what are the changes that have taken place all this years? What are the reasons behind these changes? Is there common ground among the various reasons?

click search on the top of the forum. It has been discussed before.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

i believe the driving force for change over many industrial processes has been:
1. availability of raw materials
2. economics (lower operational cost, cheaper equipment & raw material)
2. safety (less hazardous process, safer operating conditions)
3. environmental concern (no toxic byproduct, or reduced toxic discharge)
4. technology (faster process, use cheaper catalyst)
