Chemistry has a central role in science, and synthesis has a central role in chemistry. The synthetic chemists should focus their efforts to merge it with other fields to produce more interdisciplinary science. Chemical synthesis has now reached an extraordinary level of sophistication, but there is vast room for improvement. The 3Rs (reduction, recycling and reuse) of resources are particularl...

The term green chemistry is defined as “the invention, design and application of chemical products and processes to reduce or to eliminate the use and generation of hazardous substances”. The major applications of green chemistry principles and practice renders control, regulation, and remediation, hence resultant environmental benefit can be expressed in terms of economic impact .It also invol...

Chemistry has a key role to play in maintaining and improving our quality of life, such as in medicine, materials and electronics. However, it has also caused damage to human health and the natural environment. To make chemistry compatible with human health and the environ‐ ment, Anastas and Warner have proposed 12 principles of green chemistry, which help to explain what it means in practice [...

(3Z)-Hexenol, which is commonly called leaf al­ cohol, and (2£)-hexenal, also called leaf aldehyde, are widely distributed in fresh leaves, vegetables and fruits. They are mainly responsible for the socalled “green odour” characteristic of leaves, along with other C6-compounds such as (3£")-, and (2£)-hexenols, their corresponding aldehydes (3Z)-, (3£")-hexenals, «-hexanol and «-hexanal. Thus, ...

R ecent years have seen a disheartening string of revelations in which everyday items once considered safe—food packaging, toys, clothes, furniture, electronic components, and many more products—are found to contain carcinogens, endocrine disruptors, and other harmful chemicals. Growing demand for healthier alternatives, already seen in food production and housing construction, is also happenin...

Green chemistry is a tool, which when implemented right, can help the industry achieve its environmental goals. Broadly defined as the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances, green chemis t ry a l lows companies to develop better products through sustainable processes. In this article, we will summarize the dr ivers towa...
