PREPARATION METHOD OF DIMETHOXYMETHANE:
methanol and formaldehyde were synthesized in a synthetic tower using concentrated sulfuric acid as a catalyst, and the fraction controlled at the top temperature of 41. 5-42 ℃ was formaldehyde.
PRODUCTION METHOD OF DIMETHOXYMETHANE:
methanol and formaldehyde were reacted in the synthesis column under the catalysis of concentrated sulfuric acid.
The resultant Dimethoxymethane is distilled out from the tower where the temperature is controlled at 41.5-42 ° C., and unreacted methanol is separated from the product for recycling to obtain Dimethoxymethane with a content of 85% or more. 37% of methanol and of formaldehyde are consumed per ton of product.
The impurities in the product Dimethoxymethane are mainly methanol and formaldehyde.
When higher purity is required, formaldehyde can be removed by oxidation with alkaline hydrogen peroxide, and methanol can be removed by distillation with sodium metal.
PRODUCTION OF DIMETHOXYMETHANE:
Dimethoxymethane is produced through the reaction of methanol and formaldehyde in the presence of an acidic catalyst.
Dimethoxymethane is generally known that Dimethoxymethane can be produced in the presence of sulfuric acid.
However, sulfuric acid results in severe corrosion as well as some difficulties in waste disposal.
Conventionally, the Dimethoxymethane production is of batch process in which reaction and product isolation are carried out separately.
OTHER STORAGE CONDITIONS OF DIMETHOXYMETHANE:
Dimethoxymethane should be stored in an area without drain or sewer access.
Dimethoxymethane should be stored away from direct sunlight.
Dimethoxymethane should be stored in tightly closed containers.
Dimethoxymethane should be stored away from incompatible substances.
Dimethoxymethane should be kept away from heat, sparks, and flame.
Dimethoxymethane is an important raw material and an excellent solvent in industry.
Dimethoxymethane should be kept separated from strong oxidants and strong bases.
Plus, Dimethoxymethane should be stored in a cool, dry, and well-ventilated facility.
