It burns with a purple flame, forming carbon dioxide and nitrogen; and may be condensed (by cooling to - 25° C.) to a colourless liquid, and further to a solid, which melts at - 34.4° C. (M.
It may be condensed and yields a solid which melts at - 55° C. Sulphuretted hydrogen decomposes it with formation of hydrofluoric acid and liberation of sulphur.
Winckler's own views are condensed in the 3rd edition - a re-writing - of Schrader's work (Keilinschr.
He expressed in an eager, disjointed, but condensed and laboured fashion, certain deep-lying convictions - that philosophy must come back from unsubstantial metaphysics to the solid facts of human nature and natural science, that the human body was no less important than the human spirit ("Der Mensch ist was er isst") and that Christianity was utterly out of harmony with the age.
A further generalization was effected by August Kekule, who rejected the hydrochloric acid type as unnecessary, and introduced the methane type and condensed mixed types.
Such condensed nuclei are, in many cases, more readily obtained than the parent nucleus.
Thiophene yields a similar series: isothiazole (only known as the condensed ring, isobenzothiazole), thiazole, diazosulphides, piazthioles, azosulphimes and thiobiazole (the formulae are easily derived from the preceding series by replacing oxygen by sulphur).

The apparatus consists of three parts: - the "retort" or "still," in which the substance is heated; the "condenser," in which the vapours are condensed; and the "receiver," in which the condensed vapours are collected.
In the Linnemann column the condensed vapours temporarily collect on platinum gauzes (a) placed at the constrictions of a bulbed tube.
- In this process a current of steam, which is generated in a separate boiler and superheated, if necessary, by circulation through a heated copper worm, is led into the distilling vessel, and the mixed vapours condensed as in the ordinary processes.
- In this process the substance operated upon is invariably a solid, the vapours being condensed and collected as in the other methods.
In its simplest form the apparatus consists of a straight tube, made of glass, porcelain or iron according to the temperature required and the nature of the reacting substances, heated in an ordinary combustion furnace, the mixture entering at one end and the vapours being condensed at the other.
Vancouver lies in a region of extensive forests and of fruitgrowing and farming lands; among its manufactures are lumber products, barrels, condensed milk, flour, beer and canned f_uit.
Finally, we condensed everything on a small computer thumb drive which we hid in the removable base of a desk lamp.
The third and concluding volume, which was to treat in a more condensed form the principal problems of practical philosophy, of philosophy of art and religion, never appeared.
Soden lozenges (Sodener Pastillen), condensed from the waters, are also in great repute.
The former of these has the entire text, but no plates; the latter reproduces the plates, but the text is in places much condensed, and excellent notes are added.
This may be brought about by a distillation under pressure, or by allowing the condensed distillate to fall into the highly heated residue in the still.
In order to separate the distillate into various fractions, and to remove as much of it as possible free from condensed steam, it is now usual to employ condensing appliances of special form with outlets for running off the different fractions.
The distinction between algebraical and arithmetical reasoning then lies mainly in the fact that the former is in a more condensed form than the latter; an unknown quantity being represented by a special symbol, and other symbols being used as a kind of shorthand for verbal expressions.
All their endeavours have obtained at best but a doubtful success, for they have overlooked the fact that to evaporate a given weight of water from the syrup in a vacuum pan at least an equal weight (or in practice about 15% more) of steam must be condensed, and the first cost of mechanical agitators, together with the expenditure they involve for motive power and maintenance, must be put against the slight saving in the heating surface effected by their employment.
This work was abridged by Bleek for his college lectures, and was published in that condensed form in 1868.
The aeration of the water is effected by blowing air into the steam before it is condensed; as an auxiliary, the storage tanks have a false bottom perforated by fine holes so that if air be injected below it, the water is efficiently aerated by the air which traverses it in fine streams. After condensation the water is filtered through charcoal.
Boron chloride BC1 3 results when amorphous boron is heated in chlorine gas, or more readily, on passing a stream of chlorine over a heated mixture of boron trioxide and charcoal, the volatile product being condensed in a tube surrounded by a freezing mixture.
The mono-amino derivatives or eurhodines are obtained when the arylmonamines are condensed with orthoamino zo compounds; by condensing quinone dichlorimide or para-nitrosodimethyl aniline with monamines containing a free para position, or by oxidizing ortho-hydroxydiaminodiphenylamines (R.
At a time when many encyclopedias have capsulated and condensed important knowledge, the 11th edition is generally much more in-depth and thorough on its topics.
This gigantic nebulous mass, of which the sun was only the central and somewhat more condensed portion, is supposed to have a movement of rotation on its axis.
It seemed to Herschel that he was thus able to view the actual changes by which masses of phosphorescent or glowing vapour became actually condensed down into stars.
Pliny, relying wholly on characters taken from the feet, limits himself to three groups - without assigning names to them - those which have " hooked tallons, as Hawkes; or round long clawes, as Hennes; or else they be broad, flat, and whole-footed, as Geese and all the sort in manner of water;foule " - to use the words of Philemon Holland, who, in 1601, published a quaint and, though condensed, yet fairly faithful English translation of Pliny's work.
In the American petroleum refineries it is found that sufficient cracking can be produced by slow distillation in stills of which the upper part is sufficiently cool to allow of the condensation of the vapours of the less volatile hydrocarbons, the condensed liquid thus falling back into the heated body of oil.
The passage quoted is obviously a condensed quotation of the Roman Creed, which reappears also in the following (de Virg.
In the same way, by electrolysing a mixture of a metallic salt and an ester, other nuclei may be condensed; thus potassium acetate and potassium ethyl succinate yield CH 3 * CH2 ï¿½ CH2 ï¿½ C02 C2H5.
Mommsen in Monumenta Germaniae Historica: Auctores Antiquissimi, xii., 1894 condensed English translation by T.
The clouds of steam condensed to copious torrents, which, mingling with the fine ashes, proiced muddy streams that swept far and wide over the plains, aching even to the foot of the Apennines.
Distillare, more correctly destillare, to drop or trickle down), an operation consisting in the conversion of a substance or mixture of substances into vapours which are afterwards condensed to the liquid form; it has for its object the separation or purification of substances by taking advantage of differences in volatility.
A condenser so placed that the condensed vapours return to the distilling flask, a device permitting the continued boiling of a substance with little loss; W.
Three types of columns are employed: (I) the elongation is simply a straight or bulb tube; (2) the column, properly termed a "dephlegmator," is so constructed that the vapours have to traverse a column of previously condensed vapour; (3) the column is encircled by a jacket through which a liquid circulates at the same temperature as the boiling-point of the most volatile component.
At ordinary temperatures it is a gas, but may be condensed to a liquid which boils at - 6° C. It has a strong ammoniacal smell, burns readily and is exceedingly soluble in water.
Ruff and Curt Albert (Ber., 1905, 38, p. 53) by decomposing titanium fluoride with silicon chloroform in sealed vessels at 100 -120° C. It is a colourless gas which may be condensed to a liquid boiling at -80 2° C. On solidification it melts at about -110° C. The gas is very unstable, decomposing slowly, even at ordinary temperatures, into hydrogen,, silicon fluoride and silicon: 4SiHF 3 =2H 2 +3SiF 4 +Si.
Wailer (Ann., 1857, 104, p. 94), is formed by heating crystallized silicon in hydrochloric acid gas at a temperature below red heat, or by the action of hydrochloric acid gas on copper silicide, the products being condensed by liquid air and afterwards fractionated (0.
Bernthsen (Ann., 1884, 224, p. 1) condensed diphenylamine with fatty acids, in the presence of zinc chloride.
