it is heated to 150-170 ° C.
  • liquid ethylene oxide or a mixture of ethylene oxide and propylene oxide is introduced until the weight increase in the autoclave has reached the total molar amount indicated under A in the table. Then it is stirred for another hour.
  • a mixture of the oxyalkylated novolak, a catalytically effective amount of p-toluenesulfonic acid and the amount of acid of the formula R L -COOH required in each case are introduced into a stirred vessel equipped with a stirrer and cooler, and the mixture is stirred at a temperature of about 170 for as long as possible ° C heated until no more water distilled off and the acid number has dropped to a value below 3.
  • the esterification product is thus obtained in the form of a brown substance with an oily to waxy consistency.
  • esterified oxalkylated novolaks required for the production of the metalworking agents according to the invention can vary within wide limits.
  • the friction wear balance according to Reichert was used.
  • This device essentially consists of two interchangeable steel friction partners of different hardness, one of which, a slip ring, is movable and the other, a test roller, is rigidly arranged.
  • the slip ring and test roller are pressed axially crossed on each other using a double lifting system with a defined force.
  • the slip ring is partially immersed in the metalworking fluid to be examined and at the same time executes a rotary movement, with constant lubricant transport to the wear zone between the test roller and the test ring being guaranteed.
  • the metalworking fluids were produced by dissolving the active substances in drinking water of 20 ° dH.
