发明名称 Verwendung sulfierter Substanzen zur Fettung von Leder
摘要 Sulphited substances useful for stuffing leather are obtained by reacting esters (a) of monohydric or polyhydric alcohols with 1 to 24 C atoms and dicarboxylic acids with 2 to 24 C atoms, the sum of C atoms in the alcohol and fatty acid components of the esters being equal to at least 16, with a sulphiting reactive (b), then by neutralisation. As sulphiting reactive (b) a combination of at least one organic sulphonic acid (b1) and sulphuric acid (b2) is used, the proportion of sulphuric acid in relation to the sum of organic sulphonic acid and sulphuric acid amounting to 0.5 to 80 % by weight.
