Abstract:

A comprehensive applied chemistry experiment is introduced in this paper, including the synthesis, characterization, and performance of ammonium polyphosphate (APP). This experiment consists of the preparation of APP by low-temperature solvent method, the characterization of APP through Fourier-transform infrared spectroscopy and X-ray diffraction analysis, and the examination of solubility, flame retardancy as well as oxygen index. This experiment can improve students' ability to broaden the basic chemical knowledge and cultivate the critical thinking, which would greatly assist the training of students' solid and comprehensive skills, thus, improving the teaching quality of the applied chemistry major.

Key words: Ammonium polyphosphate (APP), Fire retardant, Oxygen index, Comprehensive applied chemistry experiment
