Abstract

It has been shown that, at a temperature of 75°C, 1,3,5-trioxane obtained by the liquid-phase method in the presence of a homogeneous catalyst partially decomposes with the formation of free formaldehyde, paraformaldehyde, and formic acid. A number of stabilizers for the thermal-oxidative degradation of 1,3,5-trioxane have been proposed and their effectiveness has been compared. The most effective additives were selected and their concentrations were determined, which provide the minimum amount of by-product formation under the indicated conditions.

1,3,5-三恶烷稳定工艺的特点

摘要

已经表明，在75℃的温度下，通过液相法在均相催化剂存在下获得的1,3,5-三恶烷部分分解，形成游离甲醛、多聚甲醛和甲酸。已经提出了多种用于 1,3,5-三恶烷热氧化降解的稳定剂，并对它们的有效性进行了比较。选择最有效的添加剂并确定其浓度，从而在指定条件下将副产物的形成量降至最低。
