1 equivalent) were mixed in 20 mL dry ethanol and catalytic amount of sodium ethoxide
was added carefully and progress of reaction was monitored through TLC.
In EHOs formulations (both with and without pH controlled), the interaction of DBSCC samples with the solvent occurs through the formation of ethoxide
ion and hydroxide ion.
The presence of Zn, O, and C in the EDX spectra confirms the successful pyrolysis of zinc ethoxide
to form ZnO nanostructures, as illustrated here by (1).
Synthesis of ethyl ester of isano oil was carried out by transesterification with sodium ethoxide
according to the method of Christie .
Catalysts employed were analytical grade potassium hydroxide (85% purity, Vetec), sodium hydroxide (97% purity, F Maia), sodium methoxide (NaMet - 97% purity, Fluka) and sodium ethoxide
(NaEt - 95% purity, Fluka).
The resultant dried precipitate (II) was then refluxed with amyl nitrite in ethanol in presence of sodium ethoxide
for 48 h in dry condition.
The reaction between equimolar amounts of 6-amino-2-(methylthio)pyrimidin-4(3H)-one 1 (prepared by the condensation of thiourea with ethylcyanoacetate in sodium ethoxide
and followed by alkylation with alkyliodide ), 1, 3-indanedione 2, and 4-chlorobenzaldehyde were examined in various solvents and different temperatures (25, 50, 65, and 80[degrees]C) under sonochemical conditions.
A mixture of 1 (0.01 mole), indole (0.01 mole) and sodium ethoxide
[0.5 g Na + 50ml ethanol] was refluxed on water bath for 30 hours.
The treatment is comprised of titanium ethoxide
; 3-glycidoxypropyl-trimethoxysilane; an organic acid; and one or more additives that impart erosion resistance, heat resistance, or a combination thereof to the surface treatment, and where-in the one or more additives are present in the surface treatment in an amount from approximately 20 to 40 volume percent, based on the total volume of the titanium ethoxide
and 3-glycidoxypropyltrimethoxysilane in the surface treatment, and wherein the amount of 3-glycidoxypropyltrimethoxysi-lane is from 25 to 35 volume percent and the amount of titanium ethoxide
is from 15 to 35 volume percent, based on the total volume of the surface treatment.
First, the 30-min ultrasonic vibration before electroless deposition process helps the silicon ethoxide
(Si-O[C.sub.2][H.sub.5]) functional groups react with water to form silanols (Si-OH), which act as the reactive groups at the end of the molecule.
Since both acids and bases catalyze condensation, neutralization of the basic residue, lithium ethoxide
, after termination can greatly slow the rate of viscosity increase in an alkoxysilane terminated polymer.
The resultant dried precipitate (10.0 mmol) was then refluxed with diethyl-malonate (10.0 mmol) in ethanol (50.0 mL) in presence of sodium ethoxide
(20.0 mmol) for 4 hrs.
