[0049] (1) Preparation of metatitanic acid:

[0050] a. Add 1000ml of ice water at 0℃~5℃ in a 1500ml beaker, and add 10ml hydrochloric acid and 20ml titanium tetrachloride dropwise under the stirring of an electric stirrer to generate a titanium tetrachloride hydrochloric acid solution. Use 10% The sodium hydroxide solution neutralizes the titanium tetrachloride hydrochloric acid solution, and the temperature of the solution is controlled to be ≤5℃ and the pH value is 7.0~8.0, so that the metatitanic acid precipitates out in cold water of ≤5℃.

Abstract

The invention relates to a method for preparing urea peroxide containing organic titanium by a recrystallization process. The method is characterized in that: new metatitanic acid precipitate of citric acid is prepared by neutralizing an iced solution of titanium salt by using alkali; the new metatitanic acid precipitate instead of titanium chloride and sulfate is used as raw materials for synthesizing citricacide-titatnium chelate; the citricacide-titatnium chelate is synthesized by a microwave hot melting chelation process by using the new metatitanic acid precipitate of citric acid as a titanium source and citric acid as an acid solvent and chelant; and the novel urea peroxide fertilizer containing the organic titanium is prepared by the steps of uniformly mixing hydrogen peroxide, acid citricacide-titatnium chelate and urea in a ratio, performing addition reaction on a mixture at the constant temperature of 60 DEG C, and recrystallizing at the temperature of less than or equal to 5 DEG C. The titanium element can strongly promote plant to absorb and convey nitrogen, phosphorus, potassium, other secondary elements and trace elements; the citricacide-titatnium chelate is reacted with hydrogen peroxide easily to form a titanium peroxide compound with high stability; and the citricacide-titatnium chelate can be used as stabilizer of urea peroxide, and synergist of urea peroxide nitrogenous fertilizer.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a method for urea peroxide containing organic titanium. Background technique [0002] Urea peroxide, also known as urea hydrogen peroxide, carbamide peroxide, carbamide peroxide, urea hydrogen peroxide, etc., is an adduct of urea and hydrogen peroxide, which has the properties of both urea and hydrogen peroxide. [0003] Urea peroxide is an efficient, multifunctional, broad-spectrum, safe, and easy-to-use green solid disinfectant, and it is also an excellent oxidant and active oxygen provider. [0004] Urea peroxide is also widely used in agricultural production. Urea peroxide is an excellent soil improver, an in-situ repair agent for soil organic pollution, and an oxygen-supplying fertilizer for aquatic crops such as rice and crop seeds to germinate. At the same time, Urea peroxide can also be used as an oxygen-enriched ripening agent and fresh-keeping agent for...
