The generation of solid para-formaldehyde is blocked when gas is dissolved in liquid alcohol. The ratio of trioxane to paraformaldehyde can be adjusted. Crystals are grown from over-frozen liquid in scraping-surface freezers. The same crystals continuously release suspension containing trioxane crystal, trioxane crystals are separated from the same suspension. Thus trioxane with high purity and high yield can be separated.
