Monocyclic Acid Moiety Patents (Class 560/103)
  • Patent number: 5171915
    Abstract: It is disclosed that aromatic compounds can be alkylated with mono-olefinic HVI-PAO dimer in contact with an acidic catalyst to produce novel alkylated aromatic compositions. It has been found that the novel HVI-PAO dimer alkylated aromatic compositions exhibit an extraordinary combination of properties relating to low viscosity with high viscosity index and low pour point which renders them very useful as lubricant basestock. Further, it has been found that the novel alkylaromatic compositions of the present invention show improved oxidative stability. Depending upon the substituent groups on the aromatic nucleus, useful lubricant additives can be prepared for improved antiwear, antioxidant and other properties. HVI-PAO dimer is prepared as a product or by-product from 1-alkene oligomerization using reduced chromium oxide on solid support.

  • Patent number: 4833247
    Abstract: A process for the production of 2-benzyl fatty acids and esters thereof corresponding to the following formula ##STR1## comprising reacting 2-fatty alkyl-4,4-dimethyl-2-oxazolines with benzaldehydes corresponding to the formula R.sup.2 --C.sub.6 H.sub.4 --CHO to form 2-(1-benzylidene)-fatty alkyl-4,4-dimethyl-2-oxazolines, catalytically hydrogenating the products of this reaction to the 2-(1-benzyl)-fatty alkyl-4,4-dimethyl oxazolines and converting the products thus formed by acid-catalyzed hydrolysis or solvolysis with an alcohol of the formula R.sup.5 OH into the 2-benzyl fatty acids or esters thereof. Amidosulfonic acid gives particularly high yields as catalyst for the reaction of the 2-fatty alkyl-4,4-dimethyl-2-oxazolines with the benzaldehydes.

  • Patent number: 4791097
    Abstract: A method is provided for modifying foam in an aqueous surfactant composition. The method comprises admixing with the aqueous surfactant composition a foam modifying amount of a composition of the formula: ##STR1## wherein R is: (a) a branched or linear alkyl of 20 to 28 carbon atoms; or(b) ##STR2## wherein n is 9-16 and R.sub.1 is a branched or linear alkyl of 3 to 22 carbon atoms.Certain of these benzoate esters are novel, in particular: ##STR3## wherein R.sub.2 and R.sub.3 are each, independently, an alkyl of 4 to 16 carbon atoms, and the total number of carbon atoms in R.sub.2 and R.sub.3 is at least 12 carbon atoms. Preferably, R.sub.2 and R.sub.3 are each C.sub.8 H.sub.17, i.e. octyldodecyl benzoate ester.Additional novel benzoate esters used as foam enhancers have the formula: ##STR4## wherein n is 12 to 16 and R.sub.1 is a branched or linear alkyl of 3 to 22 carbon atoms. Particularly preferred esters are when n is 14, R.sub.1 is C.sub.18 H.sub.37 and R.sub.1 is C.sub.4 H.sub.9.
