5. Typical Propargyl Alcohol Uses & Application Cases

Corrosion Inhibitor: In oil/gas fields, refinery pipelines (as an acetylenic alcohol-based corrosion inhibitor for H₂S/CO₂—field-tested by Shell, see ACS), the addition of 0.2–1.5% propargyl alcohol can reduce corrosion rate by 91%.
API Intermediate: Core building block of drugs like Edaravone, herbal actives, and custom alkynes. Used in GMP-certified pharma plants.
Electronics Industry: Solder mask and PCB formulations, utilizing high GC purity / low-metal specs (≤0.5 ppm Fe).
Agrochemicals: Precursor for triazole and pesticide manufacturers, where its high reaction selectivity ensures safe downstream synthesis.
Others: As a crosslinking modifier for resins; also in textile and perfumery compounds engineering.

Real Application Case: In a 2023 field trial, a Southeast Asian refinery replaced 70% of their conventional inhibitor with high-purity propargyl alcohol from TENGER, achieving a 28% reduction in steel corrosion rates and saving $270k in annual maintenance costs. (Cited: NACE Forum)
