What is the synthesis method of 4- (2 - Hydroxyethyl) -1-Piperazineethanesulfonic Acid, Disodium Salt?
The synthesis method of 4 - (2 - hydroxyethyl) -1 - piperazine ethane sulfonate disodium salt, which is detailed as follows.
First of all, the raw materials should be prepared, 2 - hydroxyethyl piperazine and appropriate sulfonating reagents should be used. Sulfonating reagents, such as 1,2 - dichloroethane sulfonic acid, should be selected carefully to meet the needs of the reaction.
In the reactor, pour an appropriate amount of 2 - hydroxyethyl piperazine, according to the number of moles, and add the sulfonating reagent in a precise way. Reaction temperature, when controlled at an appropriate value. Initially, it can be slowly heated to about 50 - 60 degrees Celsius, so that the two gradually interact. At this temperature, the molecular movement is appropriate, which is conducive to the initiation of the reaction and avoids the proliferation of side reactions.
As the reaction proceeds, the temperature can be gradually raised to 80-90 degrees Celsius to accelerate the reaction process. The reaction time is about time, and it needs to be measured by an instrument during this period to observe the degree of reaction.
After the reaction is completed, the temperature is cooled to room temperature. At this time, the reaction solution contains products and impurities. By means of neutralization, a sodium hydroxide solution can be slowly dripped in, and the pH is adjusted to alkaline, so that the product becomes a sodium salt state.
Then, the separation technique is performed. It can be extracted with an organic solvent to remove its oil-soluble impurities. Then by vacuum distillation, in addition to the solvent, the crude product is obtained.
The crude product is impure and needs to be refined. An appropriate solvent can be selected by recrystallization, such as ethanol-water mixed solvent. Dissolve the crude product in a hot solvent and filter it hot to remove its insoluble matter. After the filtrate is cooled, the product crystallizes out, filtered and dried to obtain a pure 4- (2-hydroxyethyl) -1 -piperazine ethane sulfonate disodium salt. The whole process, the operation should be careful, and the conditions should be strict, in order to obtain a good product.
How do 4- (2 - Hydroxyethyl) -1-Piperazineethanesulfonic Acid, Disodium Salt react with other compounds?
The disodium salt of 4- (2-hydroxyethyl) -1 -piperazine ethanesulfonate, often referred to as "HEPES disodium salt", has a wide range of uses in biochemical experiments. Its properties are relatively stable, and it will react when it encounters specific substances.
In contact with strong acids, the sulfonic acid group in HEPES disodium salt binds to protons, and the equilibrium shift, and the pH of the solution changes. In case of hydrochloric acid, the reaction is intense, and the degree of ionization is greatly changed, which affects the buffering performance.
In case of strong bases, the nitrogen atom on the hydroxyethyl group or piperazine ring can interact with the hydroxide group. Like sodium hydroxide, or dehydroxy of hydroxyethyl, affecting the molecular structure and function.
Metal ions such as copper ions and zinc ions can coordinate and complex with nitrogen and oxygen atoms in HEPES disodium salt, changing molecular properties, or reducing buffering capacity and interfering with experiments.
When encountering strong oxidants, the molecule contains oxidizable elements such as nitrogen and sulfur, or is oxidized, resulting in structural breakdown and dysfunction. In case of hydrogen peroxide, the sulfur oxidation state may rise and the molecular chemistry may be changed.
Organic halide, or nucleophilic substitution with HEPES disodium salt, the halogen atom is replaced with active hydrogen or other groups in the molecule, changing the chemical structure and properties.
Experimental HEPES disodium salt, be careful to pay attention to its possible reaction with other substances to prevent affecting the results, and ensure the accuracy and reliability of the experiment.
