ASSESSMENT OF POLYFUNCTIONAL MACROCYCLIC COMPOUNDS IN SOLUTION BY CRYOSCOPIC METHOD
Abstract and keywords
Abstract (English):
Sintezirovany mezo-tetrakis(1’-metil-pirid-4-il)porfirin tetratozilat i mezo-tetrakis(1’-metil-karboksimetilpirid-4-il)porfirin tetrabromid. Porfirin-ligandy oharakterizovany metodami elektronnoy i 1H YaMR spektroskopii. Opredeleno ponizhenie temperatury zamerzaniya (ΔTzam) vodnyh rastvorov porfirinov, a takzhe model'noy N-metil-piridinievoy soli (1-metil-piridiniy iodid). Poluchennye eksperimental'nye znacheniya ΔTz ispol'zovany pri opredelenii izotonicheskogo koefficienta. Poluchennye rezul'taty svidetel'stvuyut o tom, chto v ukazannoy oblasti koncentraciy v razbavlennyh rastvorah, soedineniya prakticheski polnost'yu dissociirovany.

Keywords:
