Biodiesel, as an alternative fuel for petroleum-based fuel, has recently acquired significant attention. The current study focused on using biowaste to produce catalysts low-cost biodiesel manufacturing. Orange peels (OP) were used make carbon-based solid acid with sulfonic group (–SO 3 H) density of 1.96 mmol g ?1 via a “one-pot” carbonization-sulfonation treatment. Under the optimized reactio...

This study examines the effect of UV irradiation on yield and physical characteristics biodiesel from candlenut oil using a TiO 2 -K O/natural zeolite composite. Natural was activated with KOH impregnated . The formed composite analyzed an X-ray diffractometer. Biodiesel synthesized to methanol molar ratio catalyst loading (w/w oil) 1:4, 1:6, 1:8, 2, 4, 6%, respectively. XRD analysis shows peak...

Pesticide foliage treatment is used in agricultural production to protect plants from diseases, pests, or weeds. Tank-mix adjuvants added the barrel can improve effective utilization rate of pesticides. Herein, a comparative study was conducted investigate effect three kinds tank-mix adjuvant on deposition, absorption, and permeation behavior epoxiconazole chlorantraniliprole solutions. Surface...

The effects of particle size, fermentation, roasting time and roasting temperature of cocoa nibs on cocoa butter extraction using supercritical fluid technology were studied. The effect of particle size was studied using cocoa liquor (D = 0.074 mm), ground cocoa nib (D = 0.25–0.50 mm and 1.0–1.2 mm) and whole cocoa nibs at 35 MPa, 60 C and flow rate of 2 ml/min using supercritical carbon dioxid...

Fatty acids are transported to cells from a variety of different moieties in the plasma. In this study, using oleate and human umbilical vein endothelial cells, we asked whether the vehicle that delivers fatty acid to cells has an influence on its metabolism upon its incorporation into the cell. For oleate vehicles, we compared free oleate bound to albumin with oleate in low density lipoprotein...

The hydrolysis of methyl oleate by pancreatic lipase (EC 3.1.1.3) is inhibited by added normal alcohols. The efficiency of inhibition increases with the chain length of the alcohol, attaining a maximum at 10 carbon atoms. A further increase in chain length causes no further increase in inhibitory action. The data have been successfully treated by assuming that the reaction occurs at an interfac...

Five branched oleochemicals were prepared from commercially available methyl oleate and common organic acids; and their lubricant properties were determined. These branched oleochemicals are characterized as 9(10)-hydroxy-10(9)-ester derivatives of methyl oleate. These derivatives show improved low temperature properties, over olefinic oleochemicals, as determined by pour point and cloud point ...
