Preparation of bis-(1-bromo-2,3,3-trichloro-2-propenyl) ether
摘要:
Bis-(1-bromo-2,3,3-trichloro-2-propenyl) ether of the formula ##STR1## is produced by reacting bis-(2,3,3-trichloro-2-propenyl) ether of the formula ##STR2## with bromine under irradiation with light. The end product as produced may be steam distilled in situ, thereby recovering 2,3,3-trichloroacrolein.
