SYNTHETIC TANNINS

PRODUCTION AND APPLICATION

AUTHOR'S PREFACE
Whilst the synthesis of the natural tannins has been successfully
outlined by Emil Fischer, it has been left to the Chemical Industry,
notably the Badische Anilin und Soda-fabrik in
Ludwigshafen-on-the-Rhine, to discover the means of making possible the
production of the synthetic tannins.
The scientific results of Fischer's researches are to-day common
knowledge, and these, together with questions arising therefrom, will
only be lightly touched upon in the book herewith presented. Even an
attempt at enumerating the present synthetic tannins has so far not been
published, and I have therefore availed myself of the opportunity of
making a brief summary of them. My work at the B.A.S.F. deepened my
insight in this new field; ample opportunity of applying these synthetic
products in practice was given me when, as a result of the war, I was
appointed technical consultant to the Austrian Hide and Leather
Commission, and in this capacity was called upon to act as general
adviser to the trade.
