Embodiment

[0092] The present invention is further described by the following examples, which are not to be construed as limiting the scope of the present invention. The invention can be further understood in the following non-limiting preparations and examples.

Embodiment and

[0093] Synthetic Examples and Preparations:

[0094] In the appended examples all temperatures refer to the degree Celsius system, and the term "room temperature" refers to about 20-25°C. The term "percent or %" refers to wt%, and the term "mole" or "mol" refers to gram mole. The term "equivalent" means that the amount of reactant, expressed in moles, is equal to the previous molar amount of the subsequent reactant described in the described example as a finite mole or a finite weight or volume. Proton nuclear magnetic resonance (NMR) was determined at 300 mHz.

[0095] Olefin Isomerization Step

preparation Embodiment 1

[0096] Preparation Example 1: Isomerization of C12α-Olefins

[0097]

[0098] An alpha-olefin (C12 is used here as an example) is isomerized with iron pentacarbonyl, as a result of the isomerization the double bonds of the starting material (C12 alpha-olefin) are now distributed internally along the carbon chain.

[0099] 180 grams of C12 alpha-olefin were dried overnight under nitrogen over 50 grams of molecular sieves (25 grams of 3A and 25 grams of 4A) and transferred to a 1 L reaction flask. Inject 0.8 mL of Fe(CO) into the flask 5 . The reaction mixture was then heated in an oil bath at 175°C for 4 hours under nitrogen. IR evidenced that the reaction was complete. The oil bath temperature was lowered to 85 °C. 7.5 g of silica gel and 10 drops of methanesulfonic acid were added, and the mixture was stirred overnight. The brown oil in the flask was filtered on a pad of silica and a colorless liquid was obtained as Compound 1. NMR (CDCl 3 )δ5.4(m,2H);2.0(m,4H);1.35(m...

Abstract

Disclosed are a friction modifier composition and a method of lubricating an internal combustion engine, the method comprising providing the engine with an oil of lubricating viscosity and 0.25-5% by weight of the friction modifier composition based on the total mass of the lubricating oil composition, The friction modifier composition comprises: a) an aminoalcohol reaction product prepared by isomerizing C using at least one solid or liquid catalyst 12 -C 30 normal α-olefins to form internal olefins; epoxidation of said olefins; and reaction with mono- or di-hydroxyalkylamines; b) glycerol with C containing 0-3 double bonds 12 -C 22 Esters of carboxylic acids.

Description

technical field [0001] Lubricating oil compositions often employ friction modifier compounds to modify the frictional properties of the composition, potentially improving fuel economy for internal combustion engines. Background technique [0002] While motor vehicle manufacturers continue to seek improved fuel economy through engine design; new methods of formulating engine oils have played a significant role in improving fuel economy and have resulted in motor vehicles with improved emissions characteristics. Optimizing lubricants is particularly preferred with respect to engine hardware changes due to their relatively low unit cost in terms of fuel efficiency and possible backwards compatibility with older engines. As a result, formulators are under constant pressure to develop engine oils and additive packages that utilize new performance base stocks and additive blends that have demonstrated superior performance over conventional formulations. Good fuel efficiency, oxid...
