example

[0050] This example illustrates long chain alkoxyboroxanes that have demonstrated the ability to improve the performance of dispersants on FKM elastomers in static seal testing. See ASTM D1418. The dodecanol (about C12) form of boroxane was synthesized as follows:

[0051] A 500 mL round bottom flask equipped with a dean stark apparatus and under nitrogen was charged with 200 mL of toluene. To this was added 1 mole of boric acid. At 70°C, 1 mole of dodecanol was added in one portion and the reaction mixture was then heated to reflux. The reaction mixture was kept at reflux for at least 4 hours and 2 moles of water were collected. The Dean Stark trap was replaced with a short path distillation head and the toluene was removed by distillation. Once the solvent was removed, the reaction mixture was continued to dry by drawing a vacuum of 28 mmHg for 2 hours while increasing the temperature to 140°C. Once held for 2 hours, the product (Product 1) was removed from the heat and...

Abstract

The present invention generally relates to compositions for lubricating oils. In certain aspects, the present invention generally relates to boroxane compounds having alkyl groups, wherein one or more of the alkyl groups contains at least 8 carbon atoms. Such compounds may exhibit increased hydrolytic stability compared to other boroxane compounds. Such boroxane compounds can be used, for example, to improve seal compatibility in engines. Other aspects of the invention generally relate to systems and methods for making such boroxane compounds, engine oils containing such boroxine compounds, methods of using such boroxine compounds, and the like.

Description

[0001] Related applications [0002] This application claims the benefit of US Provisional Patent Application No. 62 / 254,016, filed November 11, 2015, entitled "Boroxane-Based Seal Compatibilizers," which is incorporated herein by reference in its entirety. technical field [0003] The present invention generally relates to compositions for lubricating oils. Background technique [0004] Boroxanes are 6-membered heterocyclic compounds composed of alternating oxygen and individually hydrogenated boron atoms. Oxygen atoms can be bonded to various alkyl groups. Boroxanes can be used, for example, in lubricating oils to improve various performance characteristics, such as reducing the ability of certain amine compounds to attack fluoropolymer seals in engines. However, such compounds are often hydrolysis sensitive and, therefore, there is a need for improved boroxane compounds. SUMMARY OF THE INVENTION [0005] The present invention generally relates to compositions for lu...
