This excellent standard work is now in its sixth, completely revised edition. It remains the undisputed definitive source for technological and economic information on the most important primary and intermediary products in the chemicals industry.

The fact that this work has been translated into ten languages as well as the six German and four English editions testify to the global interest in this book. This edition has been extended to include current production data on the most important industrial markets as well as carefully selected references to general and secondary literature.
