Abstract

"SOLUçõES ESTáVEIS DE TRIS (DERIVADOS DE ORGANOFóSFORO) DE TERRAS RARAS EM UM SOLVENTE DE HIDROCARBONETO". As soluções estáveis de tris (organofosfato) de terras raras compreendem um tris (organofosfato) de terras raras e um solvente de hidrocarboneto. De cerca de 2% a cerca de 10% de elemento de terras raras, preferencialmente, de cerca de 3% a cerca de 8% estão presentes nas soluções. As soluções de tris (organofosfato) de terras raras são estáveis quanto à precipitação do tris (organofosfato) de terras raras, por pelo menos cerca de quinze (15) dias, preferencialmente, por pelo menos cerca de vinte (20) dias e, mais preferencialmente, por pelo menos cerca de trinta (30) dias. Um processo para a preparação dessas soluções é descrito aqui. Um aditivo de estabilização, ácido, glicol ou misturas dos mesmos é utilizado para inibir a precipitação. As relações molares de ácido livre, glicol e/o água para elemento de terras raras são controladas, para se inibir a precipitação.
