“…32 For heating of a single plate or stacked microreactors, tube furnaces can also be utilized to reach high temperatures 26. 41 In some cases infrared lamps have been used to reach temperatures of about 450 °C in the channels, while keeping the rest of the wafer relatively cool by nearby cooling tubes 35. To achieve high heating efficiencies several groups have integrated either a Pt strip30 or a NiCrome wire22 or a thin metallic film along with its connected electrodes39, 42 into the microreactor during its fabrication.…”

Microreactor technology and continuous flow processing in general are key features in making organic synthesis both more economical and environmentally friendly. When preformed under a high-temperature/pressure process intensification regime many transformations originally not considered suitable for flow synthesis owing to long reaction times can be converted into high-speed flow chemistry protocols that can operate at production-scale quantities. This Focus Review summarizes the state of the art in high-temperature/pressure microreactor technology and provides a survey of successful applications of this technique from the recent synthetic organic chemistry literature.

“…For example, Semikolenov et al added small amounts of pyridine to a solution of pinan-2-ol to suppress side reactions and increase linalool selectivity [22]. Contrarily, Buddoo et al preformed the isomerization reaction in a multichannel micro-reactor system to increase conversion and selectivity compared with traditionally used tubular reactor systems [23].…”

Abstract:Linalool is an important intermediate for syntheses of isoprenoid fragrance compounds and vitamins A and E. One process option for its production is the thermal gas-phase isomerization of cis-and trans-pinan-2-ol. Investigations of this reaction were performed in a flow-type apparatus in a temperature range from 350-600 °C and a residence time range of 0.6-0.8 s. Rearrangement of the bicyclic alcohol led to linalool, plinols arising from consecutive reactions of linalool and other side products. Effects of residence time, temperature, surface-to-volume-ratio, carrier gas, and the presence of additives on yield and selectivity were studied. Furthermore, the effects of such parameters on ene-cyclization of linalool affording plinols were investigated. Results indicate that manipulation of the reaction in order to affect selectivity is difficult due to the large free path length to other molecules in the gas phase. However, conditions have been identified allowing one to increase the selectivity and the yield of linalool throughout pyrolysis of pinan-2-ol.
