化学的性質

化学的特性Potassium persulfate is a colorless or white, odorless crystalline material.

Excerpt from ERG Guide 140 [Oxidizers]:

CAUTION: Ammonium nitrate products may explode if involved in fire or contaminated with hydrocarbons (fuels), organic matter, other contaminants or when hot molten and contained. Treat as an explosive (GUIDE 112).

Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with combustible substances.

Health Hazards · 2 件

Excerpt from ERG Guide 140 [Oxidizers]:

· Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death.

Hazards Summary · 1 件

Frequent skin rashes are reported in workers exposed to persulfates (S2O8). Rats inhaling 4-20 mg/m3 of ammonium persulfate 23.5 hours/day for 7 days show signs of lung inflammation and loss of body weight. The TLV is proposed to reduce irritation of skin, throat, and respiratory tract. [ACGIH] May cause skin sensitization; [CHEMINFO] May cause respiratory sensitization; [eChemPortal: NICNAS] A skin, eye, and respiratory tract irritant; May cause skin sensitization, dermatitis, and asthma after prolonged contact; May cause general allergic reaction, like urticaria or shock. [ICSC] An irritant; May cause skin and respiratory sensitization after prolonged contact; [MSDSonline] It may induce either Type I reactions (urticaria, anaphylaxis, and asthma) or Type IV reactions (allergic contact dermatitis).

Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.

First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again.

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 .

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· Keep combustibles (wood, paper, oil, etc.) away from spilled material.

First Aid · 2 件

Excerpt from ERG Guide 140 [Oxidizers]:

General First Aid:

Safe StorageCool. Dry. Well closed. Separated from combustible substances, reducing agents and strong bases.
Exposure Control and Personal Protection· Wear positive pressure self-contained breathing apparatus (SCBA).
Storage ConditionsKeep containers closed and store in cool dark places.
Cleanup Methods · 1 件

Cover with reducing agents such as hypo, bisulfites or ferrous salts. Bisulfites or ferrous salts need additional promoter of some 3M sulfuric acid to accelerate reaction. Transfer the slurry (or sludge) into a large container of water and neutralize with soda ash. Drain into a sewer with abundant water.

Nonfire Spill ResponseExcerpt from ERG Guide 140 [Oxidizers]:
Disposal MethodsUse vast volume of concentrated solution of reducing agent (bisulfites or ferrous salts with 3M sulfuric acid or hypo). Neutralize with soda ash or dilute hydrogen chloride. Drain into a sewer with abundant water.
Spillage Disposal · 1 件

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Do NOT absorb in saw-dust or other combustible absorbents. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Cautiously neutralize remainder. Wash away remainder with plenty of water.

The CIR Expert Panel concluded that Ammonium, Potassium, and Sodium Persulfate are safe as used as oxidizing agents in hair colorants and hair lighteners designed for brief discontinuous use followed by thorough rinsing from the hair and skin. The Panel also concluded that the available data are insufficient for determining the safety of these persulfates in leave-on products and dentifrices.

Potassium persulfate is a dangerous fire risk in contact with organic materials. It is a strong oxidizing agent and an irritant, with a four-digit UN identification number of 1492. The primary uses are in bleaching, as an oxidizing agent, as an antiseptic, as a polymerization promoter, and in the manufacture of pharmaceuticals.

使用Potassium persulfateis a powerful oxidant, commonly used to initiate polymerizations. Potassium Persulphate used for bleaching and textile desizing, as an oxidizing agent and antiseptic, in purification of ammonium sulfate, and in the manufacture of soap and pharmaceuticals. It is also used as al laboratory oxidant and photography chemical. It is a food additive.

一般的な説明A white crystalline solid. Specific gravity 2.477. Decomposes below 100°C.

調製方法 · 2 件

製造方法Potassium persulfate can be prepared by electrolysis of a mixture of potassium sulfate and potassium hydrogen sulfate at a high current density:2KHSO4→K2S2O8+ H2Also, the compound can be prepared by adding potassium hydrogen sulfate,KHSOto an electrolyzed solution of ammonium hydrogen sulfate, NH4HSO4.

純化方法Crystallise the persulfate twice from distilled water (10mL/g) and dry it at 50o in a vacuum desiccator. Its solubility in H2O is 1.6% at 0o, 4.5% at 20o, and 7.2% at 30o. An aqueous solution decomposes on long standing with evolution of O2 and formation of KHSO4. It is a powerful oxidising agent. Store it at ~10o.
