One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 21905-86-2, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 21905-86-2, name is C9H6N2O2. In an article£¬Which mentioned a new discovery about 21905-86-2
1-(Ethoxycarbonyl)ethyl Cinnoline-4-carboxylate (32) A solution of 0.75 ml of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in 20 ml of benzene was added to a stirred suspension of 0.87 g of 1 in 30 ml of benzene at room temperature. After one hour of stirring, 1.36 g of ethyl 2-bromopropionate was added and the mixture was heated at reflux for 6 hours. The mixture was cooled, diluted with 25 ml of benzene, washed with water, 1 N aqueous sodium bicarbonate, and brine. It then was dried (MgSO4), the solvent was evaporated and the residue was chromatographed on silica gel, using a 1:1 v:v mixture of cyclohexane and ethyl acetate as eluent, to give 32, as a yellow oil.
