Abstract
POSTUPAK ZA SMANJENJE SITNIH ALUMINIJUMOKSID TRIHIDRATNIH KRISTALA, koji se dobijaju za vreme kristalizacije aluminijumoksid trihidrata iz tople, kaustične sirove tečnosti iz Bajerovog procesa, pri čemu se povećava prinos aluminijuma, naznačen time, što se vrši dodavanje u sirovu tečnost, posle uklanjanja crvenog mulja i neposredno pre kristalizacije aluminijumoksid trihidrata dve medjusobno rastvorene komponente, pri čemu je prva komponenta površinski aktivno sredstvo, kao što su masne kiseline sa najmanje zasićenim ili nezasićenim c4 alkil nizom sa ili bez jedne više karboksilne, estarske anhidrovane ili sulfatne funkcionalne grupe vezane direktno ili preko sukcinskog alkila, koje disperguje ulje kao drugu komponentu, kao što je ulje odabrano od parafinskog, naftenskog, smeše parafinskog i aromatičnog i ostatka iz destilacije C10 alkila, u sirovoj tečnosti, pri čemu ulje u kome je površinski aktivno sredstvo rastvoreno ima tačku ključanja iznad temperature koja vlada za vreme kristalizacije aluminijum hidrata. Prijava sadrži još 1 zahtev.
