✦ Synopsis
The motivation for investigating the partial oxidation of propylene in sub‐ and supercritical water arises from the unique physico‐chemical properties of this medium. In sub‐ and supercritical water propylene oxide will react to 1,2‐propandiol, so this one‐step process would be an alternative for the technically established two‐step process via chlorohydrin or indirect epoxidation.

One promising application of supercritical water as reaction medium is the selective oxidation from methane to methanol. Methanol is one of the most important intermediates in the chemical industry with a world‐wide production capacity of about 29 million tons per year (1996). A direct conversion of
## Abstract Experiments of microcrystalline cellulose conversion in subcritical and supercritical water were conducted at temperatures between 290 and 400°C, a pressure of 25 MPa, and residence times of 0.02–13.1 s using a continuous‐flow‐type microreactor. First, the reaction mechanism of microcry
