摘要： An electrolyte for a non-aqueous electrolyte battery includes a non-aqueous organic solvent and at least lithium hexafluorophosphate as a solute, characterized by further including 10 to 1000 mass ppm of a phosphorus-containing acidic compound and 0.01 to 10.0 mass % of a difluorophosphate. The phosphorus-containing acidic compound is preferably at least one selected from the group consisting of HPF6, HPO2F2, H2PO3F and H3PO4. By the use of such an electrolyte, it is possible to provide the non-aqueous electrolyte lithium battery capable of maintaining high discharge capacity even after repeated charge/discharge cycles under a high temperature environment.

摘要： As shown by the following reaction formula, disclosed is a fluorine-containing hydroxyaldehyde production method, including the step of obtaining a fluorine-containing hydroxyaldehyde represented by the general formula (1) by reacting a fluorine-containing ketone represented by the general formula (4) and an aldehyde represented by the general formula (5) in the presence of an organic base selected from a heterocyclic compound which contains a nitrogen atom in its ring or a tertiary amine. By this production method, it is possible to obtain the fluorine-containing hydroxyaldehyde in a high yield. Furthermore, it is possible to easily obtain in high yields a fluorine-containing propanediol, which is a derivative of this fluorine-containing hydroxyaldehyde, and a fluorine-containing alcohol monomer by using the same.
