I solns., useful as monomer in copolymn., stabilizer for polymer dispersions, or brightener in Ni electroplating, were obtained by spray-drying or spray-evapn. in a steam of air at 50-7*. Thus, 175 kg 33.77o I soln./hr (iodine no. 58.4, contg. 1.3% NaaSOj) was spray-dried at 27 atm gage in 2000 std. mJ hot (2C0") air/hr by using a 1-component nozzle to give 50* hot I contg. 5% HjO and 3.65% NajSOi and of grain size 10-300 pm, bulk d. 880 g/1., and iodine no. 165.5. 30723r Flame-retardant compositions. Kuehn, Erich (Atlas Chemical Industries, Inc.) U.S. 3,700,739 (Cl. 260/613R; C 07c), 24 Oct 1972, Appl. 728,913, 14 May 1968; 9 pp. Division of U.S. 3,644,599 (CA 75;154826e). Fire-retardant polyurethane foams were prepd. using the polyols I (R - Et, Bu, CHjCHtCHj, CHjCHBrCH_.Br; R' = Br, Cl) and II(R = Et, CH?CH:CHj, CHjCHBrCHjBr). Condensation of 3-halo-l,2-= propanediol and l,3-dihalo-2-propanol with a tetrahalo hisphenol A and treatment of the condensate with a phosphite gave I. Treatment of 2 phenols with a chlorophenol, HCHO, and a phosphite gave II.

After heating the mixt. at 130-90" and adding a water-sepn. aid, salt and org. contamination of the esters was decreased by washing and decanting at 150-9073-20 bars (rather than at 60-100*/! atm according to prior-art processes). Thus, a feedstream contg. bis[2-ethylhexyl) phthalate [117-81-7), 2-ethylhexanol, 2-ethylhexyl H phthalate, and 2-ethylhexyl H sulfate was fed at 20" to a column, where it was emulsified with aq. NajCOi at 179-83% 15 bars, and transferred to a decanting vessel contg. water, and the mixt. cooled to 98-100*. Aik. analysis of the sepd. phases showed a sepn. coeff. of 7950 compared to 41 for a conventional sepn. 30725t Acrylonitrile polymer dopes.
