Abstract: PROBLEM TO BE SOLVED: To provide a satisfactory process order even when an order of manufacturing plan is collapsed. SOLUTION: This manufacturing control method is executed according to the manufacturing plan and in the manufacturing control method of separable chemical processes to be used for manufacturing plural generated products A, B, C at a plurality of stages 1, 2, 3, a measured value based on an operation parameter at least one stage of the stages 1, 2, 3 is recorded, monitored, a signal is generated when the measured value exceeds a limit value, the manufacturing plan is calculated again, based on the signal and the processes, are executed, based on a new manufacturing plan of the stages 1, 2, 3.

Abstract: The invention relates to a method for producing trioxane by the trimerization of formaldehyde in an aqueous acidic solution and by subsequently separating out trioxane from a mixture (trioxane raw product) essentially consisting of trioxane, water and formaldehyde. The invention is characterized in that: a) the trioxane raw product from the trimerization is distilled; b) the trioxane is crystallized out; c) is separated out from the mother liquor; d) is subsequently melted, and; e) additional byproducts are removed by distillation.

Abstract: According to the invention, the production of oxymethylene homo- or co-polymers from an aqueous solution of formaldehyde and polyoxymethylene glycols is achieved, whereby 1) in a separation stage, water and formaldehyde are at least partly separated out from the aqueous solution, such that a phase containing polyoxymethylene glycols is obtained, in which the molar ratio of polyoxymethylene glycols to formaldehyde is greater than 1:0.6 and 2) the polyoxymethylene glycols obtained in stage 1) are reacted in the presence of polycondensation catalysts with abstraction of water to give oxymethylene homo- or co-polymers.
