Chemische Eigenschaften

Polypropylene glycol is a transparent, colorless to light yellow viscous liquid. It is classified into three types based on its average molecular weight: 425, 1025, and 2025. It is non-volatile and non-corrosive. The lower molecular weight polymer is soluble in water, while the higher molecular weight variants are only slightly soluble in water but are soluble in oils, many hydrocarbons, aliphatic alcohols, ketones, esters, and similar solvents. The hydroxyl groups at both ends of the molecule can undergo esterification to form monoesters or diesters. The monoesters function as non-ionic surfactants. Polypropylene glycol can also react with alcohols to form ethers. Additionally, it serves as a solvent for vegetable oils, resins, and paraffin.

Verwenden

Hydraulic fluids, rubber lubricants, antifoam agents, intermediates in urethane foams, adhesives, coatings, elastomers, plasticizers, paint formula- tions, laboratory reagent.

Definition

ChEBI: Poly(propylene glycol) is a macromolecule composed of repeating propyleneoxy units. It is a hydroxypolyether and a poly(ether) macromolecule.

Allgemeine Beschreibung

Colorless liquid that is odorless or has a mild sweet odor. May float or sink in water.

Reaktivit?t anzeigen

Poly(propylene glycol) is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

Health Hazard

The compound has a very low toxicity; few, if any, symptoms will be observed. Contact of liquid with eyes causes slight transient pain and irritation similar to that caused by a mild soap.

Sicherheitsprofil

Poison by intraperitoneal and intravenous routes.When heated to decomposition it emits acrid smoke and irritating fumes.
