Embodiment 1

[0021] Accurately weigh 1 mole of lanthanum carbonate (the amount of contained water of crystallization can be accurately determined by EDTA titration), and weigh 6 moles of gluconic acid. Add a small amount of water to stir the lanthanum carbonate into a paste, make a saturated aqueous solution of gluconic acid and add it to the lanthanum carbonate paste. Place the reactor on a constant temperature magnetic stirrer at 40°C and react while stirring. During the reaction, the lanthanum carbonate was continuously dissolved, accompanied by the release of carbon dioxide bubbles. When the carbon dioxide bubbles stopped escaping (at this time, the reactor became a transparent aqueous solution), the reaction was continued for another 30 minutes to fully complete the reaction. Then, by evaporation and concentration, the target product is precipitated as a solid. Filter, dry naturally in the air to get the lanthanum gluconate solid complex to be synthesized, the chemical formula is La...

Embodiment 2

[0023] Accurately weigh 1 mole of lanthanum carbonate (the amount of contained crystal water can be accurately determined by EDTA titration) and 6 moles of gluconic acid. Add a small amount of water to stir the lanthanum carbonate into a paste, make a saturated solution with gluconic acid and add it to the lanthanum carbonate paste. Place the reactor on a constant temperature magnetic stirrer at 50°C and react while stirring. During the reaction, the lanthanum carbonate was continuously dissolved, accompanied by the release of carbon dioxide bubbles. When the carbon dioxide bubbles stopped escaping (at this moment, the interior of the reactor became a transparent aqueous solution), the reaction was continued for another 50 minutes to fully complete the reaction. Concentration by evaporation then precipitated the target product as a solid. Filter, dry naturally in the air to obtain the lanthanum gluconate solid complex to be synthesized, and its chemical formula is La(C 6 h ...

Embodiment 3

[0025] Accurately weigh 1 mole of lanthanum carbonate (the amount of contained crystal water can be accurately determined by EDTA titration) and 6 moles of gluconic acid. Add a small amount of water to stir the lanthanum carbonate into a paste, make a saturated solution with gluconic acid and add it to the lanthanum carbonate paste. Place the reactor on a constant temperature magnetic stirrer at 45°C and react while stirring. During the reaction, the lanthanum carbonate was continuously dissolved, accompanied by the release of carbon dioxide bubbles. When the carbon dioxide bubbles stopped escaping (at this moment, the interior of the reactor became a transparent aqueous solution), the reaction was continued for another 50 minutes to fully complete the reaction. Concentration by evaporation then precipitated the target product as a solid. Filter, dry under the infrared lamp to obtain the lanthanum gluconate solid complex to be synthesized, its chemical formula is La(C 6 h ...

Abstract

The chemical formula of said invented additive of fish bait is La(C6H11O7)3, where Ln=La, Ce, Pr, Nd and Sm; and its preparation method includes the following steps: adding water into rare earth carbonate, stirring to make it into paste material; dissolving gluconic acid in water to prepare saturated solution, then adding the aqueous solution of gluconic acid into the rare earth carbonate paste, stirring them under the condition of 40-50 deg.C, until it has no escaped bubble, continuously reacting for 30-50 min to obtain fuel reaction, then evaporating and concentrating to separate out product, filtering, natural drying in the air or drying under the infrared lamp so as to shorten drying time. Its product rare earth glucontate coordination compound yield can be up to 92.6-94.3%.

Description

technical field [0001] The invention belongs to fish bait additives, and in particular relates to a fish bait additive of gluconic acid rare earth complex and a preparation method thereof. Background technique [0002] The well-developed fish farming will provide our people with increasing animal protein, which will definitely improve the dietary structure of our people and improve their health. This is of great and far-reaching significance to the prosperity and long-term stability of the Chinese nation. The key to the development of fish farming is high-efficiency fish bait, but at present my country's feed industry is still very backward. Patent literature has reported some bait additive research results. For example, the antiseptic antioxidant of fish and shrimp feed (application number 90100533); make feed additive with compound amino acid (application number 89105175 and 91104189); ). However, the research and development of rare earth fish bait additives is only i...
