| Abstract: | Microcapsule containing paraffin as an internal phase is prepared by direct preparation process in 100 L reactor. The microcapsules are characterized, and the impact of pilotscale experiment on the process is discussed. The results show that the property of pilotscale products is similar to the property of laboratory-scale products. The microcncapsulation ratio of product is 70% ,and the average diameter is 54.0 μm in ethanol. The thermal analysis results show that the phase transition temperature ranges from 313 K to 353 K. The endotherm peak temperature, phase transition enthalpy and heat-resistant temperature are 338 K, 114 J/g,523 K, respectively. |
