摘要:
A benzyl vinyl ether represented by the following formula is hydrolyzed in the presence of a catalyst selected among Arrhenius acids and Lewis acids to obtain 3,3,3-trifluoropropionaldehyde. Subsequently, the 3,3,3-trifluoropropionaldehyde is oxidized with an oxidizing agent. Thus, 3,3,3-trifluoropropionic acid can be more advantageously produced than in conventional techniques from an inexpensive starting material.

摘要:
A method for forming a protective film of a fluorine-containing polymer composition excellent in smoothness and adhesiveness on a photoresist. Moreover, there is provided a means for removing the protective film without impairing the underlying photoresist. A polymer coating composition obtainable by dissolving a fluorine-containing polymer compound in a solvent comprising a fluorinated acetal having a specific structure is applied on a photoresist and dried to form a protective film. A fluorinated acetal having the specific structure is suitable as a solvent for being brought into contact with a fluorine-containing polymer film, peeling the film, and forming a photoresist or a lithographic pattern.
