High Purity Propargyl Alcohol (CAS 107-19-7) for Industrial Uses

Key Process Steps (Flowchart)

1. Acetylene Preparation: Pure acetylene gas serves as the key substrate.
2. Reaction with Formaldehyde (Reppe Synthesis): Acetylene is catalytically hydrolyzed with formaldehyde in the presence of copper catalysts under controlled temperature & pressure, yielding propargyl alcohol.
3. Purification: Fractional distillation and drying, with analysis to ensure >99% purity (per ISO 17025 calibration).
4. Quality Testing: Each batch verified for density, refractive index, GC-MS impurity profiling, and compliance with ASTM D6886 standards.
5. Packaging: Filled in ISO-certified drums (HDPE or stainless steel) for corrosion resistance.

The entire process is engineered for strict traceability and batch-specific QC, delivering consistent performance across industrial applications.

• High Functional Group Content: The triple-bonded alkyne (–C≡C–) and primary alcohol group enables strong nucleophilicity and reactivity in addition reactions.
• Corrosion Resistance: Its chelating property with transition metals is leveraged in high-performance corrosion inhibitors for oilfield and industrial systems.
• Versatility as Intermediate: Serves as a precursor for synthesis of pharmaceuticals, flavors, pesticides, UV-curable resins/polyurethanes, and rubber additives.
• Stability & Storage: Special packaging with anti-leak lining extends product shelf-life above 12 months (per ISO 22241).
• Low Color & Impurity: Advanced fractionation and GC purification ensure a clear product, minimizing downstream side-reactions.
• Customizable Specifications: Optionally customized for ultra-low water content, color (

1. Oilfield Corrosion Inhibitors

• Data: Global top 10 oilfield chemicals companies use propargyl alcohol for H₂S, CO₂, and saline corrosion control.
• Advantage: Exhibits excellent passivation and resistance in high-T, high-P wells.

2. Pharmaceutical Intermediate

• Scenario: Primary building block for active pharmaceutical compounds (e.g., anti-infectives, APIs, flavors).
• Data: Used in 14+ patented reactions published in 2022 (ref: ACS Omega).
• Advantage: High selectivity in propargylation and alkylation reactions; conforms to FDA/ICH guidelines.

3. Polymers & Resins Industry

• Scenario: Enhances flexibility and crosslink density in specialty resins (UV-cured coatings, adhesives).
• Data: Improves polymer glass transition by 8–13°C, tested according to ASTM D3418.
• Advantage: Promotes abrasion and chemical resistance in finished polymers.

4. Fine & Specialty Chemicals

• Scenario: Raw material for flavors, fragrances, and intermediates in agrochemicals.
• Advantage: Faster reaction kinetics due to triple bond activation sites.

Q1: What is the difference between "propargyl alcohol" and "alcool propargylic"?

A: Both terms refer to the same compound (2-propyn-1-ol, CAS 107-19-7). "Alcool propargylic" is the French denomination, but they are chemically identical.

Q2: What purity levels are available for industrial vs. pharmaceutical grades?

A: Typical industrial grades are ≥99.0%, while pharmaceutical/intermediate grades exceed 99.5% and require ultra-low water/impurity levels certified per ISO 9001.

Q3: What are the standard packaging and storage recommendations?

A: Packed in HDPE/steel ISO drums or IBCs, store at 5–30°C, away from strong oxidizers. Anti-leak and anti-static linings are recommended for safety compliance.

Q4: Which detection methods are applied for product analysis?

A: Gas chromatography (GC) for purity, Karl Fischer titration for water content, and colorimetry (Pt-Co scale) for color assessment. Additional NMR or GC-MS for advanced impurity profiling.

Q5: What installation or transfer regulations apply?

A: Follow international ISO/ANSI chemical handling protocols. Pump transfer lines should use corrosion-resistant, peroxide-free tubing; grounding is required to avoid static hazards.

Q6: What warranty and customer support services are provided?

A: 1-year quality guarantee, full replacement/refund policy for off-spec batches, 24/7 technical consulting, with COAs and logistics tracking under ISO 9001:2015 management.

Q7: Are custom concentrations or blends available?

A: Yes, propargyl alcohol can be supplied in tailored concentrations or diluted with solvent per customer specs for lab-scale or industrial use.

• Typical Delivery: 7–14 business days (ex-works), expedited air or sea available
• Global Logistics: Dangerous goods shipping with full tracking (UN 2924, Class 3.1 regulations)
• Warranty: 1-year replacement/refund for product non-conformance, full traceability
• Customer Service: 24/7 multilingual technical support, rapid sampling, documentation, and COA provision

All shipments comply with international export & handling standards (UN DG Regulations, IMO IMDG Code).
