A selection of the most common extraction techniques are listed in Table 1. Each of the techniques will then be discussed, detailing what is involved to set up the equipment, the advantages and disadvantages as well as some of the limitations of each technique. The primary aim of any extractable study is the acceptance or rejection of a given material. The acceptance or rejection can only be achieved with knowledge. This can be achieved by a number of ways, including; understanding of the materials likely composition, manufacturers information and the definitive testing. In all aspects of extractable testing it is important to remember that the extraction is not so vigorous as to deform or degrade the material which would likely produce extractables that will not be observed as leachables. Extractables are potential leachables, it is the leachables that the patient is exposed to and are of toxicological concern.

  • Improved Automatic Steam Distillation Combined with Oscillation-Type
    Lachenmeier et al. SpringerPlus (2015) 4:783 DOI 10.1186/s40064-015-1574-6 METHODOLOGY Open Access Improved automatic steam distillation combined with oscillation‑type densimetry for determining alcoholic strength in spirits and liqueurs Dirk W. Lachenmeier1* , Leander Plato1, Manuela Suessmann1, Matthew Di Carmine2, Bjoern Krueger3, Armin Kukuck3 and Markus Kranz3 Abstract The determination of the alcoholic strength in spirits and liqueurs is required to control the labelling of alcoholic bev- erages. The reference methodology prescribes a distillation step followed by densimetric measurement. The classic distillation using a Vigreux rectifying column and a West condenser is time consuming and error-prone, especially for liqueurs that may have problems with entrainment and charring. For this reason, this methodology suggests the use of an automated steam distillation device as alternative. The novel instrument comprises an increased steam power, a redesigned geometry of the condenser and a larger cooling coil with controllable flow, compared to previously available devices. Method optimization applying D-optimal and central composite designs showed significant influ- ence of sample volume, distillation time and coolant flow, while other investigated parameters such as steam power, receiver volume, or the use of pipettes or flasks for sample measurement did not significantly influence the results. The method validation was conducted using the following settings: steam power 70 %, sample volume 25 mL trans- ferred using pipettes, receiver volume 50 mL, coolant flow 7 L/min, and distillation time as long as possible just below the calibration mark. For four different liqueurs covering the typical range of these products between 15 and 35 % vol, the method showed an adequate precision, with relative standard deviations below 0.4 % (intraday) and below 0.6 % (interday).

Synthesis of Ni2P nanoparticles. Caution: Because this procedure involves the high-temperature decomposition of a phosphine that can liberate phosphorus, this reaction should be considered as highly corrosive and flammable, and therefore should only be carried out by appropriately trained personnel using rigorously air-free conditions. Ni(acac)2 (250 mg, 0.98 mmol) was added to a 50-mL three-necked, round bottom flask containing a borosilicate stir bar. The flask was also equipped with a thermometer adapter, thermometer, Liebig condenser, and rubber septum. Prior to sealing the flask, 1-octadecene (4.5 mL, 14.1 mmol), oleylamine (6.4 mL, 19.5 mmol), and tri-n-octylphosphine (2 mL, 4.4 mmol) were added to the vessel.

For the decomposition of iodide of amyl he resorted to the use of zinc-amalgam in powder in sealed tubes at a temperature a little above that of the boiling-point of the liquid. He thus obtained, not zinc-amyl but a mixture of three hydrocarbons, viz., amyl, CloH,,, a light liquid boiling at 155" ; hydride of amyl, C5H12,an exceedingly mobile liquid with an agreeable odour, boiling at 30" ; amylene, C,H,,, another limpid liquid boiling at 35", and combining with fuming sulphuric acid. It appeared to us therefore a point of special interest to ascertain whether our copper-zinc couple was capable of effecting the decompo- sition of amyl iodide with production of an organo-metallic body.

When the water turns into a gas, the salt remains behind in the flask. 2. Liebig condenser | Liebig condensor | condensor | condenser 3 marks Explanation: The Liebig condenser has a straight inner tube that the warm condensing vapour passes through. The outer tube has cooling water passing through it. In this way the warm vapour cools down and condenses back into a liquid. 3. B: distillation 4 marks Explanation: Distillation is a method used to separate a mixture of a dissolved solid (eg. salt) and a liquid (eg. water). When the mixture is heated (no 15 in diagram), the liquid turns into a gas, is cooled down by the Liebig condenser (no 5 in diagram) and turned into liquid water, which is collected into a separate container (no 8 in diagram). 4. A: distillate 4 marks Explanation: The water which is collected in the beaker during distillation is called the distillate. The distillate is pure water. 5. sieves | a sieve 3 marks Explanation: Sieves were used to separate the two solid substances. The sand fell through and the gold ore remained behind. 6. physical 3 marks Explanation: A mixture is made up of two or more materials with different physical properties, like sand and water. Because they have different properties, they can be separated from one another. Get more content at www.worksheetcloud.com Page 1 of 2 Copyright Learning Lab Apps (Pty) Ltd.
