The rate constant hydrolysis of α-( p -nitrophenyl)cinnamonitrile(NCPN) and its derivatives have been determined at various pH, and the rate equation which can be applied over a wide pH range is obtained. On the basis of the rate equation, hydrolysis product, general base, and substituent...
Re: synthesis of dinitrile (mechanism) «Reply #2 on:March 02, 2009, 03:11:59 PM » 3->5 :I know the mechanism for a normal hydrolysis(HCl in this case) of acetal,but i dont know how it works for the ring.I also don't know what THF does in this mechanism. ...
Some new data were obtained about alkaline hydrolysis of a polyacrylonitrile (PAN) suspension at 75°C in a water/ethanol mixture. At >95% conversion of nitrile groups, the hydrolyzed polymer contains ≈20% of amidines situated in the nearest neighborhood of carboxylate groups. After complete hyd...
Hydrolysis is a type of chemical reaction where a water molecule adds to the starting hydrocarbon. In the case of nitriles, its hydrolysis takes place in two steps. The first step is the hydrolysis of the nitrile to an amide. The second step is the hydrolysis of the amide...

Nitrilases comprise a superfamily of thiol enzymes found in animals, plants, fungi and in certain prokaryotes23. They perform nitrile and amide hydrolysis and the N-acylation (reverse amidolysis) of proteins. The nitrilase reaction takes place in a globular domain with a conserved abba fold and ...

Click the Images to view 3D Mechanism The inner sphere mechanism shown diagrammatically above involves the joining of two complexes via a bridging ligand and the loss of another ligand to accommodate this steric change. This complex can then transfer electron density via the bridging ligand from on...
The floatability of PS, PC, and ABS reduces owing to the introduction of carbonyl (O = CO), hydroxyl (−OH), and amide (O = C–NH2) on plastic surfaces, which is the result of the oxidation by sulfate radical (SO4∙-) and the hydrolysis of nitrile group (CN) and ...
