Chemistry, basic production

The present Volume deals with various aspects of bioactive natural products referring to 2,807 references. Everyone can agree that it is not at all easy to examine 2807 references in a short period. By reading this Volume, we can have access to these scientific treasures. Fourteen reviews in this Volume treat diverse and different topics in natural products chemistry - basic ones, medicinally oriented ones, agro-oriented ones, and ecologically oriented ones. They are all good introductions to the specific fields of bioactivities including a timely review on pheromones. 

This book is written primarily to engineering students in the fields of basic chemistiy, environmental chemistry, food production, chemical and biochemical engineering who in the begiiming of their university studies receive education in inorganic chemistry and applied chemistry in general.

Z.N. catalysts are the only ones able to polymerize C2H4 and C3H6, two basic products of petrochemistry, into (stereo) regular high M.W. polymers. That is an extremely important industrial achievement, as illustrated by the (approximate) data below which mean that, taking into account polydienes (see Part II) and a few experimental polymers, Z.N. catalysis alone is not responsible for a production of ca. 10 miUion tons a year of excellent products (obtained in one step from basic petrochemicals) that is a unique case in industrial organic chemistry, particularly if one considers the extreme diversification achieved in their apphcations. 

The basic Solvay process remains the dominant production route for soda ash. Its continued success is based on the raw matedals, salt and limestone, being more readily available than natural alkaU. AH soda ash processes are based on the manipulation of saline phase chemistry (6,7) an understanding of which is important both to improving current processes and to the economic development of new alkaU resources. 

RTV Silicone Chemistry. There are two basic cure chemistries used by RTV sihcones the acetoxy-based and the alkoxy-based cure systems. Acetoxy-based RTV sihcones were first commercialized in the early 1960s (422,423). The general chemical reactions of these first-generation products are shown in Figure 8.
