4.4: Conclusions and Review
The opportunity to use alternatives to typical organic solvents to do the same transformations with the same or better efficiencies has never been better than today. We are learning that we can do a lot of chemistry in a green way because we are putting our efforts into it. Although we still have a long way to go before solventless, gas phase, etc., are the mode of doing chemistry, the range of available reactions and processes is superb.
Review Questions
- What are the implications of using alternative solvents from a life cycle analysis perspective?
- What are the energetic considerations for allowing polymerization to occur by ball milling?
- What is the difference between a “critical point” and the “triple point” as defined in standard phase diagrams?
