Abstract: The production process of s-trioxane is introduced and the influencing factors on the purity of s-trioxane are investigated.Contents of light and heavy components in s-trioxane are reduced effectively through adopting new washing method with alkaline water and using new technology for removing heavy components from s-trioxane.The purity of s-trioxane rises by 0.6%,which meets greatly the needs of polymerization.
