mixture is concentrated under reduced pressure with heating and stirring. The distillation headis replaced by a water-cooled reflux condenser, and the residue is dissolved in 1 L of 6 Msodium hydroxide and refluxed for 4 hr. The mixture is saturated with potassium carbonate(ca. 400 g); cooled...
Solubility of a substance is a basic property of a solid/ liquid or gas. It depends on both physical(temperature, pressure) & chemical(pH of the solvent) properties of both the solute & the solvent. The extent of solubility of a substance in a solution is seen by saturation concentration,...
Process for the catalytic hydrogenation of a nitrite in the presence of an amine and a catalyst wherein the catalyst is a liquid-rinsed Raney-type catalyst contacted with a hydroxide prior to contacting the catalyst with the amine. The process results in higher selectivity in the formation of ...
Is NH4OH an acid or base? Is C2H5OH an acid or base? What acid and alkali make sodium chloride? Is NH3 a base? Is lithium bicarbonate soluble in water? Is salt acidic or basic? How many atoms are in lithium hydroxide? Is lithium a solid, liquid or gas? Is milk considered an acid...
Wet flue gas desulfurization refers to the process in which the desulfurizer is desulfurized in a wet state (liquid or slurry state). The wet desulfurization technology is mature and the desulfurization efficiency is high. The desulfurization product is generally liquid or sludge, which is difficul...

The vapors must be condensed by cooling to separate the liquid or oil, leaving char as a solid byproduct (Tian et al., 2013). These factors influence the process parameters, such as operating temperature, reaction time, pressure, and WAS properties, as well as the amount and quality of ...
A solution of 3,4-bis(benzyloxy)phenol 3 (0.5 g, 1.63 mmol) in EtOH (6 mL) was treated with potassium hydroxide (91 mg, 1.63 mmol) and epichlorohydrin (151 mg, 1.63 mmol) and continued stirring at ambient room temperature for 6 h and then concentrated in ...
A well-known basic titration example is the titration of acetic acid (CH3COOH) in vinegar with sodium hydroxide (NaOH): More information of what titration is, can be found at the Basics of Titration guide. Titration explained: This video shows the basics of titration theory and details the ad...
Water is the only pure substance found naturally in all three states of matter: solid; liquid and gas. Water may take many forms; the solid state of water is commonly known as ice or amorphous solid water; the gaseous state is known as water vapour or steam; and the common liquid phase...
