Interaction and solid-state reaction between manganese chloride tetrahydrate and Y zeolites (NaY or LaNaY)

Abstract

Mixtures of Y zeolites (NaY or LaNaNH₄Y) and manganese chloride tetrahydrate are treated in air at atmospheric pressure. Depending on the treatment temperature, T_t, three successive processes can occur: maximum halide insertion into the supercages at low temperature (503 K); maximum cation exchange at 683 K and solid–solid reactions with the appearance of new crystalline phases at ca. 1073 K.
