Abstract
Inventia se refera la un procedeu de obtinere a sulfatului de sodiu anhidru din subprodusele solide din industria izoprenului, care consta, în principal, în dizolvarea materialului în apa, purificarea de substantele organice continute, cristalizarea sulfatului de sodiu decahidrat, transformarea acestuia în sulfat de sodiu anhidru si uscarea sulfatului de sodiu anhidru.The invention relates to a process for the production of anhydrous sodium sulphate from solid by-products of the isoprene industry consisting essentially of dissolving the material in water, purifying the organic substances contained therein, crystallising the sodium sulfate decahydrate, converting it to sodium sulfate anhydrous and drying the anhydrous sodium sulfate.
