2% 2C6 - Diethylamino - fluorescein potassium bromide (2,6 - Diethylamino - fluorescein potassium bromide) is a chemical preparation. The preparation method is as follows:
First take an appropriate amount of fluorescein and place it in a clean reaction vessel. This fluorescein needs to be of high quality and have few impurities to ensure a smooth subsequent reaction.
Then measure a certain amount of ethylamine and slowly inject it into the reaction vessel containing fluorescein. During this period, it is necessary to strictly control the amount of ethylamine, because the amount of ethylamine has a great impact on the purity and yield of the product. When injecting ethylamine, it should be slowly added dropwise, and gently stirred with a glass rod or a magnetic stirrer to promote the two to be fully mixed and evenly contacted.
After the addition of ethylamine, heat the reaction vessel in a water or oil bath at a specific temperature. Temperature control is crucial, and it is necessary to precisely adjust the appropriate temperature according to the characteristics and requirements of the reaction, usually around [X] ° C. During the heating period, continue to stir to facilitate the smooth and efficient progress of the reaction.
After the reaction has been cooled for a period of time, add an appropriate amount of potassium bromide to it. Potassium bromide also needs to be accurately weighed. It plays a unique role in the reaction and is related to the structure and properties of the final product. After adding potassium bromide, stir it again to fully participate in the reaction.
Subsequently, the reaction products are separated and purified by methods such as filtration, extraction, and crystallization. When filtering, filter paper or membrane with suitable pore size is selected to ensure that impurities are removed; during the extraction process, an appropriate extractant is selected to effectively separate the target product from the reaction mixture; during the crystallization stage, conditions such as temperature and solution concentration are adjusted to make the product precipitate in a pure crystal form.
Finally, after drying treatment, the residual moisture or solvent in the product is removed to obtain the finished product of 2,6-diethylaminofluorescein potassium bromide. The entire preparation process has strict requirements on the amount of raw materials, reaction temperature, time, and separation and purification steps. Careful and meticulous operation is required to obtain high-quality products.

2% 2C6 -diethylaniline hydrochloride is a chemical substance. When storing and transporting, be sure to pay attention to the following matters:
First, when storing, it should be placed in a cool, dry and well-ventilated place.
