Microporous crystalline material, preparation process, detergent composition is to contain this microporous crystalline material and application thereof

摘要

In the present invention, a kind of microporous crystalline zeolite A-LSX material names are disclosed to include in its anhydrous form, are formed corresponding to the oxide molar of general formula I, in the accompanying drawings: M M, it is identical or different, represents the chemical valence n of cation alkali or alkaline earth metal; 2. are indicated with z1 and 2.Number between 6 extremely includes. The microporous crystalline material, which can prepare to contain including a) preparing two aqueous solution, is respectively as follows: ali20i3 and Mi2/nO or Ali20i3 mixture M+Mi2/nO ' i2/nO; With mixture M+Mi2/nO ' i2/nO; Si0i2 and Mi2/nO or Si0i2 mixture M+Mi2/nO ' i2/nO; Wherein the amount of reactant, which reaches, meets following molar ratio: Si0i2/Ali20i3 is from 2.30 to 2.60, extremely include; (M2/nO+M ' 2/nO)/SiO2 is from 2.40 to 1.20, extremely include; (Mi2/nO+M ' i2/nO/Si0i2) is from 2.40 to 1.20 extremely include; Mi2/nO/ (Mi2/nO+M ' i2/nO) is from 0.91 to 1.00, extremely include; Hi2O/ (Mi2/nO+M ' i2/nO) extremely includes from 20 to 40; Step b) divides the mixture of two preparations and 30 points into time degC 1 of the contact degC temperature between 20 and 70 in stage a); Step c) the agings mixture is in stage b) in obtain temperature 60 and 70 between degC degC between 30 minutes time and 15 hours; Times 10 of the step d) between the degC degC between the temperature 90 and 100 of the stage c) crystalline mixtures obtained divides and 120 points. The microporous crystalline material being prepared can be used for laundering of textile fabrics and for dish-washing machine.
