Green Chemistry Innovations
Green chemistry, an area of study within organic chemistry, aims to design products and processes that reduce or eliminate hazardous substances. This field promotes sustainable practices and renewable resources in chemical production. One breakthrough is biodegradable plastics. Traditional plastics are derived from petroleum, a non-renewable resource, and can take centuries to decompose. Biodegradable plastics, made from renewable materials like corn starch, can break down in months under composting conditions, reducing pollution and landfill burden. Another advancement is the use of catalysis to increase reaction efficiency. Catalysts speed up chemical reactions without being consumed and can often replace hazardous chemicals. Researchers have developed metal-organic frameworks (MOFs) that serve as efficient catalysts in various organic reactions. For example, they can be applied in the process of degrading of pollutants into harmless compounds, which can aid in water and air purification. In addition to catalysts, green chemistry also studies solvents. A solvent is a liquid that dissolves other substances and provides a medium for these substances to react. For example, using water as a solvent instead of organic solvents, which are often toxic, creates safer and more sustainable processes. Additionally, reactions in water can sometimes proceed faster than in organic solvents.
The passage indicates that using water as a solvent is beneficial for all of the following reasons EXCEPT:
AIt can produce catalysts more safely.
BIt can reduce the need for toxic solvents.
CIt can result in more sustainable processes.
DIt can increase the speed of reactions.
