64-02-8 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 64-02-8 differently. You can refer to the following data:
1. White powder. Freely soluble in water.
2. Tetrasodium EDTA is a white crystalline solid.
Uses
General-purpose chelating agent.
Potential Exposure
Used therapeutically in treating arteriosclerosis. Used as a metal cleaner; in detergents, liquid soaps; shampoos; metal chelating agent; in textiles industry to improve dyeing, scouring, and detergent operations; antioxidant.
Shipping
UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.
Incompatibilities
Compounds of the carboxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water and a salt that may be harmful. Incompatible with arsenic compounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat, toxic and possibly flammable gases), thiosulfates and dithionites (releasing hydrogen sulfate and oxides of sulfur). 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. Can solubilize metals
Waste Disposal
It is inappropriate and possibly dangerous to the environment to dispose of expired or waste drugs and pharmaceuticals by flushing them down the toilet or discarding them to the trash. Household quantities of expired or waste pharmaceuticals may be mixed with wet cat litter or coffee grounds, double-bagged in plastic, discard in trash. Larger quantities shall carefully take into consideration applicable DEA, EPA, and FDA regulations. If possible return the pharmaceutical to the manufacturer for proper disposal being careful to properly lab el and securely package the material. Alternatively, the waste pharmaceutical shall be labeled, securely packaged and transported by a state licensed medical waste contractor to dispose by burial in a licensed hazardous or toxic waste landfill or incinerator
Check Digit Verification of cas no
The CAS Registry Mumber 64-02-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 6 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 64-02:
(4*6)+(3*4)+(2*0)+(1*2)=38
38 % 10 = 8
So 64-02-8 is a valid CAS Registry Number.

Paragraph 0014-0019, (2018/02/04)
The invention discloses a method for preparing ethylene diamine tetraacetic acid disodium by means of a membrane chemical reactor. The method comprises the steps of 1, material feeding, wherein a certain amount of deionized water is put into the membrane chemical reactor, and then liquid sodium hydroxide and ethylene diamine tetraacetic acid are put into the membrane chemical reactor according to the mass ratio of 2:4 at 95 DEG C by eight batches till the pH value of reaction solution is 5; 2, heat insulation, after materials are fed, heat insulation is conducted on the reaction solution at 90 DEG C for 45 min, and the pH value of reaction solution is controlled to be 5. The preparing process is simple, parallel reaction selectivity and safety are high, three wastes are not generated basically during production, the produced ethylene diamine tetraacetic acid disodium powder is pure white, purity is 99.8% or more, and quality is stable.
