Atmospheric degradation of industrial fluorinated acrylates and methacrylates with Cl atoms at atmospheric pressure and 298K was written by Rivela, Cynthia B.;Blanco, Maria B.;Teruel, Mariano A.. And the article was included in Atmospheric Environment in 2018.Electric Literature of C7H6F6O2 The following contents are mentioned in the article:
The gas-phase reaction of Cl atom with 2,2,2-trifluoroethylacrylate (k1), 1,1,1,3,3,3-hexafluoroisopropylacrylate (k2), 2,2,2-trifluoroethylmethacrylate (k3) and 1,1,1,3,3,3-hexafluoroisopropylmethacrylate (k4), have been investigated at 298K and 1atm using the relative method by gas chromatog. coupled with flame ionization detection (GC-FID). The values obtained are (in cm3 mol.-1 s-1): k1(Cl+CH2=CHC(O)OCH2CF3) = (2.41±0.57)×10-10, k2(Cl+CH2=CHC(O)OCH(CF3)2) = (1.39±0.34)×10-10, k3(Cl+CH2=C(CH3)C(O)OCH2CF3) = (2.22±0.45)×10-10, and k4(Cl+CH2=C(CH3)C(O)OCH(CF3)2 = (2.44±0.52)×10-10). Products identification studies were performed by solid-phase microextraction (SPME) method, with on-fiber products derivatization using o-(2,3,4,5,6-pentafluorobenzyl) hydroxylamine hydrochloride, coupled with gas chromatog. with mass spectrometry detection (GC-MS). Chloroacetone, trifluoroacetaldehyde and formaldehyde were observed as degradation products and a general mechanism is proposed. Addnl., reactivity trends and atm. implications are discussed. This study involved multiple reactions and reactants, such as 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3Electric Literature of C7H6F6O2).
1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Electric Literature of C7H6F6O2
