Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 81-48-1, Name is 1-Hydroxy-4-(p-tolylamino)anthracene-9,10-dione, SMILES is O=C(C1=C2C=CC=C1)C3=C(NC4=CC=C(C)C=C4)C=CC(O)=C3C2=O, belongs to phthalazine compound. In a document, author is Mousapour, Maryam, introduce the new discover, COA of Formula: https://www.ambeed.com/products/81-48-1.html.
In this work, poly(vinylpyrrolidonium) perchlorate {[PVPH]ClO4}, a newly reported modified polymeric catalyst, is used as an efficient and reusable solid acid catalyst for the promotion of the synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives. All reactions were performed under mild conditions and the products were formed over short reaction times in excellent yields. It is important to note that this solid acid catalyst can be reused several times without any appreciable loss in its activity.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 81-48-1 is helpful to your research. COA of Formula: https://www.ambeed.com/products/81-48-1.html.
