Abstract The atmosphere contains 21% oxygen, the inquiry experiment of creating an oxygen-free environment to eliminate the interference of oxygen often appear in high school chemistry teaching. Some people put forward the method of isolation of oxygen by organic solvent, this article conducted the research from the dissolution theory and experiment, confirmed that the organic solvent could not isolate oxygen.
