1,129,782. Tetrahydropyrimidines; amine succinamaies. MOBIL OIL CORP. 4 Jan., 1967 [10 Jan., 1966], No. 471/67. Heading C2C. [Also in Division C5] Tetrahydropyrimidines of formula where R is a C 8 -CSP2/SP substituted or unsubstituted aliphatic hydrocarbon radical and R 1 is a C 1 -C 22 substituted or unsubstituted aliphatic hydrocarbon radical are prepared by condensing a straight-chain carboxylic acid having a C 1 -C 22 aliphatic hydrocarbon radical with a straight chain diamine having a C 8 -C 22 aliphatic hydrocarbon radical may be added to lubricants. The examples describe the reaction of tallow N-alkyl trimethylene diamines with palmitic and hydroxyphenyl stearic acid, oleyl diamine with palmitic and oleic acid, arachidylbehenyl diamines with iso-stearic acid and N- aminopropyl oleyl amine with palmitic acid. Amine salts of (a) succinamic acids of formula where R 2 is a C 4 -C 30 aliphatic hydrocarbon radical having a tertiary carbon atom attached to the nitrogen atom; and (b) a C 4 -C 30 primary mono-alkyl amine having a tertiary carbon atom attached to the nitrogen atom may be added to lubricants or fuels.
