A satisfactory model for predicting monomer conversion in free radical polymerization has been a challenge due to the complexity and rigors associated with classical kinetic models. This renders usage of such an exciting endeavour academia but not exactly so industrial practice. In this study, individual interactive effects three processing conditions (reaction temperature, reaction time initiator concentration) on solution styrene using acetone as solvent was investigated batch reactor...

The quality of biodiesel depend strongly on the reaction parameters or process variables. parameters/variables such as methanol to oil molar ratio, temperature and time, catalyst concentration stirring rate have been explored in this study using one variable at a time technique. step by exploration was carried out synthesis castor (ricinoleic acid) acid methyl ester) solvent environment potassium hydroxide catalyst. Optimum condition 12:1 ratio,60 minutes time,1.5%w/w concentration,65 0 C...

The response surface methodology (RSM) was adopted in ths study to evaluate the influence, interplay and interaction of various process variables on biodiesel yield using methanol castor oil as feedstocks presence bovine bones bio-catalyst.Twenty experimental runs were designed central composite design (CCD). RSM statistical model second order developed. Analysis variance (ANOVA) tests performed find relative influence variables. An optimum 95.12% obtained at 60 0C reaction temperature, 120...

Abstract Efforts were made to synthesize polystyrene (PS) using free radical solution polymerization. Four common solvents with dissimilar polarities, acetone, chloroform, benzene and toluene, two different initiators, selected. The homo-polymerization was conducted in an ace round-bottom pressure flask of diameter 62 mm, a thermo well, which housed the thermometer. reaction temperature maintained at 120°C heater controller, coupled magnetically driven stirrer. One hundred experimental runs...

Batch solution polymerization of styrene was investigated using seven solvents, namely acetone, chloroform, benzene, toluene, acetonitrile, ethyl acetate, and dimethyl sulphoxide (DMSO), to elicit solvent effects on the monomer conversion.Two separate initiators, benzoyl peroxide (BPO) its blend with dicyclohexylphthalate (BPO blend), were used unveil solventinitiator interaction.The results indicate that conversion highly influenced by nature solvent.Acetone gave highest while toluene least...

In this study, the kinetics of free radical polymerization styrene initiated by benzoyl peroxide in polar solvent are described. A model was developed  based on set of   elementary reactions mass balance chemical species and method moment analysis. The modeled equations were solved analytically using Garg et al (G-model) approach for estimation polystyrene average properties such as weight number molecular weights polydispersity which found to vary with reaction conditions monomer...

Herein, the synthesis, characterization and efficiency test of alum obtained from waste aluminium cans were investigated for wastewater treatment. Prior to synthesis alum, subjected physical treatments such as communition(size reduction), plastic components removal, colour label cleaning, pulverization etc. The physically treated later chemically step wisely converted alum-a viable double salt. process economy was found be 99.37%. synthesized purchased analyzed both qualitatively...

Cassava starch hydrolysis was investigated in this study using malt extract, alpha amylase and glucoamylase. The effects of process variables, namely: temperature, pH time were studied optimized for cassava (Manihot esculenta) flour to glucose syrup. Three levels variables used the study. three were: temperature (60, 67 74 oC), (1.5, 2.0 2.5 h) (4.5, 5 5.5). A polynomial regression model developed experimental data. results showed that production reducing sugar strongly affected by variation...
