This invention relates to certain compounds which are N-fatty acyl derivatives of primary and secondary amine and N-substituted acyl derivatives of primary and secondary amines which have exhibited utility as base lubricants, extreme pressure lubricants or lube additives. More particularly, this invention relates to N- and NN-disubstituted long chain allphatic amides the acyl component of which is a normal, branched, or substituted alkenoic or alkanoic acyl group containing from 16 to 22 carbon atoms the amide nitrogen of which may be derived from an alkyl amine, dialkyl amine, alkyl-alkoxyalkylamine, dialkoxyalkylamine or nitrogen heteroalicyclic. Typical amines are butylamines, dibutylamines, N-methyl-alkoxyethyl amine, diethoxyethyl amine, and morpholine. The acyl substituent referred to may be divalent sulfur or pentavalent phosphorous.
We have discovered that many of the simple N-alkyl and N,N-dialkyl or N-alkyl-N-alkoxyalkyl amides of the C to C alkeneoic or alkanoic fatty acids are good base lubricants. We have further discovered that the introduction of divalent sulfur into the fatty acid moiety imparts excellent extreme pressure lubricant characteristics to such compounds. We have also found this to be true for glycerides and simple esters even when the divalent sulfur substituent group is in the alkyl moiety. ln particular we have found the epithio group to be most effective. We have also observed that the introduction ofboth hydroxy and alkyl phosphato groupings alpha to each other also imparts extreme pressure lubricant characteristics to the compound.
1n addition it was noted that the above hydroxyphosphato compound and its mercapto analog N- [9( 10 )-mercapto-(9) lO-dibutylphosphato]stearamide were effective antiwear compounds and additives.

methoxyisopropyloleamide, N-methoxyethyloleamide.

EXAM PLE l8 9,10-Epithiostearyl 9,10-epithiostearate 140 grams of a commercial oleic acid (Emersol 233LL), 119 g of commercial oleyl alcohol (Aldol 85) and 50 ml of toluene were refluxed in the presence of 3 g of p-toluene sulfonic acid-for 24 hours, with a continual removal ofthe water of reaction by a Dean-Stark trap. The reaction mixture was freed of p-toluene sulfonic acid and any unreacted fatty acid by repeated washings with aqueous NaHCO solution. The product, oleyl oleate, was isolated by stripping off the toluene from the Na S0, dried mixture.
The oleoyl oleate was converted to 9,10-epoxystearyl 9,10-epoxystearate by treatment with a chloroform solution of meta-chloroperbenzoic acid containing 5% excess of per acid over that theoretically necessary to epoxidize the two double bonds present per mole of oleoyl oleate. The product 9,10-epoxysteary1 9,10- epoxystearate had an oxirane content of 4.99.
112 g of the 9,10-epoxysteary1 9,10-epoxystearate was converted to 9,10-epithiostearyl 9,10-epithiostearate by the dropwise addition of a l-4 dioxane solution (300 ml dioxane) of the former over a 2-2-V2 hour period to a vigorously stirred aqueous solution containing 34.2 g of thiourea in minimal water and 22.0 g of H50 as a 30% aqueous solution maintained at a temperature of 5C.
EXAMPLE l9 Epithioated Soybean Oil 300 grams of a commercially available epoxidized soybean oil (oxirane content 7.1%) was dissolved in 500 ml of 1-4 dioxane and added dropwise over a 2 hour period to a vigorously stirred solution composed of 101.2 gof thiourea in minimal water and 65.0 g of H (the latter as a 30% aqueous solution), maintained at 5C. After the addition was completed the reaction mixture was raised to 40C and kept stirred for 2 hours as it cooled. 70.6 g of Na C0 in the form of a 10% aqueous solution was added with stirring and the mixture warmed up to 40C and stirring continued for 1 hour. The epithioated soybean oil was then extracted with 200 ml of benzene and the extract washed, dried,
and the benzene stripped off. The recovered oil had a sulfur content of 6.97% as opposed to a theoretical value of 13.25% for total conversion of oxirane to thilrane.
EXAMPLE 20 Epithioated Jojoba oil g of jojoba oil (1 V 83.6) was epoxidized by the addition of 133.0 g of m-chloroperbenzoic acid in 1,500 ml of CHCl while maintaining a temperature of 20-25C to an oxirane content of 3.56%. The recovered product (131 g of epoxide) was converted to the epithio analog by its reaction with 30.9 g thiourea and 66.6 g of H S0 following the same reaction procedure described in Example 19. The reaction mixture was treated with 21.5 g of Na C0 in 195 ml of H 0 following the procedure of Example 19 and the epithio analog recovered as described in the previous example. The thiirane content (epithiosulfur) was 2.31%. Complete conversion of oxirane to thiirane should have given 6.87% sulfur.

IV. The epoxy polyester 111, 100 g, in 200 ml of dioxane was added dropwise over a 2-3 hour period to 6.4 g of thiourea in minimal water to which had been added 4.2 g of H S as a 30% aqueous solution.
