Storage condition

1. Keep the storage device sealed, stored in a cool and dry place, and ensure that the workshop has good ventilation or exhaust device.

 

stability

1. If used and stored in accordance with specifications, it will not decompose, and no known hazardous reactions will occur to avoid oxides

 

2. Good heat resistance, acid resistance, light resistance and salt resistance, stable to citric acid and tartaric acid, but poor oxidation resistance. Turn red in alkali and fade in reduction. Maximum absorption wavelength 428nm±2nm.

 

3. Yellow in concentrated sulfuric acid and yellow solution after dilution; It is a yellow solution in concentrated nitric acid. Its aqueous solution with hydrochloric acid does not change color; Adding sodium hydroxide solution deepened the red light
