Use of sulfated substances to grease leather |
| abstract |
Sulphured substances useful for stuffing leather are obtained by reacting esters (a) of monohydric or polyhydric alcohols with 1 to 24 C atoms and fatty acids with 1 to 30 C atoms, the sum of C atoms in the alcohol and fatty acid components of the esters being equal to at least 19, with a sulphuring reactive (b), then by neutralising them. As sulphuring 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 40 %by weight. The esters (a) used are preferably at least partially ethylenically unsaturated in relation to their alcohol and/or fatty acid components. |
