  • Product Description
 

The objective of the present work was to study the effects of the prepared urea-starch resin during application in industries at different temperatures and various times. The isothermal weight loss (X%) of urea-starch resin was investigated at temperature 175, 200, 225 and 250 oC at period of times (10,20,30,40 and 50 min.). The result shows that the amount of weight loss (X%) of urea-starch resin increases with increasing temperatures and time. The activation energy of the isothermal weight loss process during these experiments was calculated and it was varied between (25-32) kJ/mol by varying temperatures from ( 175 to 250) oC at values (2-12)% weight loss of urea-starch resin. The reaction rate constant (K) for temperatures range (175 – 250) oC were changed from (2-33x10-3 L.mol-1.S-1). The degree of reaction was found to be 2nd order reaction for the temperature range (175 – 250) oC. The average enthalpy, entropy and Gibbs free energy of reaction at temperature (298 ?K) was (97.163 J/mol), (192.40 J/mol) and (-57239.16 J/mol ) respectively.
