Ammonium persulfate：
Molecular formula : (NH4)2S2O8
CAS NO.: 7727-54-0
EINECS NO.: 231-786-5
Dangerous goods number：51504
Application：
Verification and determination of manganese, used as oxidant, bleach. Photographic reducing agent and retarder. Battery depolarizer. Used in the preparation of soluble starch.
It is used as an initiator for the emulsion polymerization of vinyl monomers such as vinyl acetate and acrylic esters. The price is cheap and the resulting emulsion has good water resistance. It is also used as a curing agent for urea-formaldehyde resin, with a faster curing speed. It is also used as a co-oxidant for starch adhesives. It reacts with proteins in starch components to improve adhesion. The reference dosage is 0.2% to 0.4% of starch. Also used as a metal copper surface treatment agent.
The chemical industry is used as a raw material for manufacturing persulfate and hydrogen peroxide, a polymerization aid for the polymerization of organic polymers, and an initiator for the polymerization of vinyl chloride monomers. Grease and soap industry are used as bleaching agents. It is also used in corrosive agent for metal plate erosion and cutting and oil production in petroleum industry. Food grade is used as wheat modifier and beer yeast mold inhibitor.
Package：
plastic bag or two-layer kraft paper bag with full or middle opening steel drum; plastic bag or two-layer kraft paper bag with ordinary wooden box; screw-top glass bottle, iron-capped glass bottle, plastic bottle or metal barrel (can ) Outside ordinary wooden box.
Storage and transportation：
Attentions for transportation: When transporting by rail, it should be strictly assembled in accordance with the dangerous goods matching table in the "Dangerous Goods Transportation Rules" of the Ministry of Railways. It is shipped separately during transportation, and the container must not leak, collapse, fall or damage during transportation. Transportation vehicles should be equipped with corresponding types and quantities of fire-fighting equipment during transportation. Mixed transportation with acids, flammables, organics, reducing agents, spontaneously combustibles, flammables when wet, etc. is strictly prohibited. During transportation, the speed should not be too fast, and no overtaking is allowed. Transport vehicles should be thoroughly cleaned and washed before and after loading and unloading. It is strictly prohibited to mix impurities such as organic matter and flammable substances.
Precautions for storage: Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat. The packaging must be sealed to prevent moisture. It should be stored separately from reducing agent, active metal powder, etc., and avoid mixed storage. The storage area should be equipped with suitable materials to contain the leakage.
Incompatible materials: strong reducing agent, active metal powder, water, sulfur, phosphorus.
Conditions to avoid contact: Moist air.
