Disclosed herein is the reaction product of 5-amino-2-mercapto-1,3,4-thiadiazole with hydrocarbyl epoxides. The resulting reaction product finds use as an additive in lubricating oil compositions.

Lubricant additives derived from aminomercaptothiadiazole and lubricant

Certain partial esters of phthalic acid provide effective rust inhibition for greases and other solid lubricants.

Anti-rust compositions

Certain partial esters and amides provide effective rust inhibition for greases and other solid lubricants.

Water soluble lubricant compositions comprising alkanolamine and organic acid are improved by employing as the organic acid a partial acid amide of a dicarboxylic acid, such as mono-PRIMENE 81 R amide of succinic acid, mono-di-2-ethylhexylamide of maleic acid, mono-di-2-ethylhexylamide of methyltetrahydrophthalic acid and mono-di-2-ethylhexylamide of methylhexahydrophthalic acid as the organic acid.

Water soluble lubricant compositions

Water soluble lubricant compositions comprising alkanolamine and organic acid are improved by employing a monocycloalkyl-1,2,3,6-cis tetrahydrophthalate or hexahydrophthalate; or a monoaralkyl-1,2,3,6-cis tetrahydrophthalate or hexahydrophthalate as the organic acid.

Metal working lubricant containing an alkanolamine and a cycloaliphatic

1-hydroxyethyl-1-alkyl-2-imidazolines, bis-imidazolines and their derivatives impart good detergent properties to liquid hydrocarbon fuels containing a minor effective amount thereof.

Detergent compositions

Improved water soluble lubricant compositions are provided by incorporating therein amides derived from alkylamines and succinic, tetrahydrophthalic or tetrahydrofuran tetracarboxylic acids.

Aqueous lubricant compositions

Water soluble lubricant compositions comprising alkanolamine and organic acid are improved by employing a monocycloalkyl-1,2,3,6-cis tetrahydrophthalate or a monoaralkyl-1,2,3,6-cis tetrahydrophthalate as the organic acid.

A motor fuel in the form of a microemulsion is provided comprising a mixture of gasoline, methanol and water and a surfactant blend having a hydrophile-lipophile balance value of from about 3 to about 4.5.
