    摘要: Preparation of 2-chloromethyl-1,3-polyfluoro-2-propanols by subjecting a mixture of a 2-methyl-1,3-polyfluoro-2-propanol, or a 2-(mono or dichloromethyl)-1,3-polyfluoro-2-propanol and chlorine to the action of a broadband of ultraviolet light in the wavelength range between about 2,000* A. and about 3,600* A. at a temperature between about 10* C. and about 200* C. The resulting compounds and their fluorinated derivatives are useful as fumigants against insects.
