Plastic used in polyurethane production of toluene diisocyanate Determination of total chlorine content Warning. This standard except with the specific safety requirements related to the trial, the use of this standard should also have a general knowledge of laboratory safety and health protection. Toluene diisocyanate absorbed through the skin or inhaled vapors harm to the body, the test procedure should be ventilated and take appropriate precautions.1 ScopeThis standard specifies the method for measuring the oxygen bomb method and oxygen flask combustion method toluene diisocyanate in total chlorine. This standard applies to the determination of the production of polyurethane toluene diisocyanate in total chlorine.2 Normative referencesThe following documents for the application of this document is essential. For cited documents with dates, only the dated edition applies to this document. For undated references, the latest edition (including any amendments) applies to this document. Preparation of GB/T 601 chemical reagent standard titration solution Laboratory use specifications and test methods GB/T 6682 Analysis Principle 3 The samples of organic matter and oxygen combustion destruction of organic chlorine into inorganic chlorine, chlorine ions by automatic potentiometric titrator titration with standard silver nitrate solution. Method A is an oxygen bomb method, the sample under pressure in the oxygen bomb combustion. Method B is an oxygen flask combustion method, the sample at atmospheric pressure oxygen bottle combustion.4 InterferenceBromide and iodide ions may be reacted with a silver nitrate solution, resulting in higher total chlorine content. 5 Method A --- bomb method 5.1 instruments and equipment 5.1.1 Ignition Wire. 34. 5.1.2 oxygen bomb calorimeter. the oxygen bomb, ignition unit, the inner cylinder, an outer cylinder combustion bowl and other components. Oxygen Bomb technical parameters are as follows. a) Capacity. 300mL; b) the oxygenation pressure. 2.0MPa ~ 3.0MPa; c) pressure resistance pressure. 20MPa; d) Quality. 2.5kg ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 32477-2016_English be delivered?Answer: Upon your order, we will start to translate GB/T 32477-2016_English as soon as possible, and keep you informed of the progress.
