Synthesis industrial uses

G.K., Diner, B.A. et al. (2014) Recombinant anaerobic acetogenic bacteria for production of isoprene and/or industrial bio-products using synthesis gas. US Patent 2014/0234926 Al. 

The above synthesis, although performed on a small scale, is easily scaled up to industrial size (French Pat. 2,669,922, CA 118 P6734U). It is a general procedure for substituting aryl-Br with -OMe or -OEt, giving us the possibility to produce other compounds from already known substances, e.g bromination of MDA yields 6-Br-MDA. This is converted by the above procedure to MMDA-2, 133, active at 25-50mg, 8-12 hrs.

We have been fully occupied by our explorations. There has been no attempt as yet, in our laboratories or in others , to apply the chemistry to the synthesis of natural products or pharmaceuticals there has been no attempt to utilize the chemistry for industrial requirements, nor has there yet been any systematic effort to develop the physical organic aspects of this area. All that is still before us. Another major task before us is that of educating students in the experimental methods and techniques of this area of chemistry so that they will not hesitate to apply these fascinating new methods. Clearly we have uncovered a new continent, only partially explored. It will require a major effort on the part of many chemists to continue the exploration and to apply the chemistry for the benefit of mankind. 

Industrial applications of zeolites cover a broad range of technological processes from oil upgrading, via petrochemical transformations up to synthesis of fine chemicals [1,2]. These processes clearly benefit from zeolite well-defined microporous structures providing a possibility of reaction control via shape selectivity [3,4] and acidity [5]. Catalytic reactions, namely transformations of aromatic hydrocarbons via alkylation, isomerization, disproportionation and transalkylation [2], are not only of industrial importance but can also be used to assess the structural features of zeolites [6] especially when combined with the investigation of their acidic properties [7]. A high diversity of zeolitic structures provides us with the opportunity to correlate the acidity, activity and selectivity of different structural types of zeolites. 

The Cinchona tree remains the only economically practical source of quinine. Although the development of synthetic quinine is considered a milestone in organic chemistry, it has never been produced industrially as a substitute for naturally occurring quinine. Nevertheless, the implications of the total synthesis of quinine in new strategies for the development of safer and more efficient antimalarial drugs, as we will show in the course of the next paragraphs, is priceless. But, let us discuss this total synthesis first. 

In this book we have tried to assemble a selection of authors to shine light on the underlying principles of microwave dielectric heating, how this dielectric heating has been used in chemistry to give us microwave-assisted organic synthesis applied on a wide variety of reaction types as well as on how microwave-assisted organic synthesis has impacted the chemistry research within industry. 

Chemical kinetics is a subject of crucial environmental and economic importance. In the upper atmosphere, for example, maintenance or depletion of the ozone layer, which protects us from the sun s harmful ultraviolet radiation, depends on the relative rates of reactions that produce and destroy O3 molecules. In the chemical industry, the profitability of the process for the synthesis of ammonia, which is used as a fertilizer, depends on the rate at which gaseous N2 and H2 can be converted to NH3.
