overview | amine extractants have high chemical stability, low price and easy availability, and can overcome phosphorus-containing and oxygen-containing extractants The shortcomings of high water solubility or poor selectivity. The amine extractant triisooctylamine has been widely used as an extractant. In addition, it can also be used as an intermediate in organic synthesis. |
Application area | High molecular weight amines were first used as extractants by Smith and Page in the 1980s. Triisooctylamine is mainly used as extractant and organic synthesis intermediate. 1. Extraction of uranium and plutonium [4] The nuclear industry wastewater often coexists with uranium and bad, and most of them are monitored by a single determination method. However, if combined determination can be used, the number of pretreated samples can be reduced, thus saving a lot of manpower and material resources and improving monitoring efficiency. The liquid anion exchanger TIOA (triisooctylamine) has the advantages of large partition coefficient and small impurity influence ability, so it is widely used in the extraction of radioactive metal elements in nuclear waste. 2. Extraction of trace platinum [9] Studies have shown that Pd(II),Rh(III), Ir(III), Au(III) and Pt(IV) are extracted from hydrochloric acid and hydrobromic acid with 5% carbon tetrachloride solution of triisooctylamine. The extract of gold from hydrochloric acid is yellow and absorbed at 325nm. The palladium compound is red and absorbs at 290nm and 467nm. Platinum compounds are blood red and absorb at 268nm. Finally, the quantitative results show that triisooctylamine can extract platinum from waste liquid and separate it from other metals. 3. extraction of free mercury [2] Zheng Haijin et al. studied the behavior and mechanism of microemulsion separation of mercury (II) composed of nonylphenol polyoxyethylene ether (OP-10), isoamyl alcohol, cyclohexane and NaOH aqueous solution with triisooctylamine (TIOA) as carrier. The effects of carrier triisooctylamine, external phase hydrochloric acid, KBr and internal phase NaOH on the extraction rate of mercury (II) at different concentrations were investigated respectively. Studies have shown that Hg(II) can be completely separated from them in the presence of coexisting ions and the extraction behavior of each ion is basically the same as when it exists alone, so their extraction behavior in the mixture can be estimated according to the single extraction behavior of each ion. 4. extraction of gold [1,9] triisooctylamine has the advantages of strong extraction ability, low solubility in water, high enough chemical stability and gold in TIOA-toluene solution has a large distribution ratio, so it can be used to extract gold in acidic system. At the same time, TIOA-toluene system has high selectivity and good stability, so it can be used for quantitative analysis of gold content in waste liquid. |
production method | there is no preparation process of triisooctylamine in the current public literature. |
storage and transportation conditions | the substance is stable at normal temperature and pressure, and contact with strong oxidants is avoided during storage. Dangerous goods are packaged independently, with more than 5 liters of liquid or more than 5 kilograms of solid. EHS mark must be found on the outer package after the combination of each independent package outside and independent inner package. |
first aid measures | inhalation: if inhaled, please move the patient to fresh air. If breathing stops, perform artificial respiration. Consult a doctor. Rinse with soap and plenty of water. Consult a doctor. Eye contact: Rinse thoroughly with plenty of water for at least 15 minutes and consult a doctor. Intake: Never feed anything to the unconscious, rinse your mouth with water and consult a doctor. |
