Embodiment 1

[0051] (1) Preparation of metatitanic acid:

[0052]a. Add 1000ml of ice water at 0°C~5°C to a 1500ml beaker, and add 10ml of hydrochloric acid and 20ml of titanium tetrachloride dropwise under the stirring of an electric stirrer to generate a titanium tetrachloride hydrochloric acid solution. The sodium hydroxide solution neutralizes the titanium tetrachloride hydrochloric acid solution, the temperature of the solution is controlled at ≤5°C, and the pH value is 7.0~8.0, so that metatitanic acid is precipitated in cold water at ≤5°C;

[0053] b. The newly precipitated metatitanic acid is washed with distilled water to remove chloride ions,

[0054] c. After the metatitanic acid that has been washed to remove chloride ions is removed by a centrifuge to remove part of the adsorbed water, it can be used for acid-soluble chelation.

Abstract

The invention relates to a method for preparing an organic titanium-containing ammonium borate fertilizer with a recrystallization technology. The method is characterized by: using alkali to neutralize the ice water solution of a titanium salt so as to prepare a new precipitate metatitanic acid; using the new precipitate metatitanic acid to substitute a chloride of titanium and a sulfate to serve as the raw material for synthesizing titanium citrate; taking the new precipitate metatitanic acid as a titanium source, and citric acid as a solvent and a chelating agent, employing a micro wave hot melting and chelating process to synthesize a saturated titanium citrate solution; conducting neutralization and salting-out on the saturated titanium citrate solution with powdered ammonium carbonate for preparing a composite salt of organic titanium-organic ammonium, mixing the powder of the organic titanium-organic ammonium composite salt with crystal water-containing ammonium tetraborate and carrying out eutectic melting so as to manufacturing the titanium-containing ammonium borate fertilizer. Due to the characteristic of titanium element to powerfully promote the absorption and running of nitrogen, phosphorus, potassium as well as other secondary elements and trace elements in plants, water soluble titanium citrate with superior stability obtained from micro wave hot melting and sufficient chelating can be used as a synergist for promoting ammonium borate fertilizer absorption and a crop growth accelerator.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a method for manufacturing organic titanium-containing ammonium borate fertilizer composed of organic titanium and ammonium borate salt. Background technique [0002] Boron is one of the seven micronutrient elements necessary for plant growth and development. It plays an irreplaceable physiological role in the process of plant growth and development, and participates in many important physiological activities of plants. [0003] Boron deficiency in the soil of cultivated land, orchards, and woodlands in China is relatively common. According to the statistics of the second national soil census from 1982 to 1986, the area of ​​boron-deficient cultivated land in the country is more than 500 million mu. The proportion of boron deficiency in cultivated land in Guizhou, Sichuan, Hubei, Hunan, Anhui, Jiangsu, Jiangxi, Yunnan, Henan, Shaanxi, Guangdong, Fujian, Guangxi, J...
