Abstract

processo de obtenção de glicerina purificada - a presente invenção refere-se a um processo para purificação de glicerina loura, oriunda da produção do biodiesel,, composta por uma etapa de formação de uma fase líquida contendo um intermediário heterocíclico, classificado como cetal, facilitando a perfeita precipitação dos sais orgânicos e inorgãnicos, normalmente de dificil remoção. numa etapa posterior, a fase líquida é hidrolisada concomitantemente com a evaporação da acetona permitindo que o material de partida seja recuperado em rendimento químico quantitativo e alto grau de pureza.Purified Glycerin Process - The present invention relates to a process for purifying blond glycerin from biodiesel production, comprising a step of forming a liquid phase containing a heterocyclic intermediate, classified as ketal, facilitating the Perfect precipitation of organic and inorganic salts, usually difficult to remove. at a later stage, the liquid phase is hydrolyzed concurrently with evaporation of acetone allowing the starting material to be recovered in quantitative chemical yield and high purity.
