Abstract

The invention relates to a method for synthesizing citricacide-titatnium chelate by a microwave chelation process by using new metatitanic acid precipitate. The method is characterized in that: the new metatitanic acid precipitate is prepared by neutralizing an iced solution of titanium salt by using alkali; the new metatitanic acid precipitate replacing titanium chloride and sulfate is used as raw materials for synthesizing the citricacide-titatnium chelate; and the citricacide-titatnium chelate is synthesized by a microwave hot melting chelation process by using the new metatitanic acid precipitate as a titanium source and citric acid as an acid solvent and chelant. The synthesized citricacide-titatnium chelate is high in purity, does not contain foreign ions such as chlorine ions or sulfur ions, is stable in performance, and can be placed for a long time; titanium gel precipitate is not separated out after the citricacide-titatnium chelate is diluted; and the citricacide-titatnium chelate can be compounded with multiple kinds to metal ions and organic matter, can be reacted with peroxide to form titanium peroxide complex, and can also be compounded into various functional materials. A process is simple and is easy to control.

Description

Technical field [0001] The present invention is a new technology prepared by titanium citrate. It specifically involves new precipitated polar acid that is not contained in chlorine and sulfur ions and can dissolve in citric acid as the source of titanium.New methods of titanium citrate without chlorine and sulfur ions with chelating reactions. Background technique [0002] Titanium citric acid has a wide range of application prospects, such as titanium citrate as a new type of crop growth regulator and functional micro -fertilizer. Titanium titanium titanium has been promoted; citrate titanium titanium titanium is not harmful, and toxic chromium tannants also replacedIt is promoted and applied; titanium titanium has also been proven to have drug effects to resist tumors. [0003] At the same time, titanium titanium is still preparing the front -drive body of titanium -based functional materials such as light catalytic self -cleaning materials, air purification materials, antibac...
