Bis-diol monoalkyl ether formaldehyde preparation method

The invention discloses a bis-diol monoalkyl ether formaldehyde preparation method. The bis-diol monoalkyl ether formaldehyde can be prepared by the steps: utilizing methylene diethyl ether and diolmonoalkyl ether as raw materials and performing transacetalation under the catalysis of phosphotungstic acid. According to the preparation method disclosed by the invention, the bis-diol monoalkyl ether formal is synthesized from a phosphotungstic acid catalyst; the catalyst has the advantages of small use amount, high catalytic activity, small corrosion to equipment and easiness in being separated from products; recycling the catalyst is achieved; the preparation method is a high-efficiency, green and environment-friendly production method. The methylene diethyl ether is utilized to replace formaldehyde as the raw material, so that pollution of the formaldehyde to the environment and harm of the formaldehyde to the human body are greatly reduced; wastewater emission is reduced, product quality is improved, and a green chemistry idea is met.
