邻羟基苯甲醛的合成及应用研究进展

Progress of Study on Synthesis and Application of O-Hydroxybenzaldehyde

介绍了目前邻羟基苯甲醛的合成工艺及应用。从合成原料的角度对邻羟基苯甲醛的合成方法进行了比较,Reimer-Tieman法因其操作简单、原料廉价易得等优点一直被使用;而邻甲酚直接氧化法产品收率和纯度高、环境污染小、原料廉价易得,在环保要求日趋严格的情况下,更具竞争优势,是今后极具发展前途的合成方法。

The synthesis process and application of o- hydroxybenzaldehyde are introduced. The synthesis methods of o - hydroxybenzaldehyde were compared from the perspective of the synthesis of raw materials. Among them, Reimer- Tieman method has been used for its simple operation and cheap raw materials. And direct oxidation of o - cresol high product yield high purity and little raw materials, and has more competitive advantage under the requirements, which is the future nromising svnthesis method. environmental pollution, with cheap accessible increasingly stringent environmental protection
