Application of artificial neural network for yield prediction of lipase-catalyzed synthesis of dioctyl adipate.
In this study, an artificial neural network (ANN) trained by backpropagation algorithm, Levenberg-Marquadart, was applied to predict the yield of enzymatic synthesis of dioctyl adipate. Immobilized Candida antarctica lipase B was used as a biocatalyst for the reaction. Temperature, time, amount of enzyme, and substrate molar ratio were the four input variables. After evaluating various ANN conf...
متن کاملاثر نرمکنندههای مختلف بر خواص ماده منفجره زیرآبی PBXN-111
PBXN-111 is a common plastic bonded explosive has been widely used in warhead section of several navy weapons. This charge is based on HTPB resin and prepared with cast-cure method. Isodecyl pelargonate (IDP) as plasticizer is used in PBXN-111 formulation. Considering limitations to prepare IDP, in this research the effect of replacement of dioctyl adipate (DOA) and dioctyl sebacate (DOS) inste...
متن کاملEffect of Hyperbranched Polyesters on HTPB Polyurethane Curing Kinetic
Effects of hyperbranched polyesters on kinetics of the reaction between hydroxyl-terminated polybutadiene (HTPB) and isophorone diisocyanate (IPDI) were investigated. HTPB and IPDI were in-situ cured in the presence of two different hyperbranched polyesters, stearic acid ester-terminated hyperbranched polyester (SHPE) and acetate-terminated hyperbranched polyester (AHPE). The curing processes w...
