STH epichlorohydrin for hromatogr. (3 ml)

Epichlorohydrin (1-chlorine-2,3-epoxypropane; chlormethyloxirane) - colorless liquid with sharp off-flavor. Let's well dissolve in organic solvents; restrictedly it is dissolved in water. Epichlorohydrin easily attaches HCl at usual temperature, forming 1,3 dihlorohydrin of glycerin. It is capable to enter condensation with bisphenol-Ç, forming dianovy epoxies. At epichlorohydrin polymerization, depending on conditions and catalysts, rubbers are formed.

Receiving.
  • dehydrochlorination of dihlorohydrins of glycerin: 4-5% aqueous solution of mother substances with Ca(OH)2 is heated to 100 °C. The formed epichlorohydrin is quickly brought out of reaction zone for prevention of further transformations.
  • allyl chloride epoxidation by organic hydroperoxides, for example, rubs - butylhydroperoxide in the presence of complex compounds of molybdenum at 100 °C;

  • Application.
  • epichlorohydrin - intermediate compound when receiving synthetic glycerin;
  • for receiving epoxies, ion exchange resins;
  • at synthesis of epichlorhydrin rubbers;
  • as mother substance when receiving pharmaceuticals, number of derivatives of glycerin, detergents, lubricants, emulsifiers, glues;
  • as solvent for cellulose, pitches, dyes and pesticides;
