Usage

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.

Primary Alcohols via Nickel Pentacarboxycyclopentadienyl Diamide Catalyzed Hydrosilylation of Terminal Epoxides

The efficient and regioselective hydrosilylation of epoxides co-catalyzed by a pentacarboxycyclopentadienyl (PCCP) diamide nickel complex and Lewis acid is reported. This method allows for the reductive opening of terminal, monosubstituted epoxides to form unbranched, primary alcohols. A range of substrates including both terminal and nonterminal epoxides are shown to work, and a mechanistic rationale is provided. This work represents the first use of a PCCP derivative as a ligand for transition-metal catalysis.

ACETONITRILE DERIVATIVE, PEST CONTROL AGENT, AND METHOD OF USING THE SAME

An acetonitrile derivative represented by the general formula (I): (I) (wherein A represents (VV) or (WW) B represents (XX) (YY) or (ZZ) and R represents hydrogen, C1-6 alkyl, etc. (Q1, Q2, Ar1, and Ar2 each represents phenyl, substituted phenyl, etc.; R1, R2, R3, R4, R6, R7, and R8 each represents hydrogen, C1-6 alkyl, etc.; R5 represents C1-6 alkyl, etc.; G represents NR10, etc.; W represents O, S, NR9, etc.; R9 and R10 each represents hydrogen, etc.; and n is an integer of 0-4)). The acetonitrile derivative is remarkably active in controlling pests even when used in a small dose. It is useful as an agricultural or horticultural bactericide or an animal parasite control agent.
