Reactive Precipitation of Procaine Benzylpenicillin
procaine benzylpenicillin reactive precipitation secondary processes
2009/3/25
The reactive precipitation process of procaine benzylpenicillin is reviewed, while suchsecondary processes as ageing, agglomeration, breakage, and the effects of operationparameters oncrystal size a...
A simple extension of cubic equations of state (EOS) to polymer systems has been proposed. The So-ave-Redlich-Kwong (SRK) EOS was taken as a prototype to be used to describe the PVT behavior of polym...
