Synthesis And Structure of Methylal:
Methylal can be manufactured by oxidation of methanol or by the reaction of formaldehyde with methanol.
In aqueous acid, Methylal is hydrolyzed back to formaldehyde and methanol.
Due to the anomeric effect, Methylal has a preference toward the gauche conformation with respect to each of the C–O bonds, instead of the anti conformation.
Since there are two C–O bonds, the most stable conformation is gauche-gauche, which is around 7 kcal/mol more stable than the anti-anti conformation, while the gauche-anti and anti-gauche are intermediate in energy.
Since Methylal is one of the smallest molecules exhibiting this effect, which has great interest in carbohydrate chemistry, Methylal is often used for theoretical studies of the anomeric effect.
Reagent In Organic Synthesis:
Another useful application of Methylal is to protect alcohols with a methoxymethyl (MOM) ether in organic synthesis.
Methylal can be activated with phosphorus pentoxide in dichloromethane or chloroform.
This method is preferred to the use of chloromethyl methyl ether (MOMCl).
Phenols can also be MOM-protected using Methylal, p-toluenesulfonic acid.
Alternatively, MOMCl can be generated as a solution by treating Methylal with an acyl chloride in the presence of a Lewis acid catalyst like zinc bromide:
MeOCH2OMe + RC(=O)Cl → MeOCH2Cl + RC(=O)(OMe)).
Unlike the classical procedure, which uses formaldehyde and hydrogen chloride as starting materials, the highly carcinogenic side product bis(chloromethyl) ether is not generated

Methylal is produced through the reaction of methanol and formaldehyde in the presence of concentrated sulfuric acid.
The resultant methylal is distilled, and unreacted methanol is separated from the product for recycling to obtain methylal with a content of 85% or more.
