microporous crystalline material (ITQ-19) with laminar characteristics, its preparation process and its use as catalyst in catalytic conversion processes of organic compounds. A new microporous crystalline material ITQ-19, useful in catalytic conversion processes of organic compounds, such as dewaxing and isodewaxing of paraffins and toluene disproportionation, which diffractogram characteristic X-rays and a high adsorption capacity and has the empirical formula x (M1 / n XO 2): y YO2: (1-y) SiO2, where x has a value less than 0.2; and it has a value less than 0.1; M is at least one inorganic cation of charge + n; X is at least one chemical element with oxidation state +3, preferably selected from Al, Ga, B, Cr, Fe; Y is at least one chemical element with oxidation state +4, preferably selected from Ge, Ti, Sn, V. This material is obtainable by a preparation process involves the use of one or more organic additives in a reaction mixture which is crystallized by heating.
