Methods for preparing quaternary ammonium saltsThe present invention is directed to methods for preparing quaternary ammonium salts, particularly pyridinium and quinolinium salts. By preparing these salts in a solvent selected from the group consisting of propylene glycols, propylene glycol ethers and ...
Through empirical testing by trial and error, different detergent-based solutions composed of particular types and concentrations of detergents, buffers, salts, and reducing agents have been developed to provide the best possible results...
There are two main methods for preparing barium sulfate. One involves the reaction between sulfuric acid and barium salts, while the other involves the reaction between sodium sulfate and barium salts. 1. Reaction between sulfuric acid and barium salts: Ba2+ + SO42- → BaSO4↓ 2. Reaction b...

In recent years, to change the performance and characterization of GC films, functional ingredients such as inorganic salts, phenolic compounds, rosmarinic acid and ginger essential oils have been studied by some researchers11,12,13,14. However, docosahexaenoic acid (DHA) combined with polysaccharides...
For his reason, diesel fuel has been used as synthetic oi for preparing water-in-oil emulsion and also as an agent to test the efficiency on non-ionic surfactant. Table 1. Synthetic oil properties. CharacteristicDensity at 15 °CViscosity at 40 °C/104 °F, cStAPIAsphaltene ...
(2022b) investigated using an ultrasound-assisted and hydroalcoholic-freezing combination modification method for preparing a biosorbent made of waste peach wood branches to remove methylene blue. Initially, the peach wood branches were ground into powder (control sample), mixed with ethanol, stirred ...

Aluminum for the removal of phosphate and water softening. The reaction takes place with phosphate or various alkaline compounds (i.e., bicarbonate, hydroxide or carbonate) that form insoluble aluminum slats [17]. Ferric chloride forming insoluble iron salts together with phosphates or alkaline compou...
