Abstract
The present invention provides a trioxane composition which comprises trioxane as a main component, an antioxidant, and at least one alkaline organic compound selected from the group consisting of an amine compound having an alcoholic hydroxy group in the molecule thereof, a thiocarbamate compound, and an organophosphorus compound, wherein the amount of the alkaline organic compound contained is 0.01 to 10 ppm, based on the trioxane, and wherein the trioxane composition is a liquid.
Claims5
A method for storing a polymerizable trioxane composition, the method comprising:
- providing a polymerizable trioxane composition comprising trioxane as a main component, an antioxidant, and an amine compound having an alcoholic hydroxy group in the molecule thereof, wherein the amount of the amine compound contained is 0.01 to 10 ppm, based on the trioxane;
- maintaining the polymerizable trioxane composition in a molten state for a period of time between 0.1 hour and 30 days;
- and,
- at the expiration of the period of time, subjecting the polymerizable trioxane composition to purification treatment for removing impurities.
