    摘要: Improved methods for making ethers. In particular, an alkoxide can be more effectively converted into an ether by reaction with a hydrocarbyl halide in the presence of a substantial excess of a hygroscopic base such as NaOH. When present in such an unconventional excess, the base serves multiple functions. As a consequence, the alkoxide is extensively converted to the desired ether rapidly at excellent yields. The reaction environment also aids later product isolation. The use of the NaOH rather than Na metal allows the ether product to be separated from water soluble impurities such as salt products, left over base, left over hydrocarbyl halide, formates, etc. by liquid-liquid extraction among aqueous and organic phases.

    摘要: Various embodiments of the present invention are directed to processes and methods for converting lipids comprising fatty acids into fatty esters. According to various embodiments of the invention, the saponifiable lipids are reacted with a base to form alkali soaps. The alkali soaps are then reacted with an acid to form fatty esters. Both the base reaction and the acid reaction may occur in the presence of one or more alcohols. Following the acid reaction, a solvent may be added to effect a separation of the fatty esters, which may then be recovered.
