Until here we have presented how R-SPL can represent molecular reaction schemas. However, as the name "processStep" implies, the original design purpose of this feature was really describing chemical (pharmaceutical) processing steps that reduce the reaction from a general idea into the practice of synthetic chemistry. The realization here is that a reaction ultimately can be performed by adding enough practical details so that the reaction can be performed. Such details are determining suitable solvents and catalysts, reaction conditions (temperature, pressure), as well as preparatory steps and work-up steps. The schematic reaction will still be there in principle, but other steps and conditions will now be added.
