产品说明

一般描述

3,4-二甲基苯甲醛 (3,4-DMB) 是一种苯甲醛衍生物。为三甲苯的 OH 自由基引发氧化降解产物。3,4-DMB 与 OH 自由基气相反应的速率系数为 24.6±4.0 × 10 ^-12 cm ³ 分子 ^-1 s ^-1。本文报道了基于 FT-IR、FT-Raman 和密度泛函理论 (DFT) 从头计算的 3,4-DMB 的振动分析。它是在使用 ZSM(沸石 Socony Mobil)-5 基催化剂将糠醛转化为汽油系列燃料的过程中作为中间体形成的。

应用

3,4-二甲基苯甲醛可用于合成 3,4-二甲基甲卡西酮 (DMMC) 和 3,4-二甲基-二亚苄基山梨醇。
