Condensation apparatus

Using the microwave Just decreased the reaction time to 3-30minutes. The dudes in the article used a household, 500W Brazilian microwave (Yikesl). They cut a whole in the top of the microwave to allow the condenser apparatus to pass through the oven. They then killed themselves most likely. But not before they were able to scratch down this procedure as they slowly burned to death ...

The outlay in the construction of each furnace is said to be four hundred and fifty francs, or about eighteen pounds fifteen shillinge, of which sum sixteen pounds thirteen shillings are paid for the cap, the balance being ample for constructing the body of the furnace. The condensing apparatus is not included in this statement. 

Pig, 40 is a eide elevation of this arrangement, represented, for want of space, as broken off in the middle, a is one of the four furnaces, a motion of which, along the lino X, is shown ih Fig. 41 and Fig. 42 is a plan of the platforni, is, on the top of the furnaces, with part of the condensing apparatus attached. The same letters in each of the figures indicate corresponding parts,... 

Most experiments of this kind require efficient apparatus for condensing the products of reaction owing to the high temperature it is generally advisable to pass these first through an empty flask and then through some efficient type of condenser. The condensing apparatus may be attached to the exit end of the combustion tube by means of a cork and delivery tube, or the exit end of the combustion tube may be bent and drawn out after the shape of an adapter.

A similar experiment was reported by RJ. Dougan et al. [90], A set-up called Qn-line Separation and Condensation AppaRatus (OSCAR) was installed at the LBNL 88-Inch Cyclotron. Nuclear reaction products were collected with a KQ aerosol gas-jet and were transported from the target chamber to the OSCAR set-up where 02 was added. The aerosol particles were destroyed on a hot quartz wool plug and the formation of tetroxides occurred at a temperature of 650°C. Non volatile reaction products were retained on the quartz wool plug whereas the volatile tetroxides were swept by the carrier gas flow to a condensation chamber, where they were deposited on a Ag disk, which was cooled with liquid N2. An annular Si... 

Watt to Black, 3 February 1783, in Robinson and McKie (eds), Partners in Science, pp. 121-2 on p. 122. Richard Hills informs us of Watt s puzzlement in 1770 by the great amount of air in his condensing apparatus and that in his early engines he made ample provision for the removal of air and water with triple pumps . (See Hills, James Watt. Volume 2, p. 220.)... 

If large quantities are to be distilled, a condenser is always used, since when other condensation apparatus is employed, the tube finally becomes so hot that the vapours are not completely condensed. If the vapours of a substance attack corks, the outlet tube is inserted far enough into the condenser or extension tube...

The purification system comprises a horizontal still along with a dephleg-mating and condensing apparatus. The chlorinated benzene is heated by steam coils and refluxed until the system is warm. The vapors are then drawn through a tall column to the condenser by a vacuum pump. The first fraction consists of benzene and water. The second fraction (sp gr, 1.090-1.108 at 15 C) is impure chlorobenzene and is added to the batch next to be distilled. The chlorobenzene fraction (sp gr, 1.108 at 15 C) is then run into separate containers. The presence of p-dichlorobenzene in the distillate is indicated by a sudden increase in the density of the distillate. This point is watched closely to prevent contamination of the principal product. 

As a rule, closed furnaces use more fuel and cost more for labour than open ones (reverberatory), which, on the other hand, lose more antimony through volatilisation and oxidation than closed ones. This loss can, however, be eliminated by the use of the condensation apparatus of Herrenschmidt, to be mentioned later. 

The inevitable loss in tubes an-J in reverberatory furnaces can be prevented by using the condensation apparatus of Herrenschmidt. 

According to M. Herrenschmidt, the tiioxide produced by the volatilisation method can be reduced in the following way —An ordinary reverberatory furnace furnished with condensing apparatus, as shown in fig. 52, is previously heated before the following charge is commenced —... 

The solutions required are iodic acid, 50 grms. in 250 c.c. deci-normal sodium thiosulphate 20 per cent, potassium iodide and starch paste. Into the flask of a Fresenius or Mohr s iodometric apparatus, 0-5-0-6 gramme of antimonious oxide is weighed, 20-25 c.c. of iodic acid are added, and 10 c.c. of potassium iodide solution are placed in the condensing apparatus. The contents of the flask are boiled until colourless, and the collected iodine determined with thiosulphate. From antimony compounds the sulphide is precipitated by sulphuretted hydrogen, then dissolved in HCl, and the oxide obtained by the action of sodium carbonate. The halogen acids, sulphurous acid, and sulphuretted hydrogen must be dissolved in...
