Chemical Properties
violet powder
Uses
2,5-Diaminobenzenesulfonic acid was used in preparation of a polymeric dye, required for laccase-mediated dyeing of cotton.
General Description
2,5-Diaminobenzenesulfonic acid is a dye precursor. Electrochemical copolymerization of 2,5-diaminobenzensulfonic acid and aniline by cyclic voltammetry on IrO2 coated titanium electrodes was reported.
Flammability and Explosibility
Non flammable
Synthesis
Weigh 39g of iron powder added to 1000mL four flask, add water 300mL stirring, add 6g of ammonium chloride and 4mL concentrated hydrochloric acid, warming to 95 ??, slowly add nitro to add speed to regulate the temperature to maintain above 90 ??, add too fast easy to rush material danger, add continue to hold for a period of time, when taking a drop of the reaction liquid drop to the disappearance of the yellow ooze circle on the filter paper that is the end point of the reaction, add sodium hydroxide solution to adjust pH = 10, filtration, filtration is 2,5-diaminobenzenesulfonic acid. Add sodium hydroxide solution, adjust pH=10, filter, add hydrochloric acid to the filtrate acid precipitation, filtration that is 2,5-diaminobenzenesulfonic acid.
