IV <br />(Chem <br />1 MATERIAL SAFETY DATA SHEET ' <br />Potassium Amyl Xanthate (PAX) Solution <br />Ph: 10.5 -12.5 <br />SECTION 10 - STABILI7YAND REACTIVITY <br />Stability: PAX solutions are relatively stable iF they are kept cool and the pH is maintained within <br />an acceptable range. Under certain conditions, potassium amyl xanthate decomposes <br />to very toxic and extremely Flammable carbon disulfide. The rate of carbon disulfide <br />generation from solution increases with temperature, pH below 8 (becoming rapid <br />below pH Tx acidic conditions) or pH gnawer than 13, as well as with time (aging of the <br />solution). Maximum stability of solutions is attained at a pH of approximately 10. <br />Hazardous Polymerization: Does not occur <br />Hazardous <br />Decomposition Products: Decomposition products in water include carbon disulfide, trithiocarbonate, <br />pentanol, potassium carbonate. <br />Incompatibility: Adds or Acidic solutions - the hydrolysis of xanthate solutions, which produc <br />carbon disulfide, is accelerated by acidic pH (fess than 8) <br />Alkaline solutions (pH greater than 13) reacts to produce carbon disulfide, <br />hydrogen sulphide, n- pentanol, trithiounteriate and potassium carbonate. <br />Strong oxidizing Agents (e.g. peroxides, nitrates and peschlorates) - risk of fire and <br />explosion. <br />Metal Salts (e.g. copper, iron, lead or zinc salts) - accelerate the decomposition to <br />carbon disulfide. <br />SECTION 11- TOXICOLOGICAL INFORMATION <br />Oral: oral -Rat LD50: 1,000 - 2,000 mg/kg Intravenous -Mouse 11)50: 99 mg/kg <br />SECTION 12 - ECOLOGICAL INFORMATION <br />Environment If discharged to waterways, xanthates may persist for several days, <br />hydrolysing slowly in the neutral environment. Bioaccumulation is unlikely. Highly <br />to:dc to aquatic life. May form complexes with heavy metals, increasing their uptake, <br />i.e. fish may accumulate heavy metals more readily. <br />SECTION 13 - DISPOSAL CONSIDERATIONS <br />For small amounts, absorb with sand, vermioulite or similar and dispose of to an approved landfill site. For larger amounts, <br />contact the manufacturer for additional information. Prevent contamination of drains or waterways as aquatic life may be <br />threatened and environment damage may result. <br />Dispose of in accordance with relevant local Legislation. <br />SECTION 14 - TRANSPORTATION INFORMATION <br />Classified as Dangerous Goods by the criteria of the Australian Dangerous Goods Code (ADG Code) for Transport by road and <br />Rail. <br />Shipping Name: Corrosive Liquid Toxic N.o.S ' <br />UN Number: 2922 <br />Dangerous Goods Class. 8 CD3ROSIVE . `� <br />Dangerous Goods Sub Class: 6.1 , <br />Packing Group: ..
