Frequently Asked Questions (FAQs)-Phenol 

What is Phenol?

It is an aromatic alcohol with formula C₆H₅OH and CAS 108-95-2, used as a monomer and disinfectant. It’s a crystalline solid that polymerizes with aldehydes for resins and acts as an antiseptic.

How is Phenol used in resin production?

It is condensed with formaldehyde under acidic or basic catalysis at 80-100°C, forming novolac or resole resins for adhesives and coatings with tunable cure rates.

Is Phenol safe for industrial handling?

Handle with PPE—it’s corrosive and a skin sensitizer; LD50 317 mg/kg oral, but stabilized grades minimize risks in ventilated facilities.

What is the shelf life of Phenol?

In inert-sealed containers at <30°C, molten phenol remains stable for 12-18 months, with minimal oxidation—monitor color for purity.

Can Phenol be used in pharmaceutical synthesis?

Yes, it’s USP-compliant for intermediates like salicylates, with low heavy metals (<5 ppm) ensuring clean API production.

Does Phenol affect solution pH?

Its weak acidity (pKa 10.0) lowers pH mildly in water, but buffers easily for neutral formulations in disinfectants.

What packaging options are available for Phenol?

We supply 230kg steel drums for molten, 25kg bags for solid, and 1000kg IBCs, all UN-approved for corrosives (UN 2821).
