It separates in the form of small rose-red crystals, which decompose on boiling with water.
Helmond is one of the industrial centres of the province, and possesses over a score of factories for cotton and silk weaving, cotton printing, dyeing, iron founding, brewing, soap boiling and tobacco dressing, as well as engine works and a margarine factory.
OH N02(1.4), crystallizes in long colourless needles which melt at 114°C. Meta-nitrophenol, C6H4.OH N02 (1.3), is prepared from meta-nitraniline by diazotizing the base and boiling the resulting diazonium salt with water.
By heating the metal with chlorine, germanic chloride, GeCl4, is obtained as a colourless fuming liquid boiling at 86-87° C., it is decomposed by water forming a hydrated germanium dioxide.
On boiling their solution in caustic alkalis, ammonia is liberated.
They are violet-red in colour, and on boiling or long standing with dilute acids they pass into the corresponding roseo-salts.
It is a colourless fuming liquid boiling at 17-18° C., and is readily decomposed by water with formation of boric and hydrochloric acids.
(0C2H5)5 is obtained as a colourless liquid of boiling point 112° C. Boron triethyl and boron trimethyl both combine with ammonia.
To boiling point.
Cadmium sulphate, CdSO 4, is known in several hydrated forms; being deposited, on spontaneous evaporation of a concentrated aqueous solution, in the form of large monosymmetric crystals of composition 3CdSO 4.8H 2 O, whilst a boiling saturated solution, to which concentrated sulphuric acid has been added, deposits crystals of composition CdSO 4 4H 2 0.
They are not decomposed by boiling alkalis, but on heating with hydriodic acid they split into their components.
Pechmann, Ber., 18 9 5, 28, p. 857); by distilling anisic acid (paramethoxy benzoic acid) with baryta or by boiling phenyl diazonium chloride with methyl alcohol.
News, 1891, 63, p. 1); just above the boiling point the vapour is orange-yellow, but on continued heating it darkens, being deep red at 50o; at higher temperatures it lightens, becoming straw-yellow at 650°.
It is easily liquefied, the liquid boiling at - 8° C., and it becomes crystalline at - 72.7° C. (Walden, Zeit.
This salt may be prepared by digesting flowers of sulphur with sodium sulphite solution or by boiling sulphur with milk of lime.
Rictiovarus in disgust cast himself into the fire, or the caldron of boiling tar, from which they had emerged refreshed.
For piercing-mouthed pests like Aphides no wash is of use unless it contains a basis of soft soap. This softsoap wash kills by contact, and may be prepared in the following way: - Dissolve 6 to 8 lb of the best soft soap in boiling soft water and while still hot (but of course taken off the fire) add 1 gallon of questions involved, under their own headings.
The American "essence of spruce," occasionally used in England for making spruce-beer, is obtained by boiling the shoots and buds and concentrating the decoction.
It is a colourless liquid boiling at 197° 7 -198° 2 C. (W.
The industries are brewing, tanning, soap-boiling, flour-milling, malting, ironfounding, saw-milling and jam-making.
Crystals of a different form are deposited from a strong boiling solution of the acid.
It is soluble in 4ths of its weight of cold, and in half its weight of boiling water, and dissolves in alcohol, but not in ether.
The boiling point, being determined by the character of the constituents of the oil, necessarily varies greatly in different oils, as do the amounts of distillate obtained from them at specified temperatures.
The " cracking " process, whereby a considerable quantity of the oil which is intermediate between kerosene and lubricating oil is converted into hydrocarbons of lower specific gravity and boiling-point suitable for illuminating purposes, is one of great scientific and technical interest.
In preparing lead plaster by boiling olive oil with oxide of lead and a little water - a process palpably analogous to that of the soap-boilerhe obtained a sweet substance which, called by himself " Olsiiss " (" principium dulce oleorum "), is now known as " glycerin."
The cracking process practically consists in distilling the oils at a temperature higher than the normal boiling point of the constituents which it is desired to decompose.
It is soluble in alcohol, ether, chloroform and boiling water.
They form yellow or bronze-coloured crystals, which decompose on boiling their aqueous solution.
