Microreactors provide

Possibility of quick substitution of new modules for the catalyst and the whole microreactor.

High system efficiency due to shortening the contact time between reactants and the catalyst.

Effective heat and mass exchange between reactants and the catalyst.

High selectivity to the target product.

Possibility of constructing portable installations at the customer’s site.

Lowering the risk of processes with explosive and high-toxic products .

 
State-of-the-Art

A flow microreactor system for fine synthesis processes was assembled using the developed microreactors and micromixers.

Advantages of microreactor systems were demonstrated in processes:

 
Synthesis of iminodiacetic acid (IDAC)

Synthesis of iminodiacetic acid (IDAC): oxidative dehydrogenation of diethanol amine at T=165 °C, P=1.5 MPa).

Specific productivity to (IDAC)- 4.5 g/cm3·h (two orders of magnitude as high as the productivity of autoclave synthesis).

 
 
Synthesis of triethanol amine (TEA)

Synthesis of triethanol amine (TEA): ammonolysis of ethylene oxide at T=130-150 °C, P=4.5 MPa).

Against the synthesis in industrial flow reactors: Selectivity to TEA - 85 % against 20-30 %.

Conversion of ethylene oxide - 90 % against 60-70 %.

Specific productivity to TEA -150 g/cm3·h
