Abstract: A process is disclosed for selectively sorbing contaminating amounts of isopropyl alcohol from diisopropyl ether by contacting with a high surface area strong acid type cation exchange resin in the hydrogen form, preferably having a mean pore diameter in the range from about 40 to about 259 Angstroms.

Abstract: A process for the continuous production of di- and/or epichlorohydrin is disclosed wherein impurities, e.g., chloroaliphatic alkanes and chloroaliphatic ethers are removed by energy efficient solvent extraction and are obtained in relatively concentrated form for further processing or disposal.

Abstract: A process is described which accomplishes improvement in the quality of the chlorine product of brine electrolysis. One or more objectionable impurities are eliminated from said chlorine through contact with hydrogen chloride, or an equivalent combination of hydrogen and chloride ions, in dilute solution.

Abstract: Chlorohydrin reactant mixtures containing epichlorohydrin and mono- and dichlorohydrins are selectively hydrolyzed to glycerine by contact with an alkali metal carbonate catalyst, preferably sodium carbonate, at a temperature of about 50.degree. to 70.degree. C for a period of from about 20 to about 150 hours in a two phase agitated reaction system comprising an aqueous phase containing at least about 0.5% by weight alkali metal carbonate and an organic solvent phase having less than about 0.5% weight solubility in water and a dielectric constant of less than about 10, said aqueous phase being about 0.5 to about 10 times the volume of the organic solvent phase.
