ALKYL POLY GLYCOL-ETHERS AND THEIR SYNTHESIS

摘要

Processes for producing long chain ethers by reacting a long chain secondary alcohol, a long chain alkoxide, or a combination thereof with at least one epoxide. The long chain ether may comprise a long chain ether alcohol, a long chain ether alcoholate, or a combination thereof. The long chain ether alcoholate may be either protonated to provide the long chain ether alcohol or reacted with an alkyl halide to provide a long chain capped ether. Long chain ether compositions are also disclosed herein.

1. A process to make a long chain ether lubricant, comprising:
a) providing a first reactant comprising a material selected from the group consisting of a long chain secondary alcohol, a long chain alkoxide, and combinations thereof; and b) reacting the first reactant with at least a first epoxide to provide a long chain ether intermediate selected from the group consisting of a long chain ether alcoholate of general Formula IIA, a long chain ether alcohol of general Formula IIB, and combinations thereof:wherein:
R1′ and R2′ are independently selected from the group consisting of C5-C21 linear or branched alkyl and C5-C21 linear or branched alkenyl, R3 and R4 are independently selected from the group consisting of a hydrogen atom, C1-C35 linear or branched alkyl, and aryl, and n is an integer from 1 to 50; and c) preparing the long chain ether lubricant from the long chain ether intermediate;wherein the long chain ether lubricant has a Viscosity Index from 120 to 230.
