.6 kWh/kg). This was because the latter enabled a higher amount of oil to be processed per unit time. Scaling up experiments are in progress with a bigger tank that uses a bigger rotating cavitator with a higher feeding rate. With the aim of producing fatliquors, further tests will be performed to understand whether this type of oxidation is suitable for the subsequent sulfonation reaction. 4 Conclusion This work demonstrated that HC systems can be successfully employed to promote the oxidative polymerization and emulsification of oils. The use of a rotor

1 Introduction Polyaniline (PANI) is among the most studied conducting polymers found in variety of applications such as rechargeable batteries, photonics, optoelectronic devices, biochemical sensing devices ( 1 – 4 ), membrane separation as well as modified electrodes for electro-reduction ( 5 , 6 ). Scientific interest in PANI originates from the fact that this conjugated polymer is unique among conducting polymers ( 7 – 9 ). PANI produced by chemical oxidative polymerization of aniline ( 10 – 12 ), is well known to have good environmental stability ( 1 , 3

Abstract

Propylene oxide polymerization in the presence of layered double hydroxides with different concentration of basic sites on their surface has been studied. It is shown that the polymerization can be catalyzed by both basic and acidic sites. On the basis of kinetic experiments the mechanisms of reaction undergoing were proposed.

shift of the absorption bands ( 39 , 40 ). However, it is difficult to accurately examine the interfacial interaction between the outer CB layer and the inner PEDOT in the composites by FTIR analysis alone ( 41 , 42 ). According to the above analysis, EDOT underwent oxidative polymerization in water/ ethanol to form oligomeric free radicals under the action of initiator (APS) and oxidant (FeCl 3 ) ( Figure 6 ). It is believed that during the PEDOT polymerization process, a small amount of carbon black nanoparticles were encapsulated by PEDOT. However, the CB
