A chip-type micro reactor array comprises parallel mixer units composed of inverse mixing tees, each followed by a micro channel that it is surrounded by heat exchange micro channels (so called channel-by-channel approach similar to the tube-in-tube concept). Such an integrated device was developed as a stack of microstructured plates made of a special glass, termed Foturan (Figure 4.26). The integrated device was attached to PTFE tubes of various lengths. 

A special-purpose photo-structured glass called FOTURAN (available from Mik-roglas Chemtech GmbH - www.mikroglas.com), which is based on lithium aluminum silicate and is especially useful for creating microchannels and related structures with high aspect ratios. 

Utilizing a commercially available micro reactor, fabricated from Foturan glass, Ryu and co-workers [86] evaluated a series of [2 + 2] cycloadditions as a means of reducing the reaction times conventionally associated with the synthetic transformation. Using a high-pressure mercury lamp (300 W), the reaction of cyclohex-2-enone (155) with vinyl acetate (14-7) (Scheme 6.40), to afford the cydoadduct 156, was used to compare photochemical efficiency within the micro reactor [1000 pm (width) x 500 pm (depth)] and a conventional batch reactor (10 ml).

Also chlorination using sulfuryl chloride as a chlorination reagent is examined [131]. The Mikroglas Dwel Device (Foturan glass, 1000 [tm width, 500 (tm depth, and 1.9 m length, and total hold-up volume of 0.95 ml) was used as a micro reactor. 

Another possibility is the manufacturing of full glass mixers. Multi-plate stacks of structured Foturan glass e.g. for an interdigital micromixer or a cyclone laminating micromixer were fabricated.
