Method for synthesizing trioxymethylene by cyclic reaction of formaldehyde aqueous solution catalyzed by ionic liquid

The invention provides a method for synthesizing trioxymethylene by cyclic reaction of a formaldehyde aqueous solution catalyzed by ionic liquid. The method comprises the following steps: carrying out distillation reaction to the reactants formaldehyde aqueous solution and ionic liquid under atmospheric conditions at 97-102 DEG C so as to synthesize trioxymethylene; in percentage by weight, the addition amount of the formaldehyde aqueous solution is 30-80wt%, the addition amount of the ionic liquid is 0.1-6wt%, and water accounts for all the remaining percentage; and the ionic liquid is a liquid composed of anions and cations, wherein the anions are p-ClPhSO3-. The ionic liquid formed by 4-chlorobenzene sulfonate as anion is used as the catalyst of the method so as to synthesize trioxymethylene by cyclic reaction of formaldehyde; thus, the catalyst is high in catalytic activity and small in dosage; moreover, the reacted trioxymethylene is relatively high in concentration while the contents of the byproducts, including methanol, formic acid and the like, are low; and the reacted trioxymethylene is also good in selectivity.
