Green chemistry is an area of chemistry focused on designing chemical products and processes that minimize environmental impact and hazardous waste. It aims to prevent pollution at the molecular level through principles like maximizing atom economy in reactions and using renewable, non-toxic reagents. The field emerged in the 1990s in response to problems of chemical pollution and depletion, and seeks to promote sustainability through innovative chemical engineering approaches. Adoption of green chemistry helps protect nature and reduce use of precious resources.
With mounting concerns over the state of our planet, there is continuing demand that chemists
and chemical engineers should develop greener chemical processes and products. In the 1990s, with the
growing awareness of the hazardous impacts of the chemical industry, the green chemistry revolution was
launched by American chemists Paul T. Anastas and John Warner. Green chemistry is the kind of chemistry that
seeks to minimize pollution, conserve energy, and promote environmentally friendly production. This paper
provides a brief introduction to green chemistry.

It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

1. Introduction of green chemistry
This article is about the concept of the environmentally friendly design of chemical
products and processes.
Green chemistry, also called of products sustainable chemistry is an area of chemistry
and chemical engineering focused on the design and processes that minimize or
eliminate the use and generation of hazardous substances. environmental
chemistry focuses on the effects of polluting chemicals on nature, green chemistry
focuses on the environmental impact of chemistry, including lowering consumption of
nonrenewable resources and technological approaches for preventing pollution.
2. Definition of green chemistry
Green chemistry is the design of chemical products and processes that reduce or eliminate
the use or generation of hazardous substances.
Green chemistry applies across the life cycle of a chemical product, including its design,
manufacture, use, and ultimate disposal.
•Prevents pollution at the molecular level
•Is a philosophy that applies to all areas of chemistry, not a single discipline of chemistry
3. History-Green chemistry emerged from a variety of existing ideas and research efforts (such as atom
economy and catalysis) in the period leading up to the 1990s, in the context of increasing attention to problems
of chemical pollution and resource depletion. The development of green chemistry in Europe and the United
States was linked to a shift in environmental problem-solving strategies: a movement from command and
control regulation and mandated lowering of industrial emissions at the "end of the pipe," toward the active
prevention of pollution through the innovative design of production technologies themselves. The set of
concepts now recognized as green chemistry coalesced in the mid- to late-1990s, along with broader adoption
of the term (which prevailed over competing terms such as "clean" and "sustainable" chemistry).
4.
5. The twelve principles of green chemistry are:
1.Prevention. Preventing waste is better than treating or cleaning up waste after it is created.
2.Atom economy. Synthetic methods should try to maximize the incorporation of all materials used in the
process into the final product. This means that less waste will be generated as a result.
3.Less hazardous chemical syntheses. Synthetic methods should avoid using or generating substances
toxic to humans and/or the environment.
4.Designing safer chemicals. Chemical products should be designed to achieve their desired function
while being as non-toxic as possible.
5.Safer solvents and auxiliaries. Auxiliary substances should be avoided wherever possible, and as non-
hazardous as possible when they must be used.
6.Design for energy efficiency. Energy requirements should be minimized, and processes should be
conducted at ambient temperature and pressure whenever possible.
6. 7. use of renewable feedstocks. Whenever it is practical to do so, renewable feedstocks or raw materials are
preferable to non-renewable ones.
8.reduce derivatives. Unnecessary generation of derivatives—such as the use of protecting groups—should be
minimized or avoided if possible; such steps require additional reagents and may generate additional waste.
9 .catalysis. Catalytic reagents that can be used in small quantities to repeat a reaction are superior
to stoichiometric reagents (ones that are consumed in a reaction).
10.Design for degradation. Chemical products should be designed so that they do not pollute the environment;
when their function is complete, they should break down into non-harmful products.
11 .Deal-time analysis for pollution prevention. Analytical methodologies need to be further developed to permit
real-time, in-process monitoring and control before hazardous substances form.
12.Inherently safer chemistry for accident prevention. Whenever possible, the substances in a process, and the
forms of those substances, should be chosen to minimize risks such as explosions, fires, and accidental releases.
7. Green Chemistry: Whenever we think about the ‘Green’ color, the first thing
that comes into our mind is our beautiful environment which is full of natural
beauty! But nowadays as science and technology have progressed, the level of
pollution is on the rise. Scientists have thus discovered a new field in Chemistry
known as Green Chemistry.
Green Chemistry is also called “Sustainable Chemistry”. This branch of
Chemistry is used for designing chemical products and methods that reduce
hazardous chemical substances from being generated. This would help us to
design an efficient planet in which all living creatures can co-depend on each
other to benefit themselves.
8. Green chemistry metrics
describe aspects of a chemical process relating to the principles of green chemistry.
The metrics serve to quantify the efficiency or environmental performance of chemical
processes, and allow changes in performance to be measured. The motivation for
using metrics is the expectation that quantifying technical and environmental
improvements can make the benefits of new technologies more tangible, perceptible,
or understandable. This, in turn, is likely to aid the communication of research and
potentially facilitate the wider adoption of green chemistry technologies in industry.
