  • Patent number: 4346233
    Abstract: This disclosure relates to a process for preparing long-chain hydrocarbon substituted ureas by reacting a long chain fatty acid N-chloramide in isopropanol and/or tertiary butanol with an aliphatic or araliphatic primary or secondary amine in the presence of an alkali or alkaline earth hydroxide at a temperature of from 20.degree. to 100.degree. C. The process of this disclosure is particularly useful in preparing long-chain hydrocarbon substituted ureas wherein one of the aliphatic hydrocarbon substituents contains one or more hydroxyl and/or carboxyl groups, as well as the salts of such substituted ureas.

  • Patent number: 4323495
    Abstract: Novel branched-chain monoalcohols and derivatives thereof are disclosed. Such derivatives are selected from the group consisting of(a) esters of aromatic, aliphatic or cycloaliphatic acids having at least 2 carbon atoms and 1, 2 or 3 carboxyl groups;(b) urethanes of aromatic, aliphatic or cycloaliphatic isocyanates;(c) monoethers of polyalkylene oxide glycols having 2 to 50 alkylene oxide units each containing 2 or 3 carbon atoms and the alkylpolyoxyalkylene sulfates derived therefrom;(d) sulfates.The branched-chain monoalcohols are obtained by reduction of branched-chain monocarboxylic acids or esters thereof. Said acids are telomeric acids obtained by the free radical addition of 1 mole of acetic anhydride to at least three moles of hexene and/or higher olefins containing up to 30 or more carbon atoms (C.sub.30+) in the presence of a trivalent manganese compound. The products of this invention are suitable for use in engine lubricating oils, lubricant compositions for polymers and wax compositions.
