Process for the preparation of lamellair lithium aluminate and its use as PVC stabilizer

摘要

Production of lamellar lithium aluminate (I) comprises reacting an aqueous solution containing at least one lithium salt and anions with a sodium aluminate solution and then separating the product at a pH of at least 6. Production of lamellar lithium aluminate of formula (I) comprises reacting an aqueous solution containing at least one lithium salt and An- ions with a sodium aluminate solution and then separating the product at a pH of at least 6: x = a number greater than 0 and less than 1; A = an n-valent anion; w = a number greater than 0 and no more than 1.
