Abstract
Compounds are prepared having the formula X -- B -- [--O--A--].sub.n X' (hereinafter referred to as AAE's), wherein X and X' are chlorine or bromine atoms, n is an integer from 1 to about 4, A is a vicinal alkylene group of up to about 8 carbon atoms and may bear a phenyl, chlorine, bromine or hydroxy substituent, and B is a vicinal alkylene group of from 8 to about 18 carbon atoms and may bear a chlorine, bromine or aromatic substituent. The above compounds are prepared by reacting the halogen XX' with a mixture of the B mono-olefin (hereinafter BMO) and the epoxide AO. The compounds are useful as solvents and dielectric fluids.
