Book excerpt: Excerpt from Action of Sodium Sulphate in Synthetic Tanning Materials It therefore follows that if a hide is treated with a solution contain ing both sodium sulphate and a synthetic tanning material (which is usually an active acid) both the sulphuric acid and the tanning material will combine with the hide to a certain extent. In other words, the neutralization of the excess sulphuric acid ln syntans, by means of sodium hydroxide or any other reagent 'which yields a soluble sulphate, does not entirely prevent the sulphuric acid from reacting with the hide during the tanning process. The extent to which the sulphuric acid and the synthetic tanning agent will combine with the hide under these conditions is not yet definitely known, but it is probable that an equilibrium will ultimately be reached, depending partly on the nature of the syntan and partly on the concentrations of the reagents in the tanning solution. But whatever the amount of the sulphuric acid which will be combined ln the leather, the results obtained in the present study indicate that this can not be com pletely removed by any amount of washing with water at ordinary temperatures. It is possible and even probable that this combined sulphuric acid which remains in the leather after thorough washing will have no injurious effect on it, but this still remains to be definitely ascertained. In any case, thorough washing of the leather after using a syntan which contains any considerable amount of sodium sulphate or other soluble sulphate is always necessary in order to prevent injury from the free sulphuric acid which would result from the inter action of the sulphate with any excess of uncombined sulphonic acid.

Book excerpt: In 1901 the National Bureau of Standards (NBS) was founded to provide standard weights and measures and to be the national physical laboratory for the United States of America. The NBS conducted a lot of research in the fields of science and technology which were reported as "Technological Papers." In 1988 the NBS became what we know now; the National Institute of Standards and Technology (NIST). This is one of those documents written by employees of the NBS.
