The present invention concerns the field of microreaction devices and of micro-process engineering. It particularly involves devices having micro-channels (internal chambers of micrometric to submicrometric dimensions) for conveying chemical or biochemical mixtures and/or reactions. More specifically, such devices are optimized to achieve high temperature and pressure stresses (i.e. 500° C. and 500 bar). For observation and analysis purposes, the microreaction devices have a wide range of transparency in terms of wavelengths. The subject matter of the present invention relates to a microfluid or microreactor device made of transparent sapphire, preferably in the wavelength range of 150 to 6500 nm, its manufacturing method and to its use.

The present disclosure provides a microchannel device including a base having a defining surface that defines a flow channel and containing silicone, in which the defining surface of the base includes a region in which a surfactant is adsorbed, and a ratio of an amount of secondary ions of the surfactant adsorbed on the defining surface of the base to a total amount of ions detected by time of flight secondary ion mass spectrometry is 0.01 or more, and provides a use application thereof.

A microreactor for photoreactions includes a housing upper part, a lid plate made of a material that allows transmission of light, a flow path plate made of a material that suppresses light reflection and has a high thermal conductivity, and a housing lower part. Light is applied through a window of the housing upper part and the lid plate to a flow path of the flow path plate. The lid plate made of the material that allows transmission of light and the flow path plate made of the material that suppresses light reflection and has a high thermal conductivity are welded each other to form an integrated body.

The disclosure concerns methods comprising forming a phenol and acetone mixture from decomposition of a cumene hydroperoxide or a phenol, acetone, and AMS from the decomposition of a mixture containing dicumyl peroxide in a system comprising one or more reactors where at least a portion of an inner surface of the one or more reactors has a polymer coating and wherein the coating inhibits build-up of a fouling precipitate on the coated inner surface of the one or more reactors as compared to such build-up in the absence of the coating.
