Anwendungen & Verwendung
Beschreibung
Methoxyethene (MVE) is a colorless and flammable gas with a sweet and pleasant odor at room temperature. It is heavier than air and can diffuse to a relatively distant place at a lower place. MVE is soluble in ethanol, ether and acetone, but it is only slightly soluble in water. MVE is easily polymerized, so potassium hydroxide is often added as a polymerization inhibitor in the finished product.
Verwenden
Copolymers used in coatings and lacquers; modifier for alkyl, polystyrene, and ionomer resins; plasticizer for nitrocellulose and adhesives.
