Disclosed is a synthesis process of a crystalline material with the CHA structure, which comprises the following steps: i) Preparation of a mixture that comprises one source of water, one source of a tetravalent element Y, one source of an alkaline or alkaline earth cation (A), one source of a trivalent element X, and one organic molecule (OSDA1) with the structure [R 1 R 2 R 3 R 4 N + ]Q − , being the molar composition: n X 2 O 3 :YO 2 :a A:m OSDA1:z H 2 O, ii) crystallisation of the mixture obtained in i) in a reactor, iii) recovery of the crystalline material obtained in ii). |
