Abstract
A method of alkoxylating a humus material comprising heating a reaction mixture comprising a humus material, a C3+ cyclic ether, a catalyst and an inert reaction solvent, and recovering a C3+ alkoxylated humus material from the reaction mixture. A method of alkoxylating a humus material comprising heating a reaction mixture comprising a humus material, a C3+ cyclic ether, a catalyst and an inert reaction solvent to a temperature of from about 130° C. to about 170° C., wherein the humus material comprises leonardite, the C3+ cyclic ether comprises propylene oxide, and the inert reaction solvent comprises xylene, and recovering a C3+ alkoxylated humus material from the reaction mixture. A C3+ alkoxylated humus material.
