Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.21905-86-2, name is Cinnoline-4-carboxylic acid, below Introduce a new synthetic route as follows., 21905-86-2
EXAMPLE 2 Potassium Cinnoline-4-carboxylate (2) 5.10 g of (1) was added over 30 minutes to a vigorously stirred solution of 2.02 g of potassium carbonate in 25 ml of water, at room temperature. The resulting mixture was stirred for one hour at room temperature, then treated with charcoal, and after filtration the water was evaporated. The residue was azeotropically distilled with toluene and dried at 70 C. under reduced pressure, to give 2, as a light tan powder, m.p.: above 280 C.
In every case, we must determine the overall rate law from experimental data and deduce the mechanism from the rate law (and sometimes from other data). you can also browse my other articles about Cinnoline-4-carboxylic acid, CAS: 21905-86-2, if you are interested.
