Overview
Phenyl acetate is an organic ester derived from acetic acid and phenol. It is widely used in the fragrance and flavor industry due to its sweet, floral aroma reminiscent of honey or jasmine. The compound also serves as a key intermediate in pharmaceuticals and agrochemicals. Industrial production typically involves the esterification of phenol with acetic anhydride or acetyl chloride. Its stability and solubility in organic solvents make it a versatile ingredient in formulations requiring controlled release or masking of odors.
Physical and Chemical Properties
Phenyl acetate is a colorless to pale yellow liquid with a characteristic aromatic odor. It has a density of 1.075 g/cm³ and boils at 195–196 °C. The compound is highly soluble in ethanol, ether, and benzene but only slightly soluble in water. Chemically, it exhibits typical ester properties, including hydrolysis under acidic or alkaline conditions to yield phenol and acetic acid. Its flammability (flash point: 76 °C) necessitates careful handling to avoid ignition sources. The molecular structure contributes to its stability under normal storage conditions.
Main Applications
In the fragrance industry, phenyl acetate is valued for its honey-like scent, often used in perfumes, soaps, and cosmetic products. It also acts as a flavoring agent in food products, though in limited quantities due to regulatory guidelines. Pharmaceutical applications include its use as an intermediate in synthesizing analgesics and antiseptics. Additionally, it serves as a solvent for resins and cellulose derivatives in industrial coatings. Recent research explores its potential as a green solvent in specialty chemical production.
Safety and Storage
Phenyl acetate is classified as an irritant, capable of causing skin and eye discomfort upon contact. Proper personal protective equipment (PPE), such as gloves and goggles, is essential during handling. Adequate ventilation is required to prevent vapor accumulation. Storage should be in tightly sealed containers made of glass or stainless steel, away from oxidizing agents and heat sources. Shelf life is typically 2–3 years when stored under recommended conditions. Spills should be contained using inert absorbents and disposed of following local regulations.
B2B Procurement Guide
When sourcing phenyl acetate, prioritize suppliers with certifications like ISO 9001 or GMP compliance to ensure quality consistency. Key specifications to verify include purity (≥98%), water content (<0.1%), and absence of heavy metals. Bulk purchases (drums or totes) often reduce costs, but sample testing is advised to confirm suitability for your application. Regional pricing varies; Chinese suppliers may offer competitive rates, while European sources emphasize traceability. Always request Safety Data Sheets (SDS) and technical bulletins for compliance documentation.
