Amino phthalhydrazide was synthesized from phthalic anhydride by four steps of nitrationidehydration, hydrazinolysis and reduction reactions in this paper.
The water-soluble tripolymer of maleic anhydride(MA), sodium allylsufonate(SAS)and acrylamide(AM) was prepared with water as solvent and persulfate as initiator.
The diisoamyl glutarate in catalysis of silicotungsticacid was preparated by esterification of isoamyl alcohol and glutaric anhydride seperated from dicarboxylic acid.
The mechanical property and thermal stability of cured epoxy resin were closely related to the chemical structure of hydrogenated terpinene maleic anhydride.
Perioperative serum creatinine, electrolytes, blood gas, and a follow-up excretory urogram, cystogram, and pathological examination were used to assess the surgical outcome.
From rosin purified abietic acid was prepared by using abietic acid as stared material acylamino surfactant was synthesized by maleric anhydride and diethanolamine.
In the presence of catalyst phosphoric acid,isomeric addition of bipentene with cis-butenedioic anhydride can form terpenyl bu tenedioic anhydride compound as expoxylite firming agent.
In the presence of acetic acid and polyethylene glycol, chromic anhydride and acenaphthene react under mild condition and acenaphthene can completely convert into acenaphthenone.
The enzyme carbonic anhydrase catalyzes this reaction in the red blood cells, where carbon dioxide and water are converted into bicarbonate and hydrogen ion.
In our bodies, these kinds of reactions can’t and don’t take thousands of years to happen, because we have an enzyme called carbonic anhydrase that catalyzes that reaction.
