About

GreenChemBlog is operated by a group of current and former UC Berkeley chemistry graduate students. Our aim is to provide a critical review of the latest Green Chemistry literature, while providing a forum where current issues including materials, toxicology and synthesis can be discussed by the community.

Any questions or suggestions can be sent to us at greenchemblog (at) gmail (dot) com.

  1. Are classes offered online for green chemistry?

    It would be great if they were.

  2. I like to view Green chemistry as a continuum, bounded by the principles of Green Chemistry and economics. As an industrial pharmaceutical process chemist, I was tasked with optimizing and scaling up chemical reactions. With each iteration, this questions is always asked:

    Is it better than the previous version?
    Meaning more efficient, higher yielding,
    less toxic raw materials (or at least hazards dealt with and contained), more robust and reproducible,
    similar or improved impurity profile
    comparable in cost or cheaper
    not dependent upon a critical technology or raw material
    reduction in solvents and/or processing aspects.
    replacement of “problematic” solvents
    less hazardous waste (or at least dealt with),
    opportunities for continuous operation, etc

    The weighting each of these areas receives depends on the needs of the chemistry and the company involved. When there isn’t a previous iteration, I think a contender for a “green” accolade needs to compare their whole process (solvents, etc) to prior art. Favorable comparisons are what gets people to use those new technologies and reactions.

    We sometimes forget that Green doesn’t have to mean just “wow” chemistry. It includes everything that can be done to improve the sustainability of a process. This includes energy savings from reduced processing times, etc. And above it all, it has to be practical and cost-effective or it will not compete with existing “non-green” technologies. By this token, an awful lot of “green” chemistry has and continues to be done outside the scope of traditional Green blogs.

  3. Thanks for your thoughts, Eric. I am in complete agreement about the need for green chemistry to be practical, and that a lot of green chemistry is not marketed that way. I also agree that the goals of process chemistry are pretty closely aligned with the goals of green chemistry, especially with respect to improving existing processes – for that reason we’ve included OPRD on our list of green chemistry journals and we’ve written a handful of posts on papers published by industrial labs.
    Thanks again for stopping by!
