Product Description

Product Name	Lauroyl Chloride Synonyms: Dodecanoyl chloride \| n-Dodecanoyl chloride \| Lauric acid chloride \| Dodecanoic acid chloride \| C12 Acid Chloride
CAS NO.	112-16-3
Formula & Weight	C₁₂H₂₃ClO (MW: 218.76)
Chemical Structure
Technical Specifications	Appearance: Colorless or yellowish oily liquid Purity (GC): ≥ 98.0% Free Chlorine: ≤ 2.0% Boiling Point: 134-137°C (at 11 mmHg) Density: 0.92 g/mL at 25°C Refractive Index: n₂₀/D 1.445
Key Applications	1. Personal Care & Surfactants (High Demand) Amino Acid Surfactants: Reacts with Sarcosine to produce Sodium Lauroyl Sarcosinate, and with Glutamate for Sodium Lauroyl Glutamate. These are premium, mild surfactants for sulfate-free shampoos and cleansers. 2. Organic Peroxides (Polymer Industry) Initiator Synthesis: The primary raw material for manufacturing Dilauroyl Peroxide (LPO), a critical initiator for PVC production and acrylate polymerization. 3. Pharma & Surface Modification Used to attach hydrophobic C12 chains to peptides or proteins. Surface modification of nanocellulose for hydrophobic materials.
Downstream Synthesis Routes	Route 1: Sodium Lauroyl Sarcosinate Production Lauroyl Chloride + Sarcosine + NaOH → Sodium Lauroyl Sarcosinate + NaCl + H₂O End products: Sulfate-free shampoos, mild facial cleansers, premium toothpaste Route 2: Dilauroyl Peroxide (LPO) Synthesis 2 Lauroyl Chloride + H₂O₂ + 2NaOH → Dilauroyl Peroxide + 2NaCl + 2H₂O End products: PVC polymerization initiator, acrylate curing agent, rubber crosslinking agent
Packaging & Handling	Packing: Plastic Drum, IBC Tank available for bulk orders. Handling: Corrosive liquid. Reacts with water. Store in a cool, dry area under inert atmosphere. Shelf Life: 12 months when properly stored.

Frequently Asked Questions

Q: What is Lauroyl Chloride used for?

Lauroyl Chloride is primarily used as an acylating agent for synthesizing amino acid surfactants (such as Sodium Lauroyl Sarcosinate and Sodium Lauroyl Glutamate) and as a precursor for Dilauroyl Peroxide (LPO), a key polymerization initiator in PVC and acrylate production.

Q: What is the difference between Lauroyl Chloride and Cocoyl Chloride?

Lauroyl Chloride contains only C12 fatty acid chains, providing consistent performance and high purity. Cocoyl Chloride is a mixture of C8-C18 chains derived from coconut oil, offering broader carbon distribution but less uniformity in end-product quality.

Q: How should Lauroyl Chloride be stored and handled?

Store in a cool, dry, well-ventilated area away from water and moisture. Use sealed containers under inert gas (nitrogen) atmosphere. Keep away from heat sources, oxidizing agents, and incompatible materials. Personal protective equipment (PPE) is required during handling.

Q: What purity grades does Royalchem offer?

Royalchem provides industrial-grade Lauroyl Chloride with purity ≥98.0% (GC), suitable for surfactant synthesis and organic peroxide production. Higher purity grades are available upon request for pharmaceutical applications.
