Embodiment 1

[0030] The preparation of fluorescent ethylenediaminetetraacetic acid-ethylenediammonium salt, the steps are as follows:

[0031] 1) Dissolve 1g of ethylenediaminetetraacetic acid and 0.4109g of ethylenediamine in 5ml of distilled water, place it in a solution vacuum bottle under the protection of nitrogen, and oscillate ultrasonically for 10 minutes until all the raw materials are dissolved and become a colorless and transparent solution. After stirring at 30°C for 12 hours, the solution turned into a brown transparent liquid, and mixture Ⅰ was obtained;

[0032] 2) After the mixture I was washed three times with petroleum ether, water and petroleum ether were removed by rotary evaporation under reduced pressure to obtain a transparent solid, and a fluorescent ethylenediaminetetraacetic acid-ethylenediammonium salt was obtained.

Embodiment 2

[0039] The preparation of fluorescent ethylenediaminetetraacetic acid-ethylenediammonium carboxylate ammonium salt, the steps are as follows:

[0040] 1. Dissolve 1g of ethylenediaminetetraacetic acid and 0.4109g of ethylenediamine in 5ml of distilled water, place it in a solution vacuum bottle under the protection of nitrogen, and oscillate ultrasonically until the raw materials are completely dissolved and become a colorless and transparent solution. Place the device at 0 Stirring at ℃ for 36 hours, the solution turned into a brown transparent liquid, and mixture Ⅰ was obtained;

[0041] 2. After the mixture I was washed three times with petroleum ether, water and petroleum ether were removed by rotary evaporation under reduced pressure to obtain a transparent solid, and a fluorescent ammonium carboxylate was obtained.

[0042] The characterization of the product obtained is similar to Example 1.

Embodiment 3

[0044] The preparation of fluorescent ethylenediaminetetraacetic acid-ethylamine carboxylate ammonium salt, the steps are as follows:

[0045] 1. Dissolve 1g of ethylenediaminetetraacetic acid and 0.616g of ethylamine in 5ml of distilled water, place it in a solution vacuum bottle under the protection of nitrogen, and oscillate ultrasonically until all the raw materials are dissolved and become a colorless and transparent solution. Place the device at 30°C Stirring in the environment for 12h, the solution turned into a brown transparent liquid, and the mixture Ⅰ was obtained;

[0046] 2. After the mixture I was washed three times with petroleum ether, water and petroleum ether were removed by rotary evaporation under reduced pressure to obtain a transparent solid, and a fluorescent ammonium carboxylate was obtained.

[0047] Its fluorescent properties are similar to Example 1.

Abstract

The invention provides a preparation method of fluorescent ammonia carboxylate. The preparation method comprises the following steps of dissolving carboxylic acid and organic amine into distilled water, putting into a flask with a cork under the nitrogen protection condition, oscillating to dissolve by ultrasonic waves, stirring and reacting for 12-36h at the temperature of 0 to 30 DEG C, and obtaining a water solution with main ingredient of ammonia carboxylat mixture; washing the water solution with the ammonia carboxylat mixture for three times by petroleum ether, and performing water-phase pressure relief and rotary evaporation, so as to obtain the fluorescent ammonia carboxylate. The ammonia carboxylate prepared by the preparation method has the advantages that the preparation method is simple, the yield is high, the fluorescent property is excellent, the transmitting wavelength also changes along with the change of exciting wavelength, and the reliance of exciting wavelength is realized; the ferric ions can be well identified, and a linear relationship is formed between the concentration of ferric ions and the degrading of fluorescent intensity.

Description

technical field [0001] The invention relates to a method for preparing ammonium carboxylate salt with fluorescence by using carboxylic acid and organic amine as raw materials. Background technique [0002] At present, substances with fluorescence can be roughly divided into two types. One is because the molecule has a conjugated heterocyclic ring and various chromophores, by introducing unsaturated groups with fluorescent properties such as ethylenic bonds and benzene rings and various chromophores to change the conjugated length, so that the compound Photoelectric properties change. The other is a dendritic compound or supramolecular structure of amides, secondary or tertiary amines with atypical chromophores in the molecule. At present, there is no report of carboxylate ammonium salt with fluorescent properties without chromophore in its structure. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a metho...
