A process for continuous preparation of halogenated alkoxyethane of general formula XClHC—CF.sub.2OR, where X is —Cl or -f and OR is C.sub.1-4 alkoxy, the process comprising a step of introducing in a flow reactor reaction components comprising (i) a compound of general formula XClHC—CYF.sub.2, where each of X and Y is independently —Cl or —F, (ii) a base, and (iii) a C.sub.1-4 alkanol, wherein a) the flow reactor comprises one or more tubular flow line(s) through which the reaction components flow as a reaction mixture, c) the halogenated alkoxyethane is formed at least upon the reaction components mixing, with the so formed halogenated alkoxyethane flowing out of the flow reactor in a reactor effluent, and b) the base is one that forms a salt soluble in the alkanol during formation of the halogenated alkoxyethane.

A process can be used for recovering 1-methoxy-2-propanol and 2-methoxy-1-propanol from an aqueous effluent stream by liquid-liquid-extraction, followed by extractive distillation, distillation of methoxypropanols from the extraction solvent, and distillative separation of the methoxypropanol isomers. Recovered extraction solvent is recycled to the extraction and extractive distillation. Heat transfer from recovered extraction solvent to the extract fed to the extractive distillation reduces energy demand of the process. A facility for this process contains a countercurrent extraction column, an extractive distillation column, a solvent recovery distillation column, an isomer separation distillation column, and a heat exchanger for transferring heat from recovered extraction solvent to the extract fed to the extractive distillation.

Disclosed herein is a method of making polymerizable bio-based monomers containing one phenolic hydroxyl group which has been derivatized to provide at least one polymerizable functional group which is an ethylenically unsaturated functional group (such as a [meth]acrylate group), where the precursors of the polymerizable bio-based monomers are derived from raw lignin-containing biomass. Also disclosed herein are bio-based copolymers prepared from such bio-based monomers and a co-monomer, and methods of making and using such bio-based copolymers. In particular, the bio-based copolymers can be used as pressure sensitive adhesives, binders, and polymer electrolytes.
