What is the preparation method of Piperazine-N, N - Bis (2 - Ethanesulfonic Acid), 1.5 Sodium
To prepare Piperazine - N, N - Bis (2 - Ethanesulfonic Acid), 1.5 Sodium (piperazine - N, N - bis (2 - ethanesulfonic acid) 1.5 sodium salt), the following methods can be used:
First, the raw materials need to be prepared. Piperazine is the key starting material, and 2 - chloroethanesulfonic acid or its suitable salts are required as sulfonic acid introduction reagents. At the same time, alkali substances such as sodium hydroxide are used to adjust the pH and promote the reaction during the reaction, and can promote the formation of sodium salts of the product.
To start the reaction, place an appropriate amount of piperazine in a suitable reaction vessel, and add an appropriate amount of solvent, such as polar organic solvents such as methanol, ethanol or a mixed system of water and organic solvents, to help the material disperse and the reaction proceed. Then, under stirring, slowly add 2-chloroethanesulfonic acid or its salts. This process should be controlled at temperature, which can be started at low temperature, and then moderately heated according to the reaction process, so that the reaction can occur smoothly. Generally speaking, the initial temperature can be set to 0-10 ° C, followed by heating to 30-50 ° C for continuous reaction.
During the reaction, with the help of a pH meter to monitor the pH of the system, a sodium hydroxide solution is added dropwise in a timely manner to maintain the reaction system in a suitable pH range, usually between 7 and 9, which is conducive to the forward progress of the reaction and the formation of products. The reaction lasts for a period of time, about 2 to 6 hours. During this period, regular sampling and monitoring are carried out. The reaction process and product formation are observed by means of thin layer chromatography (TLC) or high performance liquid chromatography (HPLC).
When the reaction reaches the desired level, that is, the reaction of the raw materials is complete or the proportion of the products reaches a satisfactory value, stop heating and stirring. Then, the reaction solution is cooled to room temperature, at which time solid may precipitate. If there is no precipitation, some of the solvent can be removed by vacuum distillation to promote the crystallization of the product. The resulting solid is collected by suction filtration and washed with an appropriate amount of cold solvent to remove impurities.
Finally, the obtained crude product is recrystallized and purified. Select a suitable solvent, such as ethanol-water mixed solvent, heat to dissolve the crude product, and filter it hot to remove insoluble impurities. The filtrate is slowly cooled to recrystallize the product and precipitate it. It is collected by suction filtration again and dried in vacuum at a suitable temperature to obtain the pure product of Piperazine - N, N - Bis (2 - Ethanesulfonic Acid), 1.5 Sodium.
