Embodiment 1

[0293] Embodiment 1: Butyl oleoyl sarcosinate (BuOS)

[0294] 281 g (0.8 mol) oleoyl sarcosine, 237 g butanol and 0.38 g Amberlyst 15 acid resin were added to a 1 L 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 and filtered to obtain 310 g of product.

Embodiment 2

[0295] Embodiment 2: Ethyl oleoyl sarcosinate (EtOS)

[0296] 281 g (0.8 mol) oleoyl sarcosine and 295 g ethanol were added to a 1 L 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 280 g of product.

Embodiment 3

[0297] Example 3: Ethyl lauroyl sarcosinate (EtLS)

[0298] 128.5 g (0.5 mol) lauroyl sarcosine and 345.5 g ethanol were added to a 1 L 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 composition 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) (see formula III) wherein 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; and X is an alkali metal, alkaline earth metal, or ammonium cation and n is the valence of cation X; and (B) at least one metal dialkyl dithio phosphate salt.

Description

Background technique [0001] 1. technical field [0002] 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 motor oils containing acyl N-methylglycine and derivatives thereof and one or more metal dialkyl dithiophosphates. [0003] 2. Description of related technologies [0004] To ensure smooth running of the engine, engine oil plays an important role in lubricating various sliding parts in the engine such as piston rings / cylinder liners, bearings for crankshaft and connecting rods, valve mechanism including cams and valve lifters, etc. . Motor oil also plays a role in cooling the inside of the engine and dispersing the products of combustion. Other possible functions of motor oils may include preventing or reducing rust and corrosion. [0005] The principle study of motor oil is to prevent wear and seizure of compone...
