Problems solved by technology

When using spectrophotometry to detect hexamethylenediamine, parameters such as the amount of chromogenic agent, color developing temperature, and color developing time have a great influence on the detection results. The detection process is relatively complicated, the time is long, and the detection cost is high.
In addition, more importantly, the detection of hexamethylenediamine by spectrophotometry is often interfered by other diamines such as ethylenediamine and decyldiamine, which has a certain impact on the single recognition of hexamethylenediamine, which is not conducive to the detection of hexamethylenediamine.

Embodiment 1

[0028] Weigh 2000 mg of dehydrocholic acid and 887 mg of N,N'-carbonyldiimidazole, dissolve in 100 mL of dry chloroform, and stir at 40°C for 8 hours. The reaction solution was lowered to room temperature, extracted three times with deionized water, the organic phase was taken, dried with anhydrous sodium sulfate, and spin-dried in vacuo to obtain imidazolyl dehydrocholic acid white powder.

[0029] figure 1 It is the mass spectrogram of imidazolyl dehydrocholic acid. The characteristic peak at 453.2 in the figure is the ion proton peak of hydrogenation of the target product. There are no miscellaneous peaks in the spectrum, which proves that the prepared imidazolyl dehydrocholic acid has a high purity.

[0030] Weigh 249mg of 3,3'-diaminodipropylamine and 1800mg of imidazolyl dehydrocholic acid, dissolve in 25mL of dry chloroform, and stir at 45°C for 15 hours. The reaction solution was lowered to room temperature, spin-dried in vacuo, recrystallized with 10 mL of dichlorome...

Abstract

The invention discloses a compound for detecting hexamethylenediamine, the chemical name of the compound is 3,3'-didehydrocholic acid-based dipropylaminobutyric acid, and the chemical formula is C58H85N3O11. When the compound of the present invention is added to the solution containing hexamethylenediamine, the solution will turn red, and the hexamethylenediamine can be quickly detected by visual observation, and can be used to identify hexamethylenediamine with single selectivity. Whether the sample contains hexamethylenediamine.

Description

technical field [0001] The invention relates to a compound for detection reagent, in particular to a compound for detection of hexamethylenediamine, and a preparation method of the compound. Background technique [0002] Hexamethylenediamine is soluble in water, N,N-dimethylformamide, ethanol, etc. It is mainly used to react with adipic acid to produce nylon 66, and react with sebacic acid to produce nylon 610. It is an important intermediate in synthetic fibers . In recent years, with the rapid development of the domestic nylon industry, in the process of nylon production such as concentration and polymerization, the discharge of hexamethylenediamine raw materials that have not been fully utilized is also increasing. [0003] Hexamethylenediamine is highly toxic to the human body and can cause changes in the human nervous system, vascular tone and hematopoietic function, and severe poisoning can be fatal. Hexamethylenediamine can invade and endanger human health through i...
