Textbook Question
Chapter 1.15, Problem 43P
Caffeine is a natural insecticide found in the seeds and leaves of certain plants, where it kills insects that feed on the plant. Caffeine is extracted for human consumption from beans of the coffee plant, from Kola nuts, and from the leaves of tea plants. Because it stimulates the central nervous system, it temporarily prevents drowsiness. Add caffeine’s missing lone pairs to its structure.

- According to open access forums ionic antimony Sb (111) can be reduced to elemental Sb (0) in solution and in macromolecules like condensation polymers polyethylene terephthalate (PET) causing greying of the polymer matrix. It has been connected to thermal degradation of the polymer during processing to the formation of thermally unstable EG ethyleen glycol that forms at various temperatures formic acid, formaldehyde, acetaldehyde and much more depending on temperature. I need to know what organics are more powerful reducing agents and at what concentration (relative) to each organic will initiate this reduction. Furthermore, is the pH dependant ? Are other trace elements in the plastic also a cause of concern e.g. aluminum from aluminum chloride (lewis acid). Therefore, the ultimate solution should include a means to inhibit reduction of ionic antimony and will the same solution comply with cobalt impurities from ionic cobalt? Some PET have combinations of catalyst and their residues…arrow_forwardFrom a pH standpoint is the reduction of ionic Antimony Sb (111) to elemental Sb (0) occur more readily by acidic species acting as reducing agents or basic substances?
