Intermediate Production of Mono- and Diolein by an Immobilized Lipase from Candida antarctica
Lipase from Candida antarctica, fixed on macroporous acrylic resin, has been used for the intermediate production of mono- and diolein by hydrolysis of triolein. The effect of altering concentrations of triolein and glycerol and the function of the molecular sieve on the hydrolysis reaction of triolein were investigated. The highest hydrolysis yield was observed for the utmost concentration of ...
متن کاملBiodiesel Production of Capparis Spinosa Oil via Trans-Esterification Reaction by Using NaOH Catalyst and Its Pilot Synthesis Design
Energy obtained from renewable sources has increased its participation in the energy matrix worldwide, and it is expected to maintain this tendency. Both in large and small scales, there have been numerous developments and research with the aim of generating fuels and energy using different raw materials such as alternative crops, algae and waste cooking oil. Capparis spinosa seed (containing 3...
متن کاملBoron trifluoride etherate; highly efficient catalyst for synthesis of tert-butylamides via modified Ritter reaction in solvent free condition
Highly efficient method for the preparation of N-tert-butyl amides by reaction of nitriles with tertbutylacetateis described using boron trifluoride etherate in solvent free condition. Selective amidation ofbenzonitrile in the presence of acetonitrile was also achieved.
متن کاملTransesterification of Waste Cooking Oil for Biodiesel Production Using Modified Clinoptilolite Zeolite as a Heterogeneous Catalyst
Reduction of fossil fuels sources, increasing of pollution gases emission, and global warming effects increase the demand of renewable fuels. One of the main candidates of alternative fuels is biodiesel. Biodiesel limits greenhouse gas effects due to the closed CO2 cycle. Biodiesel has more biodegradability, lower combustion emissions such as CO, SOx, HC, PM and lower toxicity than petro diesel...
متن کاملTriterpenoids from the Herbs of Salicornia bigelovii.
A new nortriterpene saponin, 3-O-β-d-glucuronopyranosyl-30-norolean-12,20(29)-dien-23- oxo-28-oic acid, namely bigelovii D (11), was isolated from the hydroalcoholic extract of herbs of Salicornia bigelovii along with 10 known saponins (1-10). Their chemical structures were identified on the basis of spectroscopic analyses including two-dimensional NMR and a comparison with literature data. Som...
