Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Fractional Distillation During the past eighteen years I have been engaged in investigations which necessitated the preparation of chemical materials in the purest possible state, and as the great majority of these substances were liquids, the process of fractional distillation had, in most cases, to be resorted to for their purification. The difficulties I met with in some of the separations led me to make a careful investigation of the whole subject, and I was thus enabled to devise some new methods and forms of apparatus which have been described from time to time in various scientific journals. It is in the hope that the solution of the difficulties which so often occur in carrying out a fractional distillation may be rendered easier, and that the value and economy of highly efficient still-heads in laboratory work may come to be more widely recognised than is generally the case at present, that this book has been written.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Distillation Principles and Processes The volume on "Fractional Distillation" was written in the hope that it would be of assistance to chemists in overcoming the difficulties so frequently met with in the laboratory, not only in the actual carrying out of the fractional distillation of a complex mixture but also in the interpretation of the results obtained. The last copy was sold shortly after the declaration of war, and the question then arose whether a revised second edition of the book in its original form should be published. It was thought, however, by the Publishers that it would be wiser to extend the scope of the work so as to include distillation on the large scale as carried out in the manufacture of important products. That this change in the character of the book was really advisable became more and more evident as the war increased in intensity and magnitude, because of the immense importance of such materials as acetone, toluene, petrol, glycerine, and so on, the production of which involved processes of distillation on an enormous scale, and for some of which new sources or methods of formation had to be sought and investigated. It was obvious that the larger book could only be of real value if the sections on manufacturing processes were written by chemists thoroughly conversant with the various subjects dealt with, and it was eventually decided that I should edit the book if I could secure the co-operation of experts in the different branches of manufacture. In these preliminary negotiations I received most valuable assistance from my friends, Professor F. E. Francis, D.Sc, Ph.D., and Professor W. E. Adeney, D.Sc, and my sincere thanks are especially due to Professor Francis for the great interest he has taken in the production of the book. Unfortunately the heavy pressure of work entailed on all chemists by the war caused serious delay in commencing the book, and progress has necessarily been slow.

Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1922 edition. Excerpt: ...the more volatile component than the liquid with which it mixes, thereby increasing the proportion of volatile component on the top plate. Continuing, as the composition of the liquid on the top plate increases in the more volatile component, the effect will be felt on the plate below, and after the distillate from the condenser has been returned to the column for a considerable length of time, the effect will be that all of the plates in the upper portion of the column will contain substantially nothing but the more volatile component. When this condition has been reached, if the valve leading from the condenser to the receiver for distillate is then opened, the first portion of vapor which comes over will be that liquid which has collected on the plates in the upper portion of the column and will, therefore, be practically pure component. When the contents of the column have distilled over in this manner, there will be a sudden break in the composition of the distillate and when this break occurs, the fraction is shifted and a small intermediate fraction is then recovered in a separate distillate receiving tank. If this method of complete reflux of the distillate were not practiced, the amount of intermediate fraction between any two pure fractions would be very greatly increased. In the same way, when the benzene has been nearly all distilled over, it is possible to obtain a sharp cut between the benzene and the toluene fractions by refluxing completley for a certain length of time. There will be, of course, a small intermediate fraction consisting of a mixture of benzene and toluene and this intermediate fraction must be returned and mixed with the next charge which is put into the kettle and redistilled. The net capacity of any...
