Nonfire Spill Response：

SMALL SPILLS AND LEAKAGE: If a spill of this chemical occurs, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with acetone and transfer the dampened material to a suitable container. Use absorbent paper dampened with acetone to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned. STORAGE PRECAUTIONS: You should store this material in a refrigerator. (NTP, 1992)

Drug Information

First Aid：

EYES: Check for contact lenses and remove them at once if present. You should then immediately flush eyes with water for 15 minutes. Do not use oil or ointment in eyes. Arrange immediate transportation to a medical facility. SKIN: You should remove all contaminated clothing and flood skin with water. Wash all affected skin areas thoroughly with soap and water. If symptoms persist or develop, seek medical attention. INHALATION: If any of your personnel should inhale this substance you should remove them immediately to open air. If symptoms develop, seek medical attention. INGESTION: If the exposed person is convulsing or unconscious, you should not attempt first aid. Transport immediately to a hospital emergency room or poison control center. If the victim is conscious, administer large volumes of liquid then immediately INDUCE VOMITING. Transport at once to a medical facility. (NTP, 1992)

Vat Orange 7 Use and Manufacturing

Methods of Manufacturing

Take 1, 4, 5, 8-naphthalenetetracarboxylic acid and o-phenylenediamine as raw materials, condense in acetic acid medium, and obtain the product after separation and purification. The mixture of cis and trans isomers is reduced scarlet GG (CIVat Red 14), after separation, the cis isomer is reduced claret 2R (CIVat Red 15); trans isomer It is reduced orange GR (CIVat Orange 7). Add 1 part of naphthalenetetracarboxylic acid, 0.9 part of o-phenylenediamine and 7.5 parts of glacial acetic acid to the reaction kettle, heat to 115°C, reflux for 5 hours, and then distill the acetic acid. Then add hot water, boil at 90°C for 30 minutes, filter, and wash the filter cake with hot water until it is neutral. Dried below 100°C to obtain reduced scarlet GG. The prepared reduced scarlet GG is heated in an ethanol solution of sodium hydroxide for two separations, and reduced brilliant orange GR and reduced claret 2R are obtained respectively.
