Tanning with tris(hydroxymethyl)nitromethane and a polyhydric phenol |
| abstract |
A process for tanning skins in which skins are first impregnated and drummed at a pH range of 4.5 to 4.7 in a buffered aqueous solution containing tris(hydroxymethyl)nitromethane and a polyhydric phenol such as resorcinol, catechol, hydroquinone, pyrogallol and phloroglucinol. During the operation the pH of the tanning solution is adjusted to the range of 8.0 to 8.5 and the skins drummed until tanned. Skins tanned by the above process can be retanned with any other tanning material. |
