Benzoic Acid

Benzoic Acid:

Benzoic acid (C7H6O2, CAS No. 65-85-0) is an aromatic carboxylic acid utilized as an intermediate in industrial chemical synthesis and as a precursor for downstream benzoate derivatives. Commercial production is executed via the catalytic liquid-phase air oxidation of toluene, yielding technical, food, and pharmaceutical grades designed for large-scale chemical processing, polymer modification, and preservative manufacturing.

Applications:

Industrial consumption of benzoic acid is concentrated in core manufacturing sectors:

Plasticizer Production: Esterification with glycols (e.g., diethylene glycol, dipropylene glycol) produces dibenzoate plasticizers utilized in PVC compounding, adhesives, and sealants.

Sodium & Potassium Benzoate Synthesis: Neutralization with sodium hydroxide or potassium hydroxide generates antimicrobial preservatives for food, beverage, and industrial applications.

Alkyd Resins & Coatings: Functions as a chain terminator and modifier in alkyd resin formulations, controlling molecular weight and improving gloss, hardness, and chemical resistance in surface coatings.

Chemical Synthesis Intermediate: Acts as a precursor for benzoyl chloride, benzyl benzoate, and various agricultural chemical formulations.

 

Pharmaceutical Manufacturing Relevance:

For formulations requiring compliance with pharmacopeial standards, our benzoic acid meets USP, BP, and EP monograph requirements.

Excipient and Antifungal Agent: Utilized in topical pharmaceutical preparations as an antiseptic and antimycotic agent.

Impurity Profile: Controlled levels of chlorinated compounds and heavy metals ensure compatibility with active pharmaceutical ingredients (APIs), preventing side reactions during esterification or salt formation.

Regulatory Support: Manufactured under current Good Manufacturing Practices (cGMP) frameworks, complete with full batch traceability, BSE/TSE-free certification, and ICH Q3D elemental impurity assessments.

 

Grade & Quality Requirements:

Technical Grade (99.0%): Optimized for resin synthesis, plasticizer production, and industrial chemical intermediates where trace organic impurities do not interfere with downstream yields.

USP / BP / FCC Grade (99.5% - 100.5%): Purified via fractional crystallization to meet strict limits on residual toluene, chlorinated derivatives, and heavy metals for food, cosmetic, and pharmaceutical processing.

 

Quality Control:

Lot-to-lot consistency is maintained through systematic analytical validation prior to packaging.

In-House Instrumentation: Every production batch is tested via High-Performance Liquid Chromatography (HPLC) for assay verification and Gas Chromatography (GC) for residual toluene quantification.

Retain Samples: 1-kg production retain samples are archived for 2 years in climate-controlled conditions to allow retroactive verification if required.

Third-Party Verification: Pre-shipment inspection reports from SGS, Intertek, or equivalent agencies can be arranged upon request prior to container loading.

 

Technical Documents:

COA (Certificate of Analysis): Representative batch analysis available for download or immediate transmission via email upon inquiry. Includes actual assay, melting point, moisture, and impurity values.

SDS (Safety Data Sheet): Compliant with GHS hazard communication standards (OSHA 29 CFR 1910.1200 and EC No 1907/2006 REACH). Details acute toxicity (Skin Irrit. 2, Eye Dam. 1), proper handling PPE, and firefighting measures.

TDS (Technical Data Sheet): Comprehensive parameter breakdown, recommended storage conditions, and packaging dimensions.

 

Packaging & Storage:

Standard Packaging:
25 kg net weight multi-layer kraft paper bags with inner polyethylene moisture barrier liners.
500 kg / 1000 kg woven polypropylene bulk bags (FIBC) with discharge spouts and PE liners.
Palletization: Bags are stacked on ISPM 15 heat-treated wooden pallets, stretch-wrapped, and secured with strapping bands for container transport.
Storage Conditions: Store in a cool, dry, well-ventilated area away from strong oxidizing agents and strong bases. Keep containers tightly closed to prevent moisture absorption and caking. Shelf life is 24 months from the manufacturing date under recommended storage conditions.
