Bisphenol A

Bisphenol A (BPA) is a high volume industrial chemical. It is widely used in making polycarbonate plastics as well as epoxy resins. With its aromatic backbone & hydroxyl moieties, BPA serves as a critical building block. It lends strength & durability to numerous everyday products—from water bottles as well as food-storage containers to coatings lining metal packaging. However, its ubiquity also triggers safety concerns, particularly related to hormonal activity in the body. This detailed profile explores BPA’s chemistry, applications, specifications as well as safe handling, while highlighting why Shakti Chemicals is a trusty provider.

What is Bisphenol A

Bisphenol A (IUPAC: 4,4' isopropylidenediphenol; CAS NO. 80 05 7) is a difunctional phenolic compound produced via the acid-catalyzed condensation of acetone with phenol. The result is a crystalline, slightly soluble white solid (≈0.3 g/L at 25 °C) with a melting point near 155–156 °C, density ~1.217 g/cm³, and negligible vapour pressure. The molecule features two hydroxyphenyl groups joined by an isopropylidene bridge. It serves as a adamant & reactive core in polymer synthesis. Factory wise, 65–70% of BPA is used to make polycarbonate (PC) plastics. It is a priced product. It is valued for clarity, toughness & dimensional stability, while 25–30% is committed to epoxy & vinyl ester resins. Additional niche uses include antioxidants (e.g., in brake fluids), thermal-paper developers as well as minor additives in PVC and polyurethanes. Although BPA is not a plasticizer, its phenolic backbone is indispensable in forming long polymer chains. Global production exceeded ~10 million tonnes in 2022. Despite wide utility, BPA is a known endocrine disruptor (xenoestrogen), prompting regulatory scrutiny, especially in food-contact materials and baby products.

Structure of Bisphenol A

BPA features two phenolic rings connected via a methylidene bridge (-C(CH₃)₂-). The rings often adopt a torsion angle near 91.5°. It contributes to crystalline packing. The hydroxyl groups at the para positions are pivotal reactive sites enabling condensation with phosgene (to form PC) or epichlorohydrin (for epoxy resins).

Here is a basic line-structure formula of BPA:

C15H16O2

Or in SMILES notation:

CC(C1=CC=C(C=C1)O)C(C2=CC=C(C=C2)O)

Each C6H4 represents a benzene ring with a hydroxyl (-OH) group at the para position.

These two rings are joined via a central carbon attached to two methyl groups (–CH₃). It forms an isopropylidene bridge.

Molecular Formula: C₁₅H₁₆O₂

IUPAC Name: 4,4′-(propane-2,2-diyl)diphenol

Handling and Storage

Referencing typical SDS recommendations:

Handling: Avoid dust generation; use local exhaust ventilation. Ground/bond all equipment to prevent static discharge. Wear protective gear—gloves, glares, lab coat.

Storage: Store in cool (<50 °C), arid as well as well-ventilated areas. Store it away from strong oxidizers, acids, or bases. Containers should be tightly packed or vacuumed. Nitrogen blanketing is advisable for bulk storage.

Spills: Sweep/collect material without creating dust. Dispose this as per regulations. Vacuuming with explosion-proof products recommended.

Fire Hazard: Combustible dust—minimize ignition sources. Use water spray, CO₂, or dry chemical extinguishers.

Reactivity: Stable under normal conditions; reactive with oxidizing agents. No risky or hazardous polymerization.

FAQs

What is Bisphenol A used for?

It is widely used to manufacture polycarbonate plastics (~65%) as well as epoxy resins (~25–30%).

What is the chemical formula as well as mol. weight?

The chemical formula is C₁₅H₁₆O₂ & Molecular weight is Mw ≈228.29 g/mol.

Is BPA soluble in water?

Poorly—≈0.3 g/L at 25 °C; more soluble in organic solvents.

What health risks does BPA pose?

It’s a endocrine disruptor; EFSA recently cut tolerable daily intake to 0.2 ng/kg/day, citing consumer exposure concerns.

How should BPA be stored safely?

In sealed containers, ≤50 °C. Put away from fire catching sources, strong oxidizers. Also nitrogen blanketing recommended.

How to handle BPA dust safely?

Try to decrease dust by using grounded & ventilated equipment. Always wear PPE protection & clean spills without air-blowing.
