2-Ethylhexyl 3-Mercaptopropionate (CAS 50448-95-8) Comprehensive User Guide

1. Product Overview and Parameter Comparison

Parameter 2-Ethylhexyl 3-Mercaptopropionate Generic Thioester
CAS Number 50448-95-8 Varies
Molecular Formula C11H22O2S Typically C8-C12
Molecular Weight 218.36 g/mol 180-250 g/mol
Flash Point >110°C 90-105°C

Key Advantages: Higher thermal stability, lower volatility, and enhanced compatibility with polymer matrices compared to standard thioesters.

2. Detailed Applications and Use Cases

Primary Industrial Uses:

  • PVC Stabilization: Acts as secondary stabilizer, synergizing with metal soap stabilizers to prevent thermal degradation during processing (160-200°C).
  • Lubricant Additives: Reduces oxidation in synthetic oils at concentrations of 0.5-1.2% w/w.
  • Adhesive Formulations: Improves UV resistance in acrylic-based adhesives by 40-60%.

3. Industry-Specific Usage Scenarios

Case 1: PVC Pipe Manufacturing

Implementation: 0.8-1.5 phr addition reduces processing temperature by 15°C while maintaining tensile strength ≥45 MPa.

Case 2: High-Temperature Grease Production

Results: Extended oxidation induction time (OIT) from 120 min to 380 min at 150°C.

4. Real Customer Success Stories
