Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 2215-77-2, Name is 4-Phenoxybenzoic acid, SMILES is OC(=O)C1=CC=C(OC2=CC=CC=C2)C=C1, belongs to phthalazine compound. In a document, author is Shirini, Farhad, introduce the new discover, COA of Formula: https://www.ambeed.com/products/2215-77-2.html.
This article describe the applicability of 1,4-disulfopiperazine-1,4-diium chloride ([Piper-(SO3H)(2)].2Cl) as a green, versatile and Bronsted acidic ionic catalyst in the promotion of the synthesis of phthalazine derivatives via one-pot three component reaction between aromatic aldehydes, 1,3-diketone derivatives and phthalhydrazide under solvent-free reaction conditions. The main advantages of this method are: (1) simplicity of the procedure, (2) solvent-free conditions, (3) availability of the starting materials, (4) high reaction rates and excellent yields, (5) reusability of the catalyst and (6) no column chromatographic of the products.
