Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A polymerizable trioxane composition comprising 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 which is a uniform solution of trioxane in an aromatic hydrocarbon solvent. 2. The trioxane composition according to claim 1 , wherein the alkaline organic compound is at least one compound selected from the group consisting of a tertiary amine compound having an alcoholic hydroxy group in the molecule thereof, a dithiocarbamate compound, and an alkyl- or arylphosphine compound. 3. The trioxane composition according to claim 1 , wherein the alkaline organic compound is triethanolamine. 4. The trioxane composition according to claim 1 , wherein the antioxidant is at least one compound selected from the group consisting of a phenolic compound and a hindered phenol compound; and wherein the amount of the antioxidant contained is 10 to 500 ppm, based on the trioxane. 5. The trioxane composition according to claim 1 , wherein the content of the trioxane in the trioxane composition, excluding the solvent, is 95% or more. 6. A method for storing a trioxane composition, the method comprising maintaining the trioxane composition according to claim 1 in a liquid state. 7. A method for storing a trioxane composition, the method comprising maintaining the trioxane composition according to claim 2 in a liquid state. 8. A method for storing a trioxane composition, the method comprising maintaining the trioxane composition according to claim 3 in a liquid state. 9. A method for storing a trioxane composition, the method comprising maintaining the trioxane composition according to claim 4 in a liquid state. 10. A method for storing a trioxane composition, the method comprising maintaining the trioxane composition according to claim 5 in a liquid state. 11. The trioxane composition of claim 1 , wherein the aromatic hydrocarbon solvent is selected from the group consisting of benzene, toluene, xylene and mixtures thereof.
