Abstract
1,1,4,4-Tetrakis(trifluoromethyl)butan-1,4-diol and 1,1-bis (trifluoromethyl)propanol-1 are prepared by reacting gaseous hexafluoroacetone and ethane in a transparent container in the presence of sunlight. The diol is a crystalline solid and the propanol-1 is a liquid. The diol is useful as a monomer in the field of polymer chemistry. That is, polymers such as polyurethans and polyesters which find many applications in the chemical industry can be made by reacting the proper material with the diol of this invention. The propanol-1 is useful as a plasticizer for polyurethans and other plastics.
