0 mL of sodium methoxide
solution in methanol/diethyl ether (1:1) was added.
Garcia-Ochoa, Kinetics of the Production of Glycerol Carbonate by Transesterification of Glycerol with Dimethyl and Ethylene Carbonate Using Potassium Methoxide
, a Highly Active Catalyst, Fuel Process.
The beaker is closed and then stirred for about half an hour and Sodium Methoxide
is formed as a result.
Transesterification of cantaloupe seed oil: Initially, the methyl esters of extracted cantaloupe seed oil (CSO) were prepared by transesterification following a standard method of 6: 1 methanol to oil molar ratio and 1% wt/wt of sodium methoxide
as the methylating agent.
0%) and sodium methoxide
(Sigma-Aldrich: 95%), both added to the mixture of raw material at a concentration of 15 mmol [100g.
(MeONa) was prepared by adding freshly cut small pieces of Na (2.
Biodiesel (fatty acid methyl esters) is another potential source because sodium (Na) or potassium (K) methoxide
catalyzes the reaction of vegetable oils with methanol to form methyl esters.
30% solution in methanol 500ml,150.
An example of alkali catalyst includes NaoH, KoH, carbonates, sodium methoxide
and sodium peroxide.
The first is commonly called the methoxide
DPC, BPA, sodium methoxide
, lithium hydroxide (all from Sigma-Aldrich chemicals) were all high purity products and were not purified before use.
The procedure was started by depositing in a vial (washed with hexane and dried for 2 h at 300[degrees]C) 2ml of hexane and 40 mg of abdominal fat at 40[degrees]C for 1 min, and after this time, 100 [micro]l of sodium methoxide
were added (prepared with NaOH 2M in absolute methane), was shaken vigorously for 2 min, was heated for 5 min (40[degrees]C) and was centrifuged at 5000 rpm for 10 min.
