Abstract:
Solid wastes from organic Adhesive production are identified as toxicant hazardous wastes in China's National Catalogue of Hazardous Wastes. The aim of this study is analyzing the thermal behavior of Adhesive residue. Its pyrolysis and combustion characteristics were investigated using thermogravimetric analysis (TGA). Experiments were carried out in the temperature range of 50-950 degrees C in both nitrogen and air. The results indicate that combustion under these experimental conditions largely occurs between 210 and 410 degrees C, whereas pyrolysis proceeds between 260 and 430 degrees C. Almost all weight lost takes place before 430 degrees C during both pyrolysis and combustion of the residue. Fourier transform infrared spectroscopy (FTIR) was used to characterize the emission characteristics during pyrolysis. When the sample is heated in an inert atmosphere, the evolution of volatiles starts around 260 degrees C, and reaches a peak rate at 394 degrees C. Most organic products evolve in a narrow temperature range during pyrolysis. The evolving gaseous products were identified as Butyraldehyde, Ether, Acetonitrile and CO2, accompanied with some CO.

Surface Tension, Capillary Action, and Viscosity
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

Thermal Sigmatropic Reactions: Overview
Sigmatropic shifts are classified based on an order term [i, j ], where i and j indicate the number of atoms across which each end of the σ bond migrates. Below are examples of a [3,3] sigmatropic shift in 1,5-hexadiene, referred to as...
