Soluble in water (18 ℃ when 17.2g/100ml, 25 ℃ when 21.1g/100ml), alcohol, ether, acetone, chlorinated hydrocarbons, aromatic hydrocarbons and other organic solvents, slightly soluble in petroleum ether, pentane. Form an azeotropic mixture with water, the boiling point of 91.4 ℃, containing about 70% (g / g) of the three six-ring oxygen. Acid aqueous solution can be gradually depolymerization, but not by alkaline depolymerization. Non-aqueous formaldehyde that can be converted into a small amount of strong acid monomer, the conversion speed is determined by the concentration of acid. The relative density of 1.17. M.p. 64 ℃.

Trioxymethylene Explosive Limit: 3.6 ~ 28.7 (vol) Edit this paragraph the main purposes purposes: as a plastic polyoxymethylene and other chemical intermediates,f50 2013, and used as a disinfectant, mainly for the production of epoxy resins, bisphenol A The catalyst is cosmetics perm lotion and depilatory main raw material, can also be used for synthesis of transparent plastic and organic antimony, tin, and other organic basic raw material for heat stabilizer isooctyl thioglycolate, which is a test reagent products of iron, molybdenum, silver, tin and other metal ions sensitive reagents. Is an important organic chemical raw materials, can also be done on the copper sulfide ore and iron sulfide minerals inhibitors. The production method can be edited paragraph 2% to 5% sulfuric acid, 60% aqueous formaldehyde by continuous distillation, the residue was extracted with benzene and then distilled.

trioxane

under certain conditions, can also generate a tetramer of formaldehyde, mp 112 ℃, boiling point 175 ℃. Three and four POM POM under the action of an acid, can be re-decomposed into formaldehyde, formaldehyde so they are a special form of commodities. In the production of a phenolic resin in order to control the amount of formaldehyde, trioxane has been used as the starting material.
