The more toxic isomers contain the Z and E stereoisomers of hydrofluoroolefins, and in order to minimize the toxic effects in the applications to be used, for example cooling and thermal fluids, foam blowing agents or solvents, A combination is disclosed that is less than about 30% by weight of the combination. Also disclosed is a method of obtaining a combination containing Z and E stereoisomers of hydrofluoroolefins. |
