Influence assessment of inlet parameters on thermal risk and productivity: Application to the epoxidation of vegetable oils

D-optimal design optimization of unsaturated palm fatty acid distillate and trimethylolpropane esterification for biolubricant production

“…The final equations for yield of USFA-TMP tri-ester 6) and ( 7), respectively. It is known that the numerical simulations have been proved to be useful to find safe and efficient operating conditions through a Pareto chart approach and tested with some laboratory experiments [38]. However, D-optimal model design used in this study use probability of seeing the observed F -value (Prob > F value) if the null hypothesis is true (there are no factor effects).…”

“…This earning that for all response values, the discrepancy is constant. It can, therefore, be established that the models are appropriate for application without any alterations to decrease the scatter [38].…”

Recent advances of ring opening of epoxidation of palm oil derived from oleic acid via in situ hydrolysis under moderate temperature

“…14 Few research have been conducted to date employing the best epoxidation process parameters to produce DHSA in situ from epoxidized oleic acid. There are several studies on the optimization of parameters in the epoxidation of Hura crepitans seed oil, 15 rapeseed oil, 16 and cottonseed oil, 17 but there are fewer studies on the oxirane ring opening epoxidized palm oil. Considering that the optimum epoxidation process parameters would produce crude DHSA by in situ hydrolysis of epoxidized oleic acid, a high hydroxyl content would be produced, which indicates high yield of DHSA.…”

Process hazard evaluation for the epoxidation of soybean oil with calorimetry techniques

“…One of the greenest ways to epoxidize such double bonds is the Prileschajew method 8 . Prileschajew oxidation is a liquid–liquid process, 9 where a percarboxylic acid is produced in situ in the aqueous phase from the perhydrolysis reaction and diffused into the organic phase to epoxide the unsaturated groups of the vegetable oils. Solubility in the organic phase and reactivity of percarboxylic acid is higher compared to hydrogen peroxide.…”
