Embodiment 1

[0310] Embodiment 1: Butyl oleoyl sarcosinate (BuOS)

[0311] 281 g (0.8 mol) oleoyl sarcosine, 237 g butanol and 0.38 g Amberlyst 15 acid resin were added to a 500 mL resin kettle equipped with overhead stirrer, Dean Stark separator and thermocouple. The reaction mixture was heated at reflux under nitrogen with stirring for 3 hours, removing 25 mL aliquots every 30 minutes. The reaction mixture was then concentrated under vacuum and filtered to obtain 310 g of product.

Embodiment 2

[0312] Embodiment 2: Ethyl oleoyl sarcosinate (EtOS)

[0313] 281 g (0.8 mol) oleoyl sarcosine and 295 g ethanol were added to a 500 mL resin kettle equipped with overhead stirrer, Dean Stark separator and thermocouple. The reaction mixture was heated at reflux under nitrogen with stirring for 3 hours, removing 25 mL aliquots every 30 minutes. The reaction mixture was then concentrated under vacuum to obtain 280 g of product.

Embodiment 3

[0314] Example 3: Ethyl lauroyl sarcosinate (EtLS)

[0315] 128.5 g (0.5 mol) lauroyl sarcosine and 345.5 g ethanol were added to a 500 mL resin pot equipped with overhead stirrer, Dean Stark separator and thermocouple. The reaction mixture was heated at reflux under nitrogen with stirring for 3 hours, removing 25 mL aliquots every 30 minutes. The reaction mixture was then concentrated under vacuum to obtain 126.2 g of product.

Abstract

A lubricating oil comprising a major amount of base oil and a minor amount of an additive package, wherein the additive package comprises: (A) a friction modifier component selected from: (a) one or more a reaction products of an alcohol with a compound of the formula IV: (see formula IV) and (b) one or more compounds of the Formulae II-III: (see formula II); and (see formula III) wherein R is a linear or branched, saturated, unsaturated, or partially saturated hydrocarbyl having about 8 to about 22 carbon atoms, R2 and R3 are independently selected from hydrogen C1-C18 hydrocarbyl groups, and C1-C18 hydrocarbyl groups containing one or more heteroatoms; X is an alkali metal, alkaline earth metal or ammonium cation and n is the valence of cation X, and reaction products of amines, amino alcohols, alkali or alkaline earth metal hydroxides, alkali or alkaline earth metal oxides and mixtures thereof with compounds of the Formula IV: (see formula IV) wherein R is as defined above; and (B) at least one friction modifier that is different from the one or more compounds (A).

Description

technical field [0001] The present disclosure relates to additive compositions and lubricants containing acyl N-methylglycine and derivatives thereof. In particular, the present disclosure relates to additive compositions and lubricating oils containing acyl N-methylglycine and derivatives thereof and at least one friction modifier. Background technique [0002] Boundary layer and thin film friction can be important features in the lubrication of sliding parts of various devices such as engines. Therefore, it is desirable to develop alternative lubricating oils that address these characteristics. [0003] For example, to ensure smooth operation of the engine, oil plays an important role in lubricating various sliding parts in the engine such as piston rings / cylinder liners, bearings of the crankshaft and connecting rods, valves including cams and valve lifters institutions etc. Motor oil also plays a role in cooling the inside of the engine and dispersing the products of ...
