Description

1. Description
Propylene oxide is a colorless, low-boiling and highly volatile liquid with a sweet, ether-like odor. It is highly flammable and reactive, and storage and unloading areas must be appropriately designed and monitored.

2. Applications

Polyether Polyols
The polyurethane industry is the largest consumer of propylene oxide.
It utilizes polyether polyols made by reacting propylene oxide alone or in combination with other alkylene oxides. The most common initiators are polyols or polyamines such as glycerine,glycols, pentaerythritol, ethylenediamine, toluenediamine, sucrose, sorbitol. Polyether polyols are reacted with various diisocyanates to form polyurethane foams and
resins.

Propylene glycols
Reaction of propylene oxide with water leads to monopropylene glycol (MPG) with subsequent reactions leading to di-(DPG), tri-(TPG). Propylene glycols are used in a wide range of applications, including use as raw materials for unsaturated polyester resins, humectants in pharmaceuticals, cosmetic and food, heat transfer fluids, antifreezes and aircraft deicers.

Propylene glycol ethers
Propylene glycol ethers are formed by base catalyzed reaction of PO with alcohols like methanol, ethanol, propanol, butanol or phenol. Subsequent reaction with additional PO leads to the corresponding di, tri- and higher glycol ethers.
Propylene glycol ethers are used as solvents and coupling agents in paints and in the production of coatings, resins and cleaners.

Other propoxylated derivatives
Reaction of propylene oxide with phosphorous compounds yields flame retardants used, for example, in polyurethane foams, textiles and flooring materials. Propoxylated carbohydrates like cellulose and starch are used in applications in the constructions, paints, food and pharmaceutical industries.
