PROCESS FOR PRODUCING FLUORINATED ACRYLIC ESTER
A mixture of fluorine-containing acrylic esters represented by CF3(CF2)nCH2CH2OCOCR1=CH2 wherein R1 is a hydrogen atom, a methyl group or a halogen atom and "n" is an integer of at least zero is subjected to distillation under such conditions that the esters are not polymerized, so as to give a mixture of the esters with a less content of impurities (that is, olefins represented by CF3(CF2)nCH=CH2 and alcohols represented by CF3(CF2)nCH2CH2OH) at a high yield.

SYNTHESIS OF FLUORINE-CONTAINING NITRO COMPOUNDS
Fluoronitro alkanes (5a and 5b), possesing the structure -CF2CH2CH(NO2)2, were synthesized from 1-iodo-1H,1H,2H,2H-perfluoroalkanes by displacing the iodide with sodium nitrite and then oxidatively nitrating the 1-nitro-1H,1H,2H,2H-perfluoroalkanes with tetranitromathane.Reaction with formaldehyde gave the dinitroalcohols, 6a and 6b. α,ο-diiodoperfluoroalkames (1c and 1d) were similarly converted to tetranitrofluoroalkanes (5c and 5d), characterized as tetranitrodiols 6c and 6d, and Michael adducts with methyl acrylate, 7c and 7d.
