Some common heterocyclic compound, 7681-82-5, name is Sodium iodide, molecular formula is INa, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Quality Control of Sodium iodide
General procedure: All reagents were ACS-reagent grade. Distilled water was used for the preparation of solutions. The procedure for the preparation of CaApOH is as follows: samples of 1.2g Ca(NO3)2ยท4H2O, 0.5g Na3PO4, and 0.04g NaOH were placed in the bottom of a 125mL Erlenmeyer flask equipped with a standard taper joint bearing a condenser with a thermometer inserted in the condenser and held slightly above the bottom of the flask (but in the solution) by a thin slice of suction tubing at the top of the condenser. The flask was placed on a heating/stir plate and 50mL of distilled water was added. The solution was stirred magnetically and heated to 80C for approximately 3h. The pH was measured, but not adjusted, at the beginning and at the end of the 3h of digestion using Hydrion pH 1.0-12.0 paper. [In order to determine the effect of pH, the pH was adjusted with 3 M NaOH for some samples at the beginning and during digestion.] Stirring was then discontinued and the solution was allowed to cool and settle overnight. The precipitate was suction filtered in a medium porosity glass filter crucible and washed 5 times with a total of about 150mL of distilled water. The precipitate was dried in a vacuum drying oven at 110 C for at least 4h and then ground with a mortar and pestle and stored in a closed, parafilmed vial.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 7681-82-5, its application will become more common.
