一种提纯2,2-二甲氧基乙醛的方法
摘要：
本发明公开了一种提纯2,2‑二甲氧基乙醛的方法，属于精细化学品的分离提纯技术领域。本方法以2,2‑二甲氧基乙醛反应液为初始原料，经常压蒸馏，再加水进行萃取精馏，可得到高纯度的2,2‑二甲氧基乙醛溶液，纯度高于98％。具有操作工艺简单，提纯产品纯度高的特点。
摘要（英）：

The invention discloses a method for purifying 2,2-dimethoxy acetaldehyde, and belongs to the technical field of separating and purifying fine chemicals. According to the method, a 2,2-dimethoxy acetaldehyde reaction solution is used as an initial raw material and subjected to normal pressure distillation, then water is added, and extractive distillation is conducted to obtain a high-purity 2,2-dimethoxy acetaldehyde solution, wherein the purity is higher than 98%. The method has the advantages that the operation process is simple, and the purified product is high in purity.
