| Hazard Information | Back Directory | [Chemical Properties]
Cupric oxalate is a bluish-white, odorless powder. | [Uses]
As catalyst for organic reactions; as stabilizer for acetylated polyformaldehyde; in anticaries compositions; in seed treatments to repel birds and rodents. | [General Description]
Odorless bluish-white solid. Denser than water and insoluble in water. Hence sinks in water. Used as a catalysts for organic reactions. | [Reactivity Profile]
CUPRIC OXALATE(814-91-5) dissolves in aqueous ammonia and reacts as an acid to neutralize other bases as well. Can serve as a reducing agent in reactions that generate carbon dioxide. | [Air & Water Reactions]
Insoluble in water. | [Hazard]
Toxic by ingestion; tissue irritant. | [Health Hazard]
Inhalation causes irritation of nose and throat. Ingestion of very large amounts may produce symptoms of oxalate poisoning; watch for edema of the glottis and delayed constriction of esophagus. Contact with eyes causes irritation. | [Potential Exposure]
Used as a catalyst for organic reactions and in seed treatment as a repellent for birds and rodents. | [Fire Hazard]
Special Hazards of Combustion Products: Toxic carbon monoxide gas may form in fire. | [First aid]
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy. | [Shipping]
UN2775, Copper based pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials. | [Incompatibilities]
Explosive materials are formed on contact with acetylene gas, ammonia, caustic solutions; sodium hypobromite, nitromethane. Slight heating can cause a weak explosion. Cupric oxalate dissolves in aqueous ammonia and reacts as an acid to neutralize other bases as well. Can serve as a reducing agent in reactions that generate carbon dioxide. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. | [Description]
Cupric oxalate is a bluish-white, odorless powder. Molecular weight=153.58. Hazard Identification(based on NFPA-704 M Rating System): Health 1,Flammability 0, Reactivity 1. Insoluble in water | [Preparation]
Copper(II) oxalate can be prepared by reaction of sodium oxalate with copper(II) salt solutions. Copper(II) oxalate is used as a catalyst in organic reactions and as a stabilizer for acetylated polyformaldehyde. | [storage]
Color Code—Green: General storage may be used.Prior to working with cupric oxalate you should be trainedon its proper handling and storage. Store in tightly closedcontainers in a cool, well-ventilated area away from acetylene gas, ammonia, caustic solutions, and nitromethane. |
