ZEOLITE 4A WITH NEW MORPHOLOGICAL PROPERTIES, ITS SYNTHESIS AND USE

摘要

The present invention discloses zeolite 4A with molar oxide composition of 1.017Na2O ° Al2O3 ° 1.973SiO2 ° 4.725H2O that has external specific surface area of 2.37-4.43 m2/g according to Brunauer-Emmett-Teller (BET) isotherm; and - external surface roughness as indicated by the ratio of RSSA/GSSA within the range of 2.58-2.81. Particles size of zeolite 4A are ranging from 0.4 µm to 5 µm, wherein 50% of all particles size are smaller than 1.45 µm, and 90% of all particles size are smaller than 2.35 µm. Invention can be used as detergent builder, ion-exchange agent, sorbent, and carrier of organic molecules.
