N. (Univ. Bradford, Bradford/West Yorkshire BD7 1DP, UK). J. Mol. Struct., 263, 11-20 (English) 1991. CODEN: JMOSB4. ISSN: 0022-2860. DOCUMENT TYPE: Journal CA Section: 23 (Aliphatic Compounds) Section cross-reference(s): 22 The prepn. of CCl3SO3H (I) from CCl3SO2Cl is reported and vibrational assignments made on the basis of Cs mol.Several substances with their cas registry numbers 2547-61-7 and 27153-10-2 may be metioned in this study. symmetry. Raman spectra of the pure acid and of its aq. soln. indicate that only partial dissocn. into trichloromethanesulfonate ions occurs in aq. soln.; in a 2 M aq. soln. of I a = 0.986 and Kc = 139 ± 18 mol dm-3. .
