The fatty acid methyl ester (FAME) compositions and combustion characteristics of the biodiesel produced from three plant oils under different supercritical methanol conditions were investigated by gas chromatography and thermobalance analyzers. When the reaction temperature increased from 255 to 300 degrees C, the conversion efficiency of rapeseed oil into FAMEs in biodiesel increased from 13% to 98%. Such increase resulted in an improved combustion property of rapeseed biodiesel with decreasing combustion activation energy from 143.6 to 84.2 kJ/mol. The ignition temperatures of the biodiesel produced from rapeseed, soybean and palm oils gradually decreased from 257.6 to 240.2 and 238.0 degrees C, which implied that the biodiesel with more C=C double bonds had higher ignition temperature. The ignition temperature of biodiesel was lower than that of raw plant oil, but higher than that of petroleum diesel. (C) 2014 Elsevier B.V. All rights reserved.

Highlights • The addition of flavonoids could effectively reduce acrylamide formation. • Acrylamide reduction was related to the number of phenolic hydroxyls of flavonoids. • Non-linear dose–response relationship was observed during microwave food processing. • Acrylamide reduction was in correlation with antioxidant activity of products. • Both ANN and MLR models could effectively predict acrylamide reduction. Abstract The aim of this study was to investigate the applicability of artificial neural network (ANN) and multiple linear regression (MLR) models for the estimation of acrylamide reduction by flavonoids, using multiple antioxidant capacities of Maillard reaction products as variables via a microwave food processing workstation. The addition of selected flavonoids could effectively reduce acrylamide formation, which may be closely related to the number of phenolic hydroxyl groups of flavonoids (R: 0.735–0.951, P < 0.001). The rate of inhibition of acrylamide formation correlated well with the change of trolox equivalent antioxidant capacity (ΔTEAC) measured by DPPH (R2 = 0.833), ABTS (R2 = 0.860) or FRAP (R2 = 0.824) assay. Both ANN and MLR models could effectively serve as predictive tools for estimating the reduction of acrylamide affected by flavonoids. The current predictive model study provides a low-cost and easy-to-use approach to the estimation of rates at which acrylamide is degraded, while avoiding tedious sample pretreatment procedures and advanced instrumental analysis.
The stability of pyrotechnic composition used in flame detonator was studied at severe temperatures (–70―130 °C) for 5 d. For single N-LTNR(normal lead styphnate), camera was used to observe the shape and colour of N-LTNR in the DSC(differential scanning calorimetry) furnace during continuous heating and cooling processes. Based on the DSC-TGA(thermogravimetric analysis) results, it can be seen that when the temperature exceeded 110 °C, N-LTNR lost its crystal water, making the energetic material become darker in colour, smaller in dimension, lager in volume and lighter in weight(3.416%); when the temperature was below −40 °C, the phenomenon of sample broking, jumping and cracking happened. For the N-LTNR and Pb(N3)2(lead azide) double layers, the loss of N-LTNR’s crystal water at the temperature higher than 110 °C caused the hydrolysis reaction of Pb(N3)2, and the purity of Pb(N3)2 measured after the temperature cycling decreased from 98.6% to 95.26%. For the flame detonator, the height and diameter of the flame detonator were measured and no apparent changes of them were found. The p-t(pressure-time) test shows that the peak pressure was decreased by 3.9%. Therefore, the operating temperature of this flame detonator should be limited to −40–110 °C.
