Fortuitous radical reactions in furfural and charcoal reactors

Article Abstract:

Research demonstrates that furfural chemical is involved in the production of aromatics and unsaturated compounds besides being a raw material to a wide range of industrial chemical products. Data indicate that during the production of furfural from cellulose, diacetyl and 2,3-pentanedione are generated in large quantities.

Furfural production needs chemical innovation

Article Abstract:

The need for innovation in the search for higher yields than are found in current industrial processes for furfural is discussed. Innovation seems to be a blasphemous word in some parts of the chemical industry, and unjustifiably so. New things are sometimes desirable. The inventors in industrial furfural processes have not investigated the reasons for yields only half as great as those of analytical chemists. Oat hulls are still reacted with aqueous sulfuric acid and steam at 153 degrees Celsius with old rotating digesters. Bosch Projects Enterprises Ltd. since 1999 has made furfural by a gradual decompression process, with the trade name Suprayield. Topics include process comparison, the decisive factor, and remedies.

Gaseous acid catalysis: an intriguing new process

Article Abstract:

Gaseous acid catalysis is an intriguing new process according to a furfural expert. To create appropriate conditions in a reactor comminuted raw material must be in the reactor with a stream of superheated steam at atmospheric pressure and with a small quantity of hydrochloric acid dispersed in the stream with a vaporizer. The gas might be expected, in combination with the solid raw material, to catalyze the conversion of pentosan to furfural. In fact this does happen, to the great surprise of skeptics. The surface of a solid reagent sets the stage for the formation of a strange ionized species from un-ionized gases. The result is that the ionized species catalyzes the conversion of the reagent on which it was formed. Oxonium is the term preferred by the Intnl. Union of Pure and Applied Chemistry for hydronium ions.
