More Information
Summary:The present invention relates to a new basic aluminum magnesium carbonate of the formula (I): Al2Mg4(OH)12CO3.3H2O and rhombohedral crystallization, whose reticular parameters are a=b=3,046 ANGSTROM ; c=22.79 ANGSTROM ; alpha = beta =90 DEG ; gamma =120 DEG and cell volume = 183 A , whose X-ray diffraction spectrum shows the following d( ANGSTROM ) values: 7.597; 3.798; 2.6202; 2.5698; 2.5322; 2.2830; 1.93545; 1.72447; 1.62930; 1.52289; 1.49318; 1.46002; 1.41351; 1.38528 and 1.31011; whose infrared spectrum shows characteristic bands at 1361 and 449 cm<-1> (Figure 1) and whose differential scanning calorimetry (DSC) is illustrated in Figure 2. This compound is used in therapeutics as an antacid and gastroprotector.
