Description
Propargyl alcohol propoxylate is an organic acid used in chemical mechanical polishing (cmp) compositions as a corrosion inhibitor. It has been shown to inhibit the growth of erythromycin-resistant bacteria by binding to metal ions. It also has surfactant properties and can be used as a surfactant or emulsifier in detergents, cosmetics and other products. The phosphite group provides a carboxylate group which reacts with the metal on the surface of the pipe to inhibit corrosion.
Chemical Properties
Propargyl alcohol propoxylate (PAP) is a clear colorless to yellowish liquid that can be mixed with water and most polar organic solvents.
Uses
PAP is the condensate of propargyl alcohol and propylene oxide, which is used as brightener and leveling agent for nickel plating. It is effective in protecting steel and aluminum from corrosion in acidic and neutral media.
Definition
PAP is an enzyme produced by the prostate. It may be found in increased amounts in men who have prostate cancer. Also called prostatic acid phosphatase.
General Description
PAP (propoxylated propargyl alcohol, propoxylated alcohol, propargyl alcohol propoxylate) is the reaction product of 2-propyn-1-ol with methyloxirane. It is the simplest stable alcohol that contains an alkene functional group. It is a top brightener in nickel electroplating baths at a concentration of 10-30 mg/L. It is also used in rust removers, acid cleaners, car wash equipment, and acid rim cleaners.
