1,3:2,4-Dibenzylidene Sorbitol (CAS 32647-67-9): Technical Overview and Applications

1. Chemical Specifications and Key Parameters

Parameter Value
CAS Registry 32647-67-9
Molecular Formula C20H22O6
Molecular Weight 358.39 g/mol
Alternative Names Di-O-(benzylidene)sorbitol
Nucleating Agent ZC-2
1,3:2,4-Di(benzylidene)sorbitol

2. Functional Properties and Industrial Applications

This bicyclic acetal derivative demonstrates unique crystallization control capabilities in polymer matrices. Key functional attributes include:

  • Nucleation efficiency enhancement in polypropylene (PP) and polyethylene (PE)
  • Transparency improvement through spherulite size reduction
  • Mechanical property optimization via crystalline phase modification
  • Thermal stability up to 220°C in polymer processing

3. Comparative Analysis with Alternative Nucleating Agents

Property DBS Sodium Benzoate Talc
Clarity Improvement Excellent Moderate Poor
Cycle Time Reduction 15-20% 5-8% 3-5%
FDA Compliance Food-grade approved Limited approval Restricted use

4. Implementation Case Studies

Case 1: Food Packaging Film Enhancement

A leading European polymer producer achieved 40% haze reduction in BOPP films while maintaining tensile strength through 0.3% DBS incorporation.

Case 2: Automotive Component Optimization

Implementation in injection-molded PP dashboards resulted in 18% cycle time reduction and improved surface finish for a Tier 1 automotive supplier.

5. Client Success Stories

Client A: Specialty Compounds Manufacturer

A North American compounder resolved crystallization inconsistencies in high-clarity PP random copolymers through tailored DBS formulations, achieving 99.5% batch-to-batch consistency.

Client B: Medical Device Producer

DBS-enabled polypropylene syringes demonstrated superior clarity and sterilization resistance, passing ISO 10993 biocompatibility testing.
