PQ Silicate of Soda as a paper size is reacted in the beater with alum to produce a flocculent alumino silicate. This becomes enmeshed and adsorbed on the fibres, and helps to retain the short fibres a n d higher a m o u n t s of rosin size and fillers such as clay. F o r instance, clay retained may be increased 10%. T h e use of 4% of a P Q Silicate* may increase the paper o u t p u t 1%. In addition t o this higher yield, quality is greatly improved— better printing surface, greater strength a n d brighter colors. How can the reaction of PQ Silicate with aluminum salts be useful to you? Let us apply our silicate knowledge to your current problem. *0 Silicate—Ratio 1: 3.22 Trade Marks Reg. U . S . Pat Off

INDUSTRIAL AND ENGINEERING CHEMISTRY
nctics can hardly find m u c h inspira tion in existing books on chemical kinetics. I n particular, there seems to be a complete divorce between theory a n d practice in chemical kinetics. This is not really so but, unfortunately, it is a widepsread im pression. T h e trouble is that it is the wrong part of the theory which frequently retains most of the attention. Like Julius Caesar's Gaul, the theory of chemical kinetics is made of three parts a n d one of them is m u c h better than the other two. T h e first part is the q u a n t u m mechanical problem of interaction between molecular species. This underdeveloped as pect is, fortunately, omitted entirely, as it should be, in "Chemical En gineering Kinetics." T h e second part is t h e statistical mechanical problem. T h e reviewer's feeling here is that all the engineer needs to know about this aspect of theory can be clearly a n d adequately summerized in two paragraphs. Strangely enough, the author spends m u c h time on this part of the theory but not enough to make it intelligible. Moreover, most of what he says about it cannot be used by t h e engineer because it is valid only for elementary reactions and, alas, most reactions, except for a few museum pieces, are not elementary. T h e dis section of a n over-all reaction into its elementary components is t h e third part of the theory a n d is t h e most satisfactory one. M a n y gen eral rules of kinetic behavior can be presented in a form which covers broad classes of reactions irrespec tive of their detailed mechanism. T h e lack of this kind of information in a book o n chemical engineering kinetics is regrettable. Indeed, many useful generalities of interest to r e actor design a r e n o t mentioned— for instance the existence of an opti m u m temperature profile for an ideal tubular reactor along which an exo thermic reversible reaction is taking place. T h e author of this book must be congratulated a n d thanked for giving us without further delay his inter pretation of an important subject. In spite of the serious shortcomings which prevent the book from being properly balanced, this reviewer recommends it to all those interested in chemical reactor design.
