Abstract

The present application belongs to the technical field of synthesis of fluorine-containing fine chemicals and specifically relates to an oxa-hydrofluoroether compound and a synthesis method and a use thereof. An oxa-hydrofluoroether compound, having a structure as shown in Formula (1): <img class="EMIRef" id="114dc869-d79d-4c1c-84ef-80a8ba59ef5b-ia01" /> wherein, R<f> is F or CF<3>; R is methyl or ethyl; n is an integer of 1-3. For the oxa-hydrofluoroether compound disclosed in the present application, due to the embedding of oxygen atoms in the fluorocarbon chain structure, the fluorine-containing segments of hydrofluoroether are more diversified, such that the structure is no longer limited to a perfluorocarbon chain structure. In such an oxa-hydrofluoroether compound, the oxygen atoms play a role in reducing the surface tension, and the more oxygen atoms the oxa-hydrofluoroether compound contains, the lower the surface tension. Compared with other hydrofluoroether solvents, the oxa-hydrofluoroether compound exhibits stronger permeability and better cleaning performance. Due to the embedding of oxygen atoms into the fluorocarbon chain structure and the presence of branched fluorocarbon segments, the oxa-hydrofluoroether compound is more readily degradable, thereby improving environmental friendliness.
