  • Heterogeneous kinetic study for esterification of Acetic acid with Ethanol 
    De Silva, ECL; Bamunusingha, BANN; Gunasekera, MY [Article-Abstract]
    The esterification of acetic acid with ethanol has been investigated in the presence of a low cost ion exchange resin mainly used in the water treatment industry namely Trilite SCR-B as a heterogeneous catalyst. Internal ...
  • Hydration characteristics of paddy in the parboiling process 
    Karunarathna, KDN; Buddhika, AN; Kahatapitiya, KRMG; Gunasekera, MY [Article-Abstract]
    Hydration of 'Bombuwala' and 'No 341' paddy varieties in hot water was studied as a function of time and temperature. The temperature range from 45° C to 70° C and time of soaking not exceeding 4 hours were considered. ...
  • Hydrolysis of ethyl acetate using the cation exchange resin trilite SCR-B 
    Thilakarathna, MG; Fernando, KCN; Gunasekera, MY [Article-Abstract]
    The reaction between ethyl acetate and water is an important reaction in chemical engineering applications. In the absence of a catalyst, the reaction rate is very slow and it is not economical for industrial applications. ...
  • Life cycle inventory analysis for parboiled rice production in Sri Lanka 
    Nadeeshani, E; Gunasekera, MY [Article-Abstract]
    Approximately 70% of the paddy production in Sri Lanka goes through the parboiling process. e parboiling treatment process require energy, water and other resources extracted from the environment and after the process ...
  • Modelling of reactive distillation for Acetic acid esterification 
    Kandanapitiya, KKCW; Gunasekera, MY [Article-Abstract]
    Esterification reactions are limited by chemical equilibrium and therefore they are carried out commercially using either a large excess of one of the reactants or by removing one of the products continuously. The removal ...
  • Production of ethyl acetate using catalytic reaction 
    Bamunusingha, BANN; Gunasekera, MY [Article-Abstract]
    The esterification of acetic acid with ethyl alcohol to produce ethyl acetate proceeds very slowly in the absence of a catalyst. In order to make the reaction faster, both homogeneous and heterogeneous acid catalysts can ...
  • Selection of endpoints for acute effects due to exposure to toxic chemicals in Sri Lanka 
    De Silva, KGVK; Gunasekera, MY; De Alwis, AAP [Article-Abstract]
    This article considers the challenge of setting threshold values or end points for toxic gas exposure from Major Accident Hazards (MAH) to third parties or the public in the Sri Lankan context. Two different categories ...
