Definitions
- salts by way of example, I would mention in the first place, the chlorides and sulfates, whereas or the salts of phosphoric acid I would mention the sodium phosphate and of the. esters, for instance, the glycerinefiphosphoric acid, eventually in combination with alkali .15 or alkaline earth metals.
- Example 1 20 kilogrammespf iron sulfate chloride fto which 1 kilogramme of phosphoric acid has been To this are added, while the solution is continually stirred,]l70 liters of water wherein are contained 4.2 kilogrammes of neutral sodium carbonate. With this tanning liquor 100 kilogrammes of pelts are'tannedfiby being moved around for 6 130 8 hours in the tanning-vessel. 1 i.
- Example 2 5 kilogrammes of alum, to which are added 3 kilogrammes of common salt and 0.5 kilogrammes of glycerine. phosphoric acid are dissolved in-l00 liters of water, and in this solution 100 kilogrammes of pelts are tanned by being moved around for 6 to 8 hours in the tanning vessel. j
- the phosphoric acid, or the acids of arsenic, or the corresponding salts or esters can be added either during the tanning operation, or can be used already in the pickle, or they can be used in the stumn'g.
