Second dissociation constant of succinic acid from 0-degrees to 50-degrees-C

Abstract

copper wo uld b e distributed on the leather than, would b e jf th e d ye bath was applied only to t h e fur surface. Another r eason the seal fur did not deteriorate as much as migh t b e expected from the copper content, as compared t o t h e Karakuls, may be that the oil t annage is inher en tly more resistant than the pre-dominan tly alum-type dressing of the lambskins. The r ate wi th which the metal salts ar e leached or r emoved from th e lambskin pel ts holds no relationship to th e ext en t of deterioration. In other words t h e degree of th e fixation of m etal salts do es no t follow th e aging. The r es ul ts of water extraction of t h e metal salts from t h e skins are shown in table 7. TAR LE 7.
