Propargyl Alcohol
SINOBIO
2905199090
99.94% Propargyl Alcohol is a high-purity corrosion inhibitor with excellent performance in acidic and neutral environments (pH 2–7). This colorless liquid contains a terminal alkyne group that strongly adsorbs to metal surfaces through chemisorption, forming a protective film (0.1–0.5 μm thickness) that prevents pitting corrosion and scale deposition. Its effectiveness spans oilfields, refineries, and power plants, where it protects carbon steel, copper, and aluminum alloys from acid-induced degradation. With a low dosage requirement (5–50 ppm), it offers cost-effective metal preservation compared to conventional inhibitors like thiourea derivatives. Its high purity (>99.94%) ensures minimal impurities that could cause side reactions or toxicity issues in sensitive applications.

Corrosion Control:
Acid Pickling: Inhibits acid-induced corrosion in steel pickling baths (10–20% HCl/H₂SO₄) at 10–50 ppm, reducing metal loss by 90% (weight loss <0.1 g/m²/hour).
High-Temperature Stability: Effective up to 200°C in geothermal systems and steam boilers, with <5% degradation after 1,000 hours at 150°C.
Multimetal Protection: Suitable for carbon steel (C1010), copper (C1100), and aluminum (AA6061), achieving corrosion rates <0.01 mm/year in neutral water.
Pitting Prevention: Reduces pitting factor from 5.0 to <1.2 in salt spray tests (ASTM B117) for carbon steel.
Process Optimization:
Scale Inhibition: Reduces calcium carbonate deposits in heat exchangers by 70% through threshold inhibition, improving energy efficiency by 10–15%.
Foam Suppression: Controls excessive foaming in acidizing fluids by reducing surface tension, enhancing pumpability and reducing pressure drops by 20%.
Compatibility: Works synergistically with quaternary ammonium compounds and phosphonates, increasing overall inhibition efficiency by 30%.
Environmental Safety:
Low Toxicity: LD50 >2,000 mg/kg (oral rat), meeting OSHA PEL standards (TLV-TWA 1 ppm) for workplace exposure.
Biodegradable: Degrades under aerobic conditions with 85% removal in 28 days (OECD 301D), classified as readily biodegradable.
Low Bioaccumulation: BCF <10 in fish studies, minimizing ecological impact in accidental releases.
Acidizing Treatments:
Protects well casings during hydrochloric acid stimulation (15–28% HCl) at 20–50 ppm, extending service life by 3–5 years.
Used in matrix acidizing of carbonate reservoirs to enhance permeability while preventing wormhole corrosion.
Water Injection Systems:
Prevents MIC (microbial-induced corrosion) in offshore platforms at 5–15 ppm, reducing iron content in produced water by 90%.
Stabilizes injection water with TDS up to 100,000 ppm, maintaining corrosion rates <0.05 mm/year.
Petrochemical Plants:
Inhibits corrosion in distillation columns and reactors handling hydrocarbons, reducing maintenance shutdowns by 25%.
Protects acid storage tanks (HNO₃, H₂SO₄) at 10–30 ppm, preventing leaks and extending tank life by 2x.
Fertilizer Production:
Protects stainless steel tanks from ammonia and sulfuric acid corrosion at 15–25 ppm, reducing iron contamination in products to <1 ppm.
Cooling Systems:
Controls corrosion in once-through cooling water systems at 5–10 ppm, maintaining heat transfer efficiency in condenser tubes.
Reduces fouling in cooling towers by 60%, lowering blowdown requirements and water consumption by 15%.
Desalination Plants:
Reduces chloride-induced stress corrosion in heat recovery units at 10–20 ppm, preventing premature failure of stainless steel components.
Metalworking Fluids:
Protects machined parts from rust during storage and transportation at 0.1–0.5% concentration, providing 6-month indoor protection.
Improves sump life of cutting fluids by 50% through corrosion inhibition and microbial control synergy.
