What is the preparation method of 4-Dimethylaminoazobenzene-4-Sulfonic Acid, Sodium Salt?

The preparation method of the sodium salt of 4-dimethylaminoazobenzene-4-sulfonic acid, that is, methyl orange, is as follows:
Take the p-aminobenzene sulfonic acid first, place it in an appropriate amount of water, and then add a slight amount of sodium hydroxide solution, heat and stir to dissolve the p-aminobenzene sulfonic acid, and obtain the p-aminobenzene sulfonic acid sodium salt solution. This step is due to the existence of p-aminobenzene sulfonic acid in the form of internal salts, which is difficult to dissolve in water, and the solubility increases greatly after reacting with alkali to form a salt.
The above solution is cooled to room temperature, and the sodium nitrite solid is slowly added under stirring. Another appropriate amount of concentrated hydrochloric acid is slowly injected into ice water to prepare a dilute hydrochloric acid solution, which is also cooled to 0-5 ° C. Subsequently, the cooled dilute hydrochloric acid solution is slowly dropped into the mixed solution of sodium p-aminobenzenesulfonate and sodium nitrite under stirring. This process requires strict control of the temperature at 0-5 ° C. Diazotization reaction is carried out to generate a diazo salt solution.
Take N, N-dimethylaniline, add an appropriate amount of glacial acetic acid to dissolve it, and then slowly drop the solution into the above diazo salt solution under stirring. The dropwise addition process still needs to maintain a low temperature. After dripping, continue to stir the reaction for a period of time, and it can be seen that the color of the solution gradually changes to form azo
After the reaction is completed, an appropriate amount of sodium hydroxide solution is added to the reaction system to adjust the pH to alkalinity. At this time, the product is precipitated in the form of sodium salt. After heating and concentrating, the volume of the solution is reduced and the crystals are precipitated. After cooling, suction filtration is carried out to wash the crystals with a small amount of cold water to remove impurities. Finally, the crystals are placed in an oven to dry at low temperature to obtain the sodium salt of 4-dimethylaminoazobenzene-4-sulfonic acid, that is, the methyl orange product.

4-Dimethylaminoazobenzene-4-Sulfonic the price range of Acid, Sodium Salt in the market

The price range of the sodium salt of 4-dimethylaminoazobenzene-4-sulfonic acid in the market is quite complex and varies due to many factors.
The price of this substance is primarily related to its purity. If the purity is extremely high, it is almost perfect, and there is no impurity interference, its price will be high. For a high-purity product, the preparation process requires exquisite techniques, complicated processes, and consumes a lot of resources and effort, so it is natural to have a high price. If the purity is slightly lower and contains some impurities, although it can be satisfied for some ordinary uses, the price will drop slightly.
Furthermore, the scale of production is also critical. If large-scale production, due to the scale effect, the unit production cost can be reduced, and its price in the market may also be close to the people. On the contrary, if it is specially made in small batches, the production is time-consuming and laborious, and the price will be relatively high.
The supply and demand situation of the market also affects its price. If there are many people who want it, but the supply is small, and it is in a state of shortage, the price will rise. On the contrary, if the market is saturated and the supply exceeds the demand, the merchant will sell it for promotion, and the price may be lowered.
In addition, the reputation of the brand and the manufacturer also has an impact. Manufacturers with a long-standing reputation and excellent reputation may have higher prices than other factories because of their reliable quality and worry-free after-sales service.
In summary, the market price of the sodium salt of 4-dimethylaminoazobenzene-4-sulfonic acid can range from tens of yuan per kilogram to hundreds of yuan per kilogram. The specific price needs to be explored in detail according to the above factors.
