Synthesis of a novel protein‐based plastic using sub‐critical water technology

Kinetic and Thermodynamics studies for Castor Oil Extraction Using Subcritical Water Technology

“…The activation energy, Ea, and the frequency factor, A, were calculated from these values using equation 5 . Accordingly, the values of Ea and A were 73 kJ mol 1 and 946002 min 1 , respectively for castor seed oil. The value for the activation energy indicates a semi diffusion control process which mean both diffusion and reaction are controlling the process with predominate diffusion control over the process.…”

Simulation of fast reactions in batch reactors under sub‐critical water condition

“…In the very near future we are going to present the experimental data for the kinetic study of the synthesis of a proteinbased biodegradable plastic prepared from the bovine serum albumin in a batch reactor, which has been synthesized in our previous work 23 (as described in the introduction section). Such results could be used to show the validity of the present strategy and kinetic model.…”

“…It is important to note that the present work affords the first step in clarifying the kinetics of the synthesis reaction of our novel protein-based plastic synthesized previously, 23 while providing theoretical bases for studying other similar fast reactions using tube batch reactors under sub-critical water conditions or even classical atmospheric conditions.…”

“…One such case was in our previous work. 23 In that work we succeeded in synthesizing a novel proteinbased plastic from the bovine serum albumin (a water-soluble protein present in the blood) using sub-critical water technology without the need of any additional catalyst or initiating agents in batch reactors. The optimum synthesis conditions under the sub-critical water condition were found to be in the range of 523-548 K within a reaction time of 0.5-1 minute.…”

“…Moreover, they considered only the effect of the heating up period on the reaction kinetics while neglecting other periods (such as the cooling down period) that could affect the conversion during the course of the reaction, especially at a very fast reaction as the one addressed in our previous work. 23 Therefore, the present work provides a comprehensive analysis of the temperature profile of a tube batch reactor under different sub-critical water conditions both theoretically and experimentally. Moreover, a complete analysis for the kinetic behavior of a modeled fast reaction assuming a first order kinetic is presented as well.…”
