Thermal degradation of agar: Mechanism and toxicity of products.

Food Chemistry, 2018
The mechanism of the thermal degradation and the toxicity of the thermal degradation products of agar were studied using TG/DTA, Fourier-transform infrared spectroscopy and pyrolysis gas chromatography/mass spectrometry.

Thermal degradation of actinomycins to dioxopiperazines

Journal of the Chemical Society, Perkin Transactions 1, 1975
The dioxopiperazines resulting from thermal degradation of several actinomycins were identified by g.l.c. comparison with synthetic compounds, providing a convenient approach to amino-acid sequence determination. In a comparison of relative yields of various dioxopiperazines, different degradative pathways were apparent at different temperatures.

Thermal degradation of deproteinized natural rubber

Polymer degradation and stability, 2018
Thermal degradation of deproteinized natural rubber (DPNR) was investigated by heating at 70 °C and 150 °C for 24 h, which was compared with thermal oxidative degradation of natural rubber (NR).

Thermal degradation of UHMWPE

Journal of Thermal Analysis, 1997
The thermal behaviour of ultra-high molecular weight polyethylene (UHMWPE) of different molecular weights was examined by thermal analysis methods. The melting temperatureTm and the heat of melting δH were measured by the DSC method. The thermooxidative degradation process was investigated by using a MOM Q-1500 D derivatograph at various heating rates ...
