Chemical: Sulfuric acid, cobalt(2+) salt (1:1), heptahydrate
Regulation (EC) No 1831/2003 (amended)
Sulfuric acid, cobalt(2+) salt (1:1), heptahydrate is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Sulfuric acid, cobalt(2+) salt (1:1), heptahydrate are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)
Literature sources indicate that this chemical is nonflammable. (NTP, 1992)
Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
SYMPTOMS: Symptoms of exposure to this compound via inhalation include coughing and shortness of breath. Inhalation may cause irritation of the respiratory tract and mucous membranes. It may also cause permanent disability. Ingestion of this compound may result in nausea, vomiting, abdominal pain, vasodilatation, mild hypotension, rash and ringing in the ears. It can cause irritation, redness and pain on skin or eye contact. Skin contact may also result in allergic reactions. Other symptoms include headache and nervous system disturbances. Repeated ingestion may produce a goiter and reduce thyroid activity. Prolonged or repeated skin contact may cause dermatitis. Lung disease sometimes occurs on inhalation of this type of compound.
解説硫酸コバルトとは、コバルトの硫酸塩の無機化合物です。 硫酸コバルトには、硫酸コバルト (II) と硫酸コバルト (III) の2種類が存在します。硫酸コバルト (II) には、無水物、一水和物、七水和物が知られています。 硫酸コバルト (II) の七水和物は、濃紅色の柱状結晶です。別名、赤バン (英: bieberite) とも呼ばれています。日本で赤バンは、奈良県の堂ヶ谷鉱山や山梨県の鳳来鉱山などで確認されています。
用途メッキ添加剤、触媒
用途磁性体用、金属石けん?顔料原料、塗料?インキ乾燥剤、防錆材原料、飼料添加物、メッキ薬、触媒
使用Usual source of water-soluble cobalt since it is the most economical and it shows less tendency to deliquesc or dehydrate than the chloride or nitrate. Used in storage batteries; in Co-electroplating baths; as drier for lithographic inks, varnishes; in ceramics, enamels, glazes to prevent discoloring; in Co pigments for decorating porcelain.
一般的な説明Pink to red monoclinic prismatic crystals or red granular solid. Odorless. Becomes anhydrous at 788°F.
使用用途硫酸コバルト (II) は、コバルトめっきや磁性材料、陶磁器の釉薬、コバルト塩の製造などに用いることが可能です。また、防錆材原料や各種や、ぺイント・インキの乾燥剤、や陶磁器の彩色用顔料、触媒、金属せっけん、不可視インク原料など、幅広い用途が挙げられます。 硫酸コバルト (II) は、医薬品分野では、貧血用薬にミネラル成分として配合されています。さらに、農業分野においても、同様の目的で、飼料添加物として使用可能です。 それに対して硫酸コバルト (III) は、強い酸化剤として使用されています。
純化方法Crystallise it three times from conductivity water (1.3mL/g) between 100o and 0o depending on which hydrate is required. The heptahydrate crystallises below 44o and is efflorescent with m 97o . Between 44o and 70o the monoclinic hexahydrate CoSO4.6H2O m 41.5o is formed, and above 70o the monohydrate CoSO4.H2O m 71o is obtained. The pale reddish or lavender-coloured anhydrous salt is obtained by heating the hydrate above 250o, boiling with conc H2SO4 or heating with (NH4)2SO4).

10026-24-1DTXSID7020340CHEBI:91244化学的特性Cobalt sulphate appears as pink or red crystals. It is stable, non-flammable, and hygroscopic and undergoes dehydration at 41°C and 71°C.
Acidic salts, such as COBALT SULFATE HEPTAHYDRATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
In case of fire in the surroundings, use appropriate extinguishing media.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .
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.
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.
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.
Cough. Laboured breathing. Shortness of breath. Sore throat.
Redness. Pain.
Redness. Pain.
Abdominal pain. Nausea. Vomiting.
