The rate coefficient of the reaction of dimethoxymethane with OH radicals was determined in a slow-flow reactor with pulsed laser photolysis/laser-induced fluorescence technique. Temperatures ranged from 297–570 K at nominal pressures of 2, 5, and 10 bar (bath gas: argon). The very weak temperature dependence of the obtained rate coefficient can be expressed as: k₁(T) = (2.9 ± 0.2) × 10^–12 exp[(126 ± 30)/T] cm³ s^–1. A significant pressure dependence was not observed. The results are in very good agreement with literature data for temperatures up to 370 K whereas differences occur at T > 400 K.

二甲氧基甲烷与羟基自由基的反应：在高于296 K的温度，2、5和10 bar的压力下进行的实验动力学研究

用脉冲激光光解/激光诱导荧光技术在慢流反应器中确定二甲氧基甲烷与OH自由基的反应速率系数。在标称压力为2、5和10 bar（浴气体：氩气）下，温度范围为297–570K。所得速率系数的非常弱的温度依赖性可以表示为：k ₁（T）=（2.9±0.2）×10 ^–12 exp [（126±30）/ T ] cm ³ s ^–1。没有观察到明显的压力依赖性。该结果与温度高达370 K的文献数据非常吻合，而在T > 400 K时会出现差异。
