Additive E with hydroxylamine
, on the other hand, has a rather positive effect on both early and final strengths of the cement.
These types of stabilization systems are usually based on a combination of powerful melt-processing stabilizers, such as phosphites, hydroxylamines
, tocopherols, or blends of these chemistries, in combination with hindered amines--which provide not only excellent UV stability, but also good long-term thermal stability.
The hydrogenolytic cleavage of the N-O bond of the hydroxylamine
10a,b has been also improved and takes place also quantitatively (+30-40% with respect to the previous method)  by performing the reaction with Pd/C 10% in ethyl acetate at room temperature for 3h (extended time).
A patent was lately published where it was shown that hydroxylamine
salts are combustion improvers .
The potential of 17 hydroxylamine
derivatives as wood preservatives was assessed on ponderosa pine sapwood blocks exposed to one of two decay fungi: Gloeophyllum trabeum or Trametes versicolor.
(48) Nitrosamine aspects in the use of hydroxylamines
to shortstop the emulsion processes of rubber latexes.
TNT degradation products include nitroaromatics, such as hydroxylamines
, azoxy-, azo-, and aminotoluenes.
