PRODUCTION METHOD OF METHYLAL:
methanol and formaldehyde were reacted in the synthesis column under the catalysis of concentrated sulfuric acid.
The resultant methylal 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 methylal with a content of 85% or more. 37% of methanol and of formaldehyde are consumed per ton of product.
The impurities in the product methylal 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 METHYLAL:
Methylal is produced through the reaction of methanol and formaldehyde in the presence of an acidic catalyst.
Methylal is generally known that methylal 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 methylal production is of batch process in which reaction and product isolation are carried out separately.
OTHER STORAGE CONDITIONS OF METHYLAL:
Methylal should be stored in an area without drain or sewer access.
Methylal should be stored away from direct sunlight.
Methylal should be stored in tightly closed containers.
Methylal should be stored away from incompatible substances.
Methylal should be kept away from heat, sparks, and flame.
Methylal is an important raw material and an excellent solvent in industry.
Methylal should be kept separated from strong oxidants and strong bases.
Plus, Methylal should be stored in a cool, dry, and well-ventilated facility.
