Disclosed is a method for thermochemically converting a carbohydrate material into ethanol wherein the carbohydrate material and a metal salt are reacted at elevated temperature to form an intermediate carbohydrate complex salt and/or a lactate metal salt which then is pyrolyzed in the presence of water into ethanol. Preferred carbohydrate materials for the process are various sugars and the metal salt preferably is a metal oxide, hydroxide, or carbonate. The intermediate complex and/or lactate salt may be separated from its aqueous reaction mixture prior to its pyrolysis to reduce the ultimate separation of ethanol from water. Alternatively, the metal of the metal salt may be one whose carbonate decomposes to metal oxide and carbon dioxide during the pyrolysis step of the process to generate said metal salt in situ.

Pharmaceutical dosage forms comprising an edible web having deposited thereon or at least partially thereon a particulate medicament, the webs being thereafter fabricated and finished to pharmaceutically elegant solid dosage forms having no medicament exposed on an exterior surface. The doseage forms have a consistency of release of medicament which can be controlled to exacting specifications. The disclosed solid dosage forms are prepared by high speed automated equipment and the process by which they are made is characterized by non-destructive quality control analysis and performance evaluation both conducted on-line and integrated into the manufacturing operation. Included in the scope of the disclosed invention are certain apparatus and methods of manufacture.
