The ethanol-NaOH reaction of Taiheiyo coal (C, 77.5; H, 6.3 wt%) was examined under a pressure of 0.1–8 MPa nitrogen or hydrogen, at 300 °C for 1 h. Almost all of the products are extracted with pyridine for the entire pressure range and the extraction yield with ethanol increases ...
X-ray diffraction(XRD) analysis was conducted to examine the crystalline structure of the AuNPs, and indicating the nanoparticles present a face-centered-cubic(fcc) crystalline structure. Moreover, the possible mechanism of the progress and the effect of NaOH on the reduction reaction were discussed...
In the presence of sodium hydroxide, formaldehyde and benzaldehyde react to produce benzyl alcohol by disproportionation reaction. C6H5CHO+HCHO[NaOH]→C6h5CH2OH+HCOONa DescriptionBenzyl alcohol is a component catalyst for epoxy resins. It is also contained in the color developer C-22. ...
Other applications include as a fuel and wood treatment. In industry, it is manufactured through either direct reduction of furfural, or through the disproportionation via the Cannizaro reaction in NaOH solution. The basic raw materials for its manufacturing are waste vegetable materials such as rice...
Methanol, ethanol, straight-chain propanol, isopropanol, straight-chain butanol, sec-butanol, tert-butanol, straight-chain pentanol, and iso-pentanol were used for the reaction of coal with NaOH-alcohol at 290 °C for 1 h. All the products dissolved in pyridine with an extraction yield > 80...
b, Aqueous HMF oxidation over the mono- and bi-metallic Au–Pd catalysts. Reaction conditions: HMF (0.1 M); NaOH (0.4 M); H2O (16 ml); 25 °C; pO2 = 3 bar; 30 min; catalyst amounts for Au@Pd/C and Au–Pd/C:143.1 mg, Au/C: 72.1 mg, Pd/C: ...

Next, 1.5 g Na2SO3 and 1.0 g NaOH (15% and 10% based on lignin) were added to the reaction mixture and heated at 80 °C under reflux for 1 h. After completion of the reaction, the mixture was cooled to room temperature, and it was precipitated by adding 1 M HCl solution to ...
(C.Hs)oSO. + NaOH .- (CoH.)NaSO. + CoH.OH (e) (j) The experimental results show clearly that the ether formed during the reaction contains more than the normal proportion of heavy oxygen. The exact proportion depends on the length of the reaction period. After a period of 3'5 hr...
ROSO3− H+ + NaOH ⇒ ROSO3−Na+ (sodium lauryl sulfate) Another process employs sulfur trioxide in place of CSA. Since no salt is formed in this process, the manufacturers will post add it to the completed product. Other by-products include unsulfated alcohol and sodium sulfate. These...
