Be susceptible in reactor reaction liquid layering, material crystallize the problems such as, cause implementation result undesirable.Although
It is proposed in CN101835734A by adding filler in the duct, to change the scheme of mixed effect in reactor, but still
So apparent technique effect is not obtained.This is also that the reactor equipped with stirring is selected in actual production why as far as possible
The reason of carrying out such condensation reaction.
In recent ten years, the research that synthetic reaction is carried out in micro passage reaction, becomes synthesis chemical field research
Hot spot.Compared to traditional chemosynthesis reaction carried out in conventional reactor, micro passage reaction have large specific surface area,
Mass-and heat-transfer is efficient, good mixing effect, the reaction time is short, easily-controlled reaction conditions, easily extension produces and without amplification safely
The advantages such as benefit.
