Abstract:
Disclosed is a method for preserving an α,α-difluoroacetaldehyde alkyl hemiacetal of the following formula in a gas-liquid state having gas and liquid phases in a closed container under an atmosphere of oxygen (O 2 ) or inert gas, characterized by: controlling the oxygen concentration of the gas phase in the container to be 5000 ppm or lower; and then storing the α,α-difluoroacetaldehyde alkyl hemiacetal in the container under light-shielding conditions where R 1  represents an alkyl group or a substituted alkyl group. It is possible by this method to suppress conversion of the α,α-difluoroacetaldehyde alkyl hemiacetal to difluoroacetic acid over a long term.

Claim (Index 4):
The method according to  claim 3 ,\n wherein, in the third step, the storing is carried out in a temperature range of \u221250\u00b0 C. to 80\u00b0 C.
