WebThe most common derivative used to make the OH group into a good leaving group is the Tosyl group (para-toluenesulphonate). It can be formed by reacting an alcohol with p-toluenesulfonylchloride (TosCl) in the presence of a base (such as pyridine) that acts to remove the HCl that is produced). WebBackground: Occluded central venous lines (CVLs) is a major problem in pediatric patients. Methods: To relieve obstructed catheters, infusions of ethanol (up to 3 mL of a 70% solution) for presumed lipid occlusions and hydrochloric acid (HCl, 0.1 N, up to 3 mL) for presumed mineral and drug precipitates were given in an attempt to relieve obstructed …
