A process for extracting boron from aqueous boron containing solutions by contacting the aqueous solution with a substantially water immiscible salicylic acid derivative or a salt thereof, nuclear substituted with an alkyl, aryl, alkaryl, or cycloakyl radical wherein the derivative has at least 11 carbon atoms in a water immiscible solvent comprising isoamyl alcohol in the range of from 10 to 100 percent by volume. Preferably, the balance of the solvent is an inexpensive water immiscible petroleum cut. Boron is sequestered by the salicylic acid derivative and the isoamyl alcohol has a synergistic effect in enhancing the proportion of boron extracted.
