摘要：

Low molecular weight oligomers from acid catalyzed condensation of 2-naphthalensulfonic acid and formaldeyde were obtained. Spectroscopic (NMR) studies of dinuclear mixture verified the presence of 5,5'- 8,8'- and 5,8'-methylenebis-2-naphthalensulfonic acid, with a predominance of products derived from 5-attack. Trinuclear product confirmed the presence of a linear structure of these condensate. Similar results were also obtained from dinuclear product separated from commercial product (Daxad 15-Grace). © 1990.
