Embodiment 1

[0033] Weigh 2.05g of 2-bromoethylamine hydrobromide and 1.59g of hexamethoxyquinoline and add them to a 50mL round-bottomed flask with a reflux condenser device, then add 2mL of ethanol and 10mL of acetonitrile to the round-bottomed flask, and mix The solution was heated to reflux at 80 degrees Celsius in an oil bath, and the reaction was detected by TLC until the raw material hexamethoxyquinoline no longer reacted. After the reaction was completed, the solvent ethanol and acetonitrile were removed by rotary evaporation under reduced pressure, and then an equal amount of the crude product was put into two 10mL centrifuge tubes, 6mL of ethanol was added to each, and centrifuged at 10000r for ten minutes until TLC detected that the supernatant contained no As far as the raw material hexamethoxyquinoline is concerned, the product washed with ethanol is dried in a vacuum drying oven at 60 degrees Celsius to obtain the pure product N-ethylamino-6-methoxyquinoline. Yield 92%.

Abstract

The invention relates to a synthesis method of a fluorescent molecular probe for detecting chlorine ions and application of the probe in detecting the chlorine ions in various actual water samples. The probe (N-ethylamino-6-methoxyquinoline) is synthesized by using a simple and low-cost method, and the probe is stable in property, high in specificity and sensitivity, short in response time, easy to prepare, low in cost and low in detection limit for measuring chlorine ions. By using the probe to detect content of chlorine ions in actual water samples, chlorine ion content in the actual water samples can be measured through fluorescence spectroscopy, and acquired results are slightly different from those acquired by a standard measuring method, so that N-ethylamino-6-methoxyquinoline has capability of quickly and conveniently detecting chlorine ions.

Description

technical field [0001] The invention relates to the synthesis of a fluorescent molecular probe N-ethylamino-6-methoxyquinoline and the detection of chloride ions, belonging to the field of organic light-emitting materials. Background technique [0002] Chloride ion content is an important indicator of water quality monitoring. Many ships in the navy are powered by steam, so they have high requirements for boiler water quality, and the monitoring of water quality indicators is very strict. Poor water quality will cause fouling, corrosion, and steam pollution of the steam power plant, which will directly affect the normal operation and service life of the steam power plant, and affect the safety and combat effectiveness of the ship. In order to ensure the normal operation of the steam power plant, it is an important task in the ship management to treat the water correctly and fully grasp the water quality. In addition, more importantly, Cl - It is the most abundant and impo...
