Propylene Oxide as Organic Synthetic Intermediate CAS No.75-56-9

Product Introduction

Propylene Oxide (CAS:75‑56‑9, molecular formula C₃H₆O) is a high‑activity basic petrochemical intermediate produced by chlorohydrin method or co‑oxidation process. It appears as colorless transparent volatile liquid with mild ether‑like odor, freely miscible with water, ethanol, ether and most organic solvents. Featuring high ring‑opening reaction activity, it can react with alcohols, amines and water to generate various downstream derivatives. Strict quality control on purity, moisture and impurity indicators ensures stable batch consistency, compliant with global industrial raw‑material standards. It is widely applied for manufacturing polyether polyols, propylene glycol, propylene glycol ethers, non‑ionic surfactants and fine‑chemical intermediates fields.

Applications

★Polyurethane Raw‑Material Industry (Core Consumption Field): Main raw‑material for polyether polyols production. Polyether polyols are further processed into rigid & flexible polyurethane foam, thermal‑insulation materials, elastomers, adhesives and sealants, widely used in construction insulation, household refrigeration equipment, automobile interior parts.

★Fine‑Chemical & Surfactant Industry: Used to synthesize propylene glycol, propylene glycol ether series products, which serve as high‑boiling‑point solvents for water‑based coatings, printing inks and cleaning agents. It is also critical feedstock for non‑ionic surfactants, emulsifiers, demulsifiers for textile, pesticide and petroleum‑processing industries.

★Pharmaceutical & Daily‑Chemical Manufacturing: Intermediate for producing isopropanolamine series, applied for gas‑absorbing agents, pharmaceutical excipients and daily‑chemical auxiliary formulations. Derivatives can be used for humectants and emulsifiers in personal‑care products.

★Organic Synthesis & Other Related Fields: As reaction raw‑material for manufacturing propylene carbonate, synthetic lubricants and pesticide intermediates. Also used as low‑boiling‑point solvent for special resin formulations.
