Electric Literature of 125995-03-1, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 125995-03-1, Name is Atorvastatin lactone, molecular formula is C33H33FN2O4. In a Patent，once mentioned of 125995-03-1
Process for the preparation of amorphous atorvastatin calcium
A process for the preparation of amorphous atorvastatin calcium and hydrates thereof, which comprises: (a) hydrolysis of the precursor lactone using sodium hydroxide to form atorvastatin sodium salt solution; (b) addition of the atorvastatin sodium salt solution to a calcium chloride or calcium acetate solution in the absence or presence of seeds of amorphous atorvastatin calcium; and (c) isolation of the resultant amorphous atorvastatin calcium salt by filtration and drying.
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 125995-03-1 is helpful to your research., Electric Literature of 125995-03-1
