New Trends in Green Chemistry by V.K. Ahluwalia

By V.K. Ahluwalia

Organic chemistry has performed a necessary function within the improvement of various molecules that are utilized in medicinal drugs, agrochemicals and polymers. such a lot ofthe chemical compounds are produced on an commercial scale. the commercial homes undertake a synthesis for a specific molecule which might be reasonably-priced. No consciousness is paid to prevent the discharge of destructive chemical substances within the surroundings, land and sea. in past times decade targeted emphasis has been made in the direction of eco-friendly synthesis which circumvents the above difficulties. Prof. V. okay. Ahluwalia and Dr. M. Kidwai have made a honest attempt during this course. This ebook discusses the fundamental rules of eco-friendly chemistry incorporating using eco-friendly reagents, eco-friendly catalysts, part move catalysis, eco-friendly synthesis utilizing microwaves, ultrasound and biocatalysis intimately. distinct emphasis is given to liquid section reactions and natural synthesis within the stable part. i need to congratulate either the authors for his or her pioneering efforts to write down this ebook. cautious number of numerous subject matters within the publication will serve the rightful objective for the chemistry neighborhood and the economic homes in any respect degrees. PROF. JAVED IQBAL, PhD, FNA exclusive study Scientist & Head Discovery learn Dr. Reddy's Laboratories Ltd.

Nuclear Magnetic Resonance: A Review of Chemical Literature: Vol 31 (Specialist Periodical Reports)

As a spectroscopic technique, Nuclear Magnetic Resonance (NMR) has noticeable staggering progress over the last twenty years, either as a strategy and in its functions. at the present time the purposes of NMR span quite a lot of clinical disciplines, from physics to biology to drugs. each one quantity of Nuclear Magnetic Resonance contains a mix of annual and biennial reviews which jointly offer entire of the literature in this subject.

d-Orbitals in the Chemistry of Silicon, Phosphorus and Sulfur

This publication used to be undertaken for the aim of bringing jointly the generally assorted strains of experimental paintings and pondering which has been expressed yet has frequently been unheard at the name query. it is going to be transparent to the reader severe point of view has been maintained in assembling the cloth of this speedily increasing quarter of outrage to natural chemists.

Example text

The toxicity ofthese compounds and their environmental consequences render these syntheses somewhat undesirable. Tundo 1•2 developed a method to methylate active methylene compounds selectively using dimethy1carbonate (DMC) (Scheme I) in which no inorganic salts are produced. R R Scheme 1 Dimethy1carbonate (DMC) can also act as an organic oxidant. Cyclopentanone and cyclohexanone react with DMC and a base ~C03 to yield adipic and pimelic methyl (or ethyl) esters, respectivelyl (Scheme 2). n= 1,2 Scheme 2 Many oxidative processes have negative environmental consequences.

3. 4. 5. 7. Green Catalysts Some of the major advances in chemistry especially industrial chemistry, over the past decade have been in the area of catalysts. Through the use of catalyst, chemists have found ways of removing the need for large quantities of reagents that would otherwise have been needed to carry out the transformations and ultimately would have contributed to the waste stream. Catalysts playa major role in establishing the economic strength of the chemical industry and the clean technology revolution in the industry will provide new opportunities for catalysis and catalytic processes.
