The atmospheric fate of 1,3-dioxolane is assessed by measuring the OH and Cl initiated gas-phase oxidation kinetics, and exploring their mechanistic pathways. Absolute OH reaction rate coefficient of 1,3-dioxolane using laser photolysis-laser induced fluorescence technique is found to be (1.27 ± 0.03) × 10^–11 cm³ molecule⁻¹ s⁻¹ at 298 ± 2 K and it is in good agreement with the measured relative value of (1.13 ± 0.12) × 10^–11 cm³ molecule⁻¹ s⁻¹, using gas-chromatography. Relative value of Cl reaction rate coefficient with 1,3-dioxolane is found to be (1.64 ± 0.60) × 10^–10 cm³ molecule⁻¹ s⁻¹. The tropospheric lifetime of 1,3-dioxolane is calculated to be about 22 h under ambient conditions. Interestingly, it reduces to about 8 h near marine boundary layer, where Cl reaction takes over the OH reaction. Such a short lifetime with respect to reaction with OH and Cl suggests the atmospheric impact of 1,3-dioxolane to be local. Formic acid, ethylene carbonate, and 1,2-ethanediol monoformate are observed as stable products in OH as well as Cl oxidation. 1,3-dioxolane may contribute as one of the sources of formic acid in the atmosphere. Theoretical calculations for the OH-initiated hydrogen abstraction of 1,3-dioxolane revealed that the reaction follows an indirect path through the formation of pre- and post-reaction complexes at entrance and exit channels, respectively with the lowest barrier height of 3.5 kcal/mol. Photochemical ozone creation potential of 1,3-dioxolane is calculated.

通过测量 OH 和 Cl 引发的气相氧化动力学并探索其机理途径，评估 1,3-二氧戊环在大气中的归宿。激光光解-激光诱导荧光技术得到的1,3-二氧戊环的绝对OH反应速率系数在298±2K时为(1.27±0.03)×10 ^–11 cm ³ molecule ⁻¹  s ⁻¹，处于良好状态与使用气相色谱法测得的 (1.13 ± 0.12) × 10 ^–11 cm ³分子⁻¹  s ⁻¹的相对值一致。Cl 与 1,3-二氧戊环的反应速率系数的相对值为 (1.64 ± 0.60) × 10 ^–10 cm ³分子⁻¹  s ⁻¹. 在环境条件下，1,3-二氧戊环的对流层寿命经计算约为 22 小时。有趣的是，它在海洋边界层附近减少到约 8 小时，其中 Cl 反应接管了 OH 反应。与 OH 和 Cl 反应的如此短的寿命表明 1,3-二氧戊环的大气影响是局部的。甲酸、碳酸亚乙酯和 1,2-乙二醇单甲酸酯在 OH 和 Cl 氧化中被观察为稳定产物。1,3-二氧戊环可能是大气中甲酸的来源之一。OH 引发的 1,3-二氧戊环夺氢反应的理论计算表明，反应遵循间接路径，通过在入口和出口通道处形成反应前和反应后复合物，最低势垒高度分别为 3.5 kcal/摩尔。
