In order to perform pilot scale testing using microwaves, we have built a pilot facility in the Osaka Plant and prepared infrastructure which enables us to perform various reaction tests using microwaves. We also have world-leading equipment which enables us to correspond to microwave frequency/ output of 915MHz to 5.8GHz, and power of few kw to 100kw, respectively.

Polyester synthesis using microwaves

Merits of microwave heating
Advantage over normal heating
  • Promotions of reaction and reduction of reaction time
  • High purity product and low by-product
  • Energy saving
  • Usage of none or low amount of solvent
  • Rapid heating and internal heating
Effective for the process of:
  • Long reaction time
  • High reaction temperature
  • High purity required
Reaction example of polyester and the effect of microwave heating
  • In synthesis by microwave irradiation, it is possible to selectively remove water.
  • Because dehydration condensation reaction is promoted, reaction time and energy consumption is reduced compared to conventional methods.
