二甲醇縮甲醛（Dimethoxymethane），是一種有機(jī)化合物，分子式是C3H8O2。
主要用于生產(chǎn)陰離子效換樹(shù)脂，也作溶劑和特種燃料。其溶解能力比乙醚、丙酮強(qiáng)，和甲醇和共沸混合物能溶解含氮量高的硝化纖維素。但由于其蒸氣有較強(qiáng)麻醉性，不宜作一般溶劑使用，通常作特殊聲合的溶劑。 還用于香料制造、生產(chǎn)人造樹(shù)脂，用作格利雅反應(yīng)和雷帕（合成）反應(yīng)的反應(yīng)介質(zhì)。

Dimethoxymethane is an organic compound with the molecular formula C3H8O2.
It is mainly used for the production of anion exchange resin, as well as solvent and special fuel. Its solubility is stronger than that of ether and acetone, and its mixture with methanol and azeotrope can dissolve nitrocellulose with high nitrogen content. However, due to its strong anesthetic properties, its vapor is not suitable for use as a general solvent, and is usually used as a solvent for special sound synthesis. It is also used in perfume manufacturing, production of artificial resin, and as a reaction medium for Grignard reaction and Rapa (synthesis) reaction.
This document specifies the product classification, requirements, test methods, inspection rules, marks and labels, packaging, transportation, storage and safety of formaldehyde dimethyl acetal (methylal) for industrial use. This document is applicable to formaldehyde dimethyl acetal (methylal) products synthesized from formaldehyde and methanol.
