| Descripción: | One of the significant boron compounds which are common substance in nature is ulexite. Ulexite is a sodium calcium boron hydrate, its chemical formula is Na2O2CaO5B2O316H2O , and it is thick with in Turkey. Lots of products are derived from boron minerals. One of them is boric acid. CaCl2 is used in many fields and this compound can be obtained by different processes. The aim of this study is producing CaCl2 by forming mathematical model for CaCl2 composing in the wake of the interaction of ulexite with hydrochloric acid solution. In the study, full factorial desing method has been used. Some of the parameters used in the process have been pegged, and the others have been regarded as variables. The pegged parameters are particle size, reaction time and stirring speed. Hydrochloric acid concentration, temperature and solid to liquid ratio have been regarded as variable factors in formation of mathematical model. The mathematical model of three-parameter full factorial desing mehtod and the mathematical model of the process have initially been assessed in dimensionless coordinate system, then the available values in the model have been computed by Student criteria, the validity of the formed model has been controlled by Fisher criteria. Henceforwards, the current model of the process has been formed in real coordinate system. Key words: ulexite, calcium chloride, full factorial desing, mathematical model. |
