What is the synthesis method of Benzenesulfonicacid, 4,4 '-Oxybis-, Bis [2- (Aminocarbonyl) Hydrazide] (9Ci)?
To prepare benzene sulfonic acid, 4,4 '-oxobis-, bis [2- (aminocarbonyl) hydrazine] (9CI), the method is as follows:
First take an appropriate amount of starting materials, this raw material needs to be carefully selected to ensure purity and quality. Benzene is often used as the base, and it interacts ingeniously with sulfuric acid and other reagents to initiate a sulfonation reaction. In the reactor, control its temperature, pressure and reaction time. The temperature should not be too high to avoid side reactions; the pressure also needs to be adapted to help the reaction proceed smoothly. The control of time is related to the yield and purity of the product, and it needs to be precisely pinched.
When the benzene ring is successfully introduced into the sulfonic acid group, the benzene sulfonic acid intermediate is obtained. Then, for this intermediate, the structure of 4,4 '-oxobis is carefully introduced. This process requires the selection of suitable reagents and reaction conditions, or the use of condensation reactions, etc., to extend the molecular structure as expected.
The product is further converted and a group containing amino carbonyl hydrazine is added. This step requires clever design of the reaction path, or the use of a specific catalyst, to induce acylation or other suitable reactions, so that the bis [2- (aminocarbonyl) hydrazine] is successfully bonded to the target molecule.
The entire synthesis process requires careful monitoring of each step of the reaction, and analysis methods such as chromatography and spectroscopy are used to gain insight into the reaction process and product characteristics. Each step is carefully handled to prevent impurities from mixing in and affecting the purity and quality of the product. In this way, after many efforts and fine regulation, the target product benzenesulfonic acid, 4,4 '-oxobis-, bis [2- (aminocarbonyl) hydrazine] (9CI) can be obtained.
