摘要:A rare earth metal extractant in the form of a dialkyl diglycol amic acid is synthesized by reacting diglycolic anhydride with a dialkylamine in a synthesis medium. A molar ratio (B/A) of dialkylamine (B) to diglycolic anhydride (A) is at least 1.0. A non-polar or low-polar solvent in which the dialkyl diglycol amic acid is dissolvable is used as the synthesis medium.

摘要:A rare earth metal extractant in the form of a dialkyl diglycol amic acid is synthesized by reacting diglycolic anhydride with a dialkylamine in an aprotic polar solvent, with a molar ratio of dialkylamine to diglycolic anhydride being at least 1.0, and removing the aprotic polar solvent.

摘要:Nanocrystals are synthesized with a high degree of control over reaction conditions and hence product quality in a flow-through reactor in which the reaction conditions are maintained by on-line detection of characteristic properties of the product and by adjusting the reaction conditions accordingly. The coating of nanocrystals is achieved in an analogous manner.

摘要:A method of synthesizing nanoparticles includes: combining at least one stabilizing agent, at least one precursor and an ionic liquid to form a reaction mixture; heating the reaction mixture to a predetermined temperature to form the nanoparticles and cause the nanoparticles to self-separate from the reaction mixture; and collecting the nanoparticles from the reaction mixture. Ionic liquid from which the nanoparticles are separated may be reused.
