Armour acetals is a kind of natural gas and coal chemical industry important derivative products, is an environment-protecting organic solvent, in cleaner, paint, diesel performance additives etc widely application. Catalytic rectification preparation armour acetals technology at present domestic has not been formed mass industrial production, have certain development application value.
This paper determines the catalytic rectification legal system for a number of process parameters acetals, through the choice of catalysts and the dosage, batching scale, reaction temperature and pressure of feedrate and reflux ratio, experimental study of optimal process conditions: ingredients than methanol and formaldehyde for the molar ratio of 1:1 ~ 45.16% prestressing, reaction temperature 40 to 60 ℃, catalyst share of total volume of 30%, distillation tower, catalyst layers and the bottom and reaction temperature temperature respectively is 30 ~ 50 ℃, 50 ~ 60 ℃ and 75 ~ 90 ℃, draw the tower 2kg/cm3, less stress than 3.5 kg/thetower bottom pressure cm3 and tower fractions out and backflow of amount of substance ratio control in 1:1 ~ 1.4:1. In optimal parameters under conditions of repeatability of experiment results show good.希望能帮到你

Methylal is a significant natural gas and coal chemical derivatives, is an environmentally friendly organic solvents, detergents, paints, diesel modified additives and other fields are widely used. Preparation of catalytic distillation process methylal not yet formed a large-scale domestic industrial production, development and application of a certain value. We have identified a catalytic distillation methylal prepared a number of process parameters on catalyst selection and dosage, the proportion of ingredients, reaction temperature and pressure of each segment and return the best ratio of experimental research conditions: mixture ratio of methanol and formaldehyde molar ratio of 1:1 ~ 2:1,Pre-reaction temperature is 40 ~ 60 ℃, catalyst amount of the total volume of 30% of the distillation tower, reaction temperature, catalyst layer and bottom temperatures were 30 ~ 50 ℃, 50 ~ 60 ℃ and 75 ~ 90 ℃, was the top pressure is less than 2kg/cm3, bottom and top pressure is less than 3.5kg/cm3 distillate and the return of control in a 1:1 molar ratio of ~ 1.4:1. Parameters at the optimum conditions Experimental results show good repeatability.
