With increasing ammonolysis temperature, the lattice parameters b, c, and [beta] gradually increase resulting in an expanded unit-cell volume.
It increased with increasing ammonolysis temperature indicating an enhanced nitridation at elevated temperatures excluding the powder synthesized at 800[degrees]C.
Thermal ammonolysis causes a redshift of the absorption edge into the visible light region.
The oxygen evolution rate as a function of the ammonolysis temperature is shown in Figure 6 and Table 2.
The data in Table 2 exhibit general trends: with increasing ammonolysis temperature crystallite and particle sizes increase, while the surface area of the [beta]-TaON powders decreases due to sintering processes.
This is not the case in the DuPont ammonolysis process, which targets the formation of nitriles, and subsequently, HMD.
In this section, we review some of the modeling efforts for the depolymerization of nylon 6 to caprolactam  as well as the ammonolysis of nylon 6,6 and nylon 6 mixtures .
A kinetic model of the depolymerization of nylon 6 and nylon 6,6 mixtures via DuPont's ammonolysis route was more recently proposed by Kalfas (29).
The nylon is then sent to a pilot ammonolysis plant in Kingston, Ontario, for depolymerization.
