In Chapters 3-6, the commercially important chemical classes of dyes and pigments are discussed in terms of their essential structural features and the principles of their synthesis. The reader will encounter further examples of these individual chemical classes of colorants throughout Chapters 7 10 which, as a complement to the content of the earlier chapters, deal with the chemistry of their application. Chapters 7, 8 and 10 are concerned essentially with the application of dyes, whereas Chapter 9 is devoted to pigments. The distinction between these two types of colorants has been made previously in Chapter 2. Dyes are used in the coloration of a wide range of substrates, including paper, leather and plastics, but by far their most important outlet is on textiles. Textile materials are used in a wide variety of products, including clothing of all types, curtains, upholstery and carpets. This chapter deals with the chemical principles of the main application classes of dyes that may be applied to textile fibres, except for reactive dyes, which are dealt with exclusively in Chapter 8. 

There are hundreds of papers dealing with the control of a wide variety of chemical reactors. However, there is no textbook that pulls the scattered material together in a cohesive way. One major reason for this is the very wide variety in types of chemistry and products, which results in a vast number of different chemical reactor configurations. It would be impossible to discuss the control of the myriad of reactor types found in the entire spectrum of industry. This book attempts to discuss the design and control of some of the more important generic chemical reactors. 

Whichever technique is used - paper chromatography, thin layer chromatography, a column of material - separation will be achieved, but different rates of flow or i f value will be recorded. Different powders are used to achieve different separations. Research in the area of analytical chemistry means that different variations of the techniques are being developed periodically. The products can be separated using chromatography then the separated components characterized using mass spectrometry or various types of spectroscopy. 

This reading simply explains the importance of chemistry in our lives. You can see chemistry in every part of our life. For example, while preparing this textbook we used pencils, pens and papers. To type it, computers were used and printers to print its pages with different inks (paints) paper and printing machines were also utilized. All materials and machines used in the printing of this book are also the products of chemicals. In other words, they are produced with the help of different elements or/and compounds. All these are the subjects of chemistry. Yet another example, what if you were to become ill, how would your ailment be diagnozed ...
