CRAQUEAMENTO TÉRMICO DA GLICERINA: UMA PROPOSTA DE EXPERIMENTO PARA QUÍMICA ORGÂNICA

In this work, an undergraduate organic chemistry experiment based on thermal cracking of glycerin is proposed. The reagent is obtained as a by-product from the practice of biodiesel synthesis, and allows reduction of waste produced in the lab. The main product obtained from thermal cracking was char...
