Applicazioni

Epichlorohydrin is used in the manufacture of polyamines and polyquaternary ammonium salts, as flocculents in water and wastewater treatment. It is used in the synthesis of surface active agents for washing products and toiletries. Polyamine-epichlorohydrin resin is used in paper industry to improve paper wet-strength. It acts as a chemical intermediate and widely used in the manufacture of epoxy resins, epichlorohydrin elastomers and polyamide-epichlorohydrin resins.

Note

Keep away from sources of ignition. Keep container tightly closed in a dry and well-ventilated place.

For use as an acid scavenger in bromination reactions, see: J. Am. Chem. Soc., 95, 4419 (1973).

The preparation of glycidyl ethers, often carried out in two steps, via the ring-opened chlorohydrin ether and subsequent ring-closure with base, can be achieved as a single step, under phase-transfer conditions: Synthesis, 117 (1983). For extension to diglycidyl ethers of diols, see: Synthesis, 649 (1985).

Reaction with primary amines provides a one-step route to 3-azetidinols: J. Org. Chem., 55, 2920 (1990):
