Azeotropic distillation of ethanol-water mixture is accomplished by adding a volatile third component to the liquid which changes the volatility of one of the two components more than the other so the components are separated by distillation. The two components to be separated often have similar boiling point components which do or do not... Continue Reading

 The purpose of this study is the preparation of activated carbon using a suitable industrial sludge. The characterization of two types of industrial sludges showed that paper sludge was a better option over rice husk. The activated carbon produced from pyrolysis of paper mill sludge was chemically activated with various activating... Continue Reading

The project research entailed the production of high quality sealant  incorporating a local raw material for sealing holes and gaps in various materials  like metal and plastic. Two samples of acrylic sealants were produced, the first  samples which is the standard formulations involved the use of silica gel as a  major adhesion promoter and... Continue Reading

The effects of temperature, dielectric constant and catalysis in the kinetics of the oxidation –reduction reactions (involving electron transfer) of N-(2-hydroxy-ethyl) ethylenediammine- N’,N’,N’-Triacetatocobalt (II) by Cu 2+  cation were determined.  The dielectric constant was decreased from 63.05 to 43.18 and it was found that the...
