Known Processes that Become Entirely Better or Otherwise Different

2 Known Processes that Become Entirely Better or Otherwise Different 

It is certainly more philosophical question as to whether a known process that becomes entirely better or otherwise different is to be called new or old with a new complexion. It is - chemically speaking - even more difficult when better or otherwise different refer to imdertaking a new elemental pathway, i.e. to following a different reaction mechanism. 

Some authors even speak of inaccessible regimes when processes are operated with maximum selectivity [110]. As pointed out above, there is no clear definition of what a new process regime is and what just a change of process parameters is. Hence the definitions given here may be taken as a guideline until there are better ones.
