Serial No. 117,565

(HNO4) We have found that the nitrites are inefiective in the bleaching of glue by reason of the property of nitrites to form a dark or reddish compound by the action of nitrites on proteins. nitrates do not have such an eiiect upon proteins, and the combination of hydrogen peroxide and a nitrate is peculiarly effective in bleaching glue. We have found, for example, that although potassium nitrate has no noticeable bleaching effect on glue and hydrogen peroxide has an appreciable effect, the combination of hydrogen peroxide and potassium nitrate bleaches glue to a lighter color than does hydrogen peroxide alone.
In one test of the present invention, four samples of a bone glue liquor containing 31.5 per cent. solids were placed in jars, each jar containing 400 gm. of the glue liquor or 126 gm. of the glue solids. The table shows the percentage of potassium nitrate and hydrogen peroxide added.
However,
The hydrogen peroxide was added as 30 per cent. hydrogen peroxide. was dissolved in a small amount of water and The mixture was agitated to thoroughly admix the hydrogen peroxide and potassium nitrate with the glue liquor. The samples were stored at about 100 F. for several hours and color comparisons made. The jelly and viscosity measurements were made the solution added to the liquor.
The potassium nitrate three days later.

(solids (solids 5 5 gi gf f basls) hams) grams lipoises After the bleaching action was completed, the glue liquor was evaporated and the colors of the dry glue compared. Sample No. 2 was lightest and most desirable in color. Sample No. l was next in lightness. Sample No. l had not been bleached and Sample No. 3, although slightly bleached, was not nearly as light nor as desirable in color as Samples No. 1 and No. 2.
It will be noted that the bleaching procedwre of the present invention brings about no significant changes in bloom or viscosity.
We claim:
1. The method of bleaching glue which comprises adding thereto hydrogen peroxide and a nitrate.
2. The method of bleaching glue which comprises adding thereto hydrogen peroxide and potassium nitrate.
3. The preparation of glue which comprises adding hydrogen peroxide and a nitrate to glue liquor, agitating the mixture to secure intimate admixture, permitting the combination of hydrogen peroxide and a nitrate to act upon the glue liquor, and thereafter drying the glue liquor.
4. The preparation of glue which comprises adding hydrogen peroxide and potassium nitrate to glue liquor, agitating the mixture to secure intimate admixture, permitting the combination of hydrogen peroxide and potassium nitrate to act upon the glue liquor, and thereafter drying the glue liquor.
5. In the manufacture of glue having a light color, the step of adding to the glue liquor a mixture of hydrogen peroxide and a nitrate.
6. In the manufacture of glue having a light WALTER M. URBAIN. LLOYD B. JENSEN.
