Check washing process of washing a check is relatively simple and can be accomplished with basic solvents. The actual solvent is largely irrelevant — more importantly, the polarity of the solvent must match the polarity of the dye in the ink. For example, an ink that is mostly made of a polar dye would require a polar solvent (e.g. acetone or isopropanol). Both nail polish remover (acetone) and rubbing alcohol (isopropanol) are able to pull most common inks away from paper in minutes. Similarly, a non-polar dye would require a non-polar solvent (e.g. toluene or a similar hydrocarbon). Check washing Check washing
Choline chloride it accelerates growth. It forms a deep eutectic solvent with urea, ethylene glycol, glycerol, and many other compounds. It is also used as a clay control additive in fluids used for hydraulic fracturing. Other commercial choline salts are choline hydroxide and choline bitartrate. In foodstuffs the compound is often present as phosphatidylcholine. Choline chloride Choline chloride is an organic compound with the formula (CH3)3NCH2CH2OH]Cl. It is bifunctional, containing both quaternary ammonium salt and an alcohol. The cation is choline, which occurs naturally. It is a white, water soluble salt used mainly in animal feed. In the laboratory, choline can be
