Synthesis process of sulfonic-group rhodamine compound

The invention discloses a synthesis process of a sulfonic-group rhodamine compound. The process comprises the steps: mixing saccharin and a protonic acid catalyst, performing heating for a reaction soas to obtain a compound shown in a formula (I), performing a reaction between a compound shown in a formula (II) and resorcinol through heating under the action of the protonic acid catalyst so as toobtain a compound shown in a formula (III), performing a reaction between the compound of the formula (I) and the compound in the formula (III) through heating under the action of a Lewis acid catalyst under the conditions of nitrogen protection and light shielding so as to obtain the sulfonic-group rhodamine compound shown in a formula (IV). Through the synthesis process, the use of thionyl chloride in a conventional process is avoided, the operation is simplified, the production safety is improved, the pollution to the environment is little, the reaction can be carried out under normal pressure, and the reaction has a high selectivity; and the chemical structural formulas of the compounds represented separately by the formula (I), the formula (II), the formula (III) and the formula (IV)are shown.
