In many cases, addition or removal of water proceeds sufficiently slowly that some of the physical properties of unstable species (such as hydrated neutral quinazoline or anhydrous 2-hydroxypteridine) can be observed. In these cases, reaction kinetics can also be examined. Addition of water to pteridine is of special interest in relation to studies of the formation and hydrolysis of Schiflf bases. The reaction proceeds in two reversible stages, 3 4 5 ... 

There have been several kinetic studies of the calcination of dolomite [29], a reaction of considerable technological importance. As in many reversible reactions, the rate of carbon dioxide release is sensitive to the prevailing pressure of this product (.Pco2) in the vicinity of the reaction interfaces. At low pressures (PCo2 < 12 Torr), reaction proceeds to completion in a single stage between 900 and 950 K... 

The reaction was shown to follow step-growth kinetics in its early stages and to stop abruptly at the length defined by the template. No products were detected in the absence of any template. As the hydrogen bonding between the nucleobases and the imine formation are reversible, error correction occurs to some extent in this system. In this sense, this report matches the spirit of DCC more closely than many others. Unfortunately, no follow-up using the entire nucleic acid alphabet has been published hitherto.
