Green chemistry or Sustainable chemistry is defined as the invention, design, development and application of chemical products and processes to reduce or eliminate the use and production of substances harmful to human health and the environment. Experiments should use alternative reagents that are not only environmentally friendly but also readily available nationwide in large quantities at very reasonable prices. Avoid using organic solvents (ether, petroleum ether, ethyl acetate, etc.) if possible. Ethanol and methanol are most preferred.
