Definitions
- tanning agents there may especially be mentioned all sulfo pounds of high molecular we linking several aromatic nuclei
- acids of condensation nic acids of comight obtained by i. e. the sulfonic products obtained from aromatic bodies (phenols, naphthalene, aniline etc.) and bridge-forming agents, such as aldehydes, sulfur, sulfur chloride.
- sulfo group may be introduced In this case the either directly or by esteriflcation, peptisation etc.
- the known synthetic tanning agents are far less sensitive to the action of electrolytes. Furthermore the properties of these new mixtures may be varied to a greater extent than those of the known synthetic tanning agents.
- the mixtures may,
- a mixture of, for instance, 50 parts of quebracho (soluble in the cold state, solid) and 50 parts of the powdered tanning a ent described above is dissolved in water so as to form a liquor of a strength of 10 B.
- cow pelts are tanned which already have been tanned through in the color pits.
- the leather obtained is of lighter color and a better. stretch and is more plump than that treated with quebracho alone.
- a tanning agent consisting of the sulfonation product from a mixture of a phenolic body are tanned in a drum.
- a tanning agent consisting of the sulfonation product from phenolic bodies and natural resins, esteriiied in the presence of catalysts, with a content of electrolyte not higher than 10 per cent., mixed with synthetic tanning agents of the group consisting of water soluble polynuclear aromatic condensation products.
- a tanning agent consisting of the sulfonation product from a mixture'of colophony and phenol and having a content of electrolyte not higher than 10 per cent., calculated upon a tanning agent of 100 per cent., mixed with synthetic tanning agents of the group consisting of water soluble polynuclear aromatic condensation prodnets.
- a tanning agent consisting of the sulfonation product from equimolecular proportions of colophony and phenol with a content of electrolyte not higher than 10 per cent., calculated upon a tanning agent of 100 per cent., mixed with synthetic tanning agents of the group consisting of water soluble polynuclear aromatic condensation products.
- a tanning agent consisting of the sulionation product from colophony and cresol and having a content of electrolyte not higher than 10 per cent., calculated upon a tanning agent of 100 per cent., mixed with synthetic tanning agents of the group consisting of water soluble polynuclear aromatic condensation products.
- a tanning agent consisting of the sulfonation product from equimolecular proportions of colophony and cresol and having a content of electrolyte not higher than 10 per cent., calculated upon a tanning agent of 100 per cent., mixed with synthetic tanning agents of the group consisting of water soluble polynuclear aromatic condensation products.
- a tanning agent consisting of the sulfonation product from colophony and xylenol and having a content of electrolyte not higher than 10 per cent., calculated upon a tanning agent of 100 per cent., mixed with synthetic tanning agents of the group consisting of water soluble polynuclear aromatic condensation products.
- a tanning agent consisting of the sulfonation product from equimolecular proportions of colophony and xylenol with a content of electrolyte not higher than 10 per cent., calculated upon a tanning agent of 100 per cent., mixed with synthetic tanning agents of the group consisting of water soluble polynuclea aromatic condensation products.
