After dissolution of triacetate 2 (50 mg) in methylene chloride (10 mL), Pd(PPh3)4 (0.1 equiv), p-toluenesulfonic acid (3 equiv), benzyl(triethyl)ammonium chloride (BTEAC, 0.1 equiv, phase-transfer catalyst), and 1 M aqueous sodium hydroxide (10 mL) were added. During the reaction, ...
(Na 2 S 2 O 4 ) is prepared by reacting sodium formate, formic acid or a formic ester with sodium hydroxide and sulphur dioxide or with sodium hydroxide and sodium bisulphite in an aqueous alcoholic solution, condensing the formic ester formed in the reaction and boiled off, adding aqueous ...
Fatty acid methyl ester(FAME) can be produced by transesterification of fats using methanol and different alkaline catalysts such assodiumhydroxide, sodium methoxide, orpotassium hydroxide(Vyas, Verma, & Subrahmanyam, 2010). The unique FAME profile of every microorganism can be employed as a microbi...
In comparison to DGEBA/DDM system, DGEP/DDM showed self-extinguishing capability and could be degraded after 40 min in a sodium hydroxide-methanol solution at 50 °C, due to hydrolysis and alcoholysis of phenylphosphonate structures. To conclude, among the various systems, phosphorous ester based ...
The hydrolysis of esters in the presence of alkalies such as potassium hydroxide (lye) or sodium—a reaction called saponification—is utilized in the preparation of soaps from fats and oils and is also used for the quantitative estimation of esters. Wet chemical fire extinguishers, which are us...

sodium hydroxide (221 mL, 221 mmol)-(1N) was slowly added. The suspension was stirred vigorously and slowly dissolved during 8 hours. The reaction was left stirred at room temperature for 18 hours, then the solvent was removed in vacuo. (1044) DCM (600 mL) was added to the solid and ...
Canola methyl ester (CME), rapeseed methyl ester (RME), linseed methyl ester (LME) and sunflower methyl ester (SME) were synthesized in a batch type reactor using both potassium hydroxide (KOH) and sodium methoxide (CH3ONa) as catalysts. The ester preparation involved a two-step transesterif...
