Organic Chemical Raw Material Propargyl Alcohol CAS 107-19-7

Used as a rust remover, chemical intermediate, corrosion inhibitor, solvent, stabilizer, etc. Organic synthesis intermediates, solvents, and stabilizers for chlorinated hydrocarbons. It can be used alone as a corrosion inhibitor, preferably compounded with substances that have synergistic effects to achieve higher corrosion inhibition efficiency. To increase the corrosion inhibition effect of alkynol in dilute sulfuric acid solution, it is recommended to add sodium chloride, potassium chloride, calcium chloride, potassium bromide, potassium iodide, or zinc chloride, etc

Specifications


Used as rust remover, chemical intermediate, corrosion inhibitor, solvent, stabilizer, etc. Organic synthesis intermediates, solvents, stabilizers for chlorinated hydrocarbons. It can be used alone as a corrosion inhibitor, and it is best to be compounded with a substance that produces a synergistic effect to obtain higher corrosion inhibition efficiency. For example, in order to increase the corrosion inhibition effect of alkynol in dilute sulfuric acid solution, it is recommended to add sodium chloride, potassium chloride, calcium chloride, potassium bromide, potassium iodide or zinc chlorid, etc.

Usage


(1) An important intermediate in organic synthesis. In the pharmaceutical industry, propargyl alcohol is an important intermediate for the synthesis of fosfomycin sodium, fosfomycin calcium, and sulfadiazine, and is also used in the production of pharmaceutical products such as acrolein, acrolein, and vitamin A. In the pesticide industry, it is used to synthesize chlorpyrifos pesticide.


(2) A brightener in the electroplating industry. Propynyl alcohol derivatives are used as an excellent fast brightening agent for nickel plating due to their excellent leveling and brightness properties. Propynol derivatives are basically the condensates of propaynol with epoxide such as ethylene oxide or propylene oxide, such as PAP, PME, and propaynol derivatives, which have a large inhibiting effect. They not only have high brightness, but also have good leveling ability and fast light output. They are excellent nickel plating brighteners. They are combined with pyridine derivatives and alkyne amine compounds to form a typical fourth generation nickel plating brightener, It is widely used in the electroplating industry.


(3) Important rust remover. Propynyl alcohol and its downstream compounds can inhibit the corrosion of metals such as iron, copper, and nickel by acidic substances such as acetic acid, phosphoric acid, sulfuric acid, and hydrochloric acid, and are widely used in the steel industry.


(4) Used for oil extraction. As a key effective component of efficient acidizing corrosion inhibitor under high temperature, high pressure, and high concentration hydrochloric acid in oil and gas wells, it is widely used in the petroleum extraction industry.


(5) It can be used as a solvent, stabilizer for chlorinated hydrocarbons, herbicide, fungicide, etc.
