Textbook Problem

One of the winners of the 2016 Presidential Green Chemistry Challenge Awards was a process for making a high octane feedstock for gasoline. The traditional process uses highly corrosive acids such as hydrofluoric acid or sulfuric acid. Once used, the remaining acid must be regenerated or sent for disposal, requiring additional energy and generating waste. The new process uses a safer solid catalyst that can be regenerated and reused. It also leads to minimal by products. Which principles of green chemistry are being followed by this new process compared to the other process?

Interpretation Introduction


The principles of green chemistry that matches for new process compared to older process has to be given.

Concept Introduction:

Green chemistry:

The utilization of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and the application of chemical products.

The new procedure applies all of these principles either to a greater or lesser extent.

  • It is better to prevent waste than to treat or clean up waste after it is formed.
  • Synthetic methods should be designed to maximize the incorporation of all materials used in the final product.
  • Synthetic method should be designed to use and generate substances that possess little or no toxicity to human health or the environment.
  • Chemical products should be designed to function effectively while still reducing toxicity.
  • Synthetic methods should be conducted at ambient temperature and pressure.
  • Raw materials should be renewable whenever technically and economically practical.
  • Chemical products should be designed so that at the end of their function, they do not persist in the environmental or break down into dangerous products.
  • Substances used in a chemical process should be chosen to minimize the potential for chemical accidents, including releases, explosions, and fires.

The principle that is used in the new processes are,

  1. 1) Reducing the derivatives...
