Each notification may be associated with multiple companies.

Fire Fighting：

Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)

Nonfire Spill Response：

SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces 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 under ambient temperatures. (NTP, 1992)

Personal Protective Equipment：

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

Drug Information

MeSH：

Chemicals and substances that impart color including soluble dyes and insoluble pigments. They are used in INKS; PAINTS; and as INDICATORS AND REAGENTS. (See all compounds classified as Coloring Agents.)

Health Hazards：

ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits very toxic fumes of sodium oxide, nitrogen oxides and sulfur oxides. (NTP, 1992)

First Aid：

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)

Reactive Blue 19 Use and Manufacturing

Methods of Manufacturing

Taking bromamine acid and m-(2-hydroxyethylsulfone) aniline as raw materials, firstly, m-(2-hydroxyethyl sulfone) aniline is condensed with bromamine acid, and then esterified in concentrated sulfuric acid. After salting out, Filter and dry to get the finished product. . The new preparation method is to synthesize meta-ester [m-(2-sulfate ethylsulfone) aniline], and then condense with bromamine acid. . The reaction process conditions are: catalyst: CuSO4/SnCl2 composite catalyst, added in 3 times during the reaction. Catalyst: Bromo acid (substance ratio) = 0.25-0.3 NaHCO3: Bromo acid (substance ratio) = 7.0-8.0 Meta-ester: Bromo acid (substance ratio) = 1.5-1.6 Reaction temperature: 30-40℃ reaction time: 1-1.5h pH value of medium: 7.6-7.8 (continuously add NaHCO3 solution to adjust during the reaction).
