It yields a nitroso derivative, is nitrated by nitric acid to dilituric acid and brominated by bromine.
In truth therefore these attributes do not belong to body at all; and if we go on in the same way testing the received qualities of matter, we shall find that in the last resort we understand nothing by it but extension, with the secondary and derivative characters of divisibility and mobility.
It appears, however, to have been partly derived from yet earlier Tertiary deposits (Eocene); and it occurs also as a derivative mineral in later formations, such as the drift.
The Semitic name of the symbol is shin; the Greek name sigma may mean merely the hissing letter and may be a genuine Greek derivative from the verb o-4co, hiss.
With sodium ethylate in ethyl acetate solution it forms the sodium derivative of benzoyl acetone, from which benzoyl acetone, C6H5.CO.CH2.CO.CH3, can be obtained by acidification with acetic acid.
These fundamental truths are the causes or "reasons" (apxai) of all derivative facts.
Among the more recently introduced antiseptics, chinosol, a yellow substance freely soluble in water, and lysol, another coal-tar derivative, are much used.
In the same way it may be shown that three tri-substitution, three tetra-substitution, one penta-substitution, and one hexa-substitution derivative are possible.
Orientation of Substituent Groups.-The determination of the relative positions of the substituents in a benzene derivative constitutes an important factor in the general investigation of such compounds.
Not only does the substituent group modify the readiness with which the derivative is attacked, but also the nature of the product.
By further substitution of orthoand para-diderivatives, in general the same tri-derivative [1.2.4] is formed (Ann., 1878, 192, p. 219); meta - compounds yield [1.3.41 and [1.2.
Ladenburg's prism admits of one mono-substitution derivative and three di-derivatives.
Thus denotes a tetrahydro derivative in which the double link occupies the side 1; 0 a dihydro derivative, the double links being along the sides i and 3.
Cluded that in compounds the benzene nucleus appears to be capable of existence in two tautomeric forms, in the sense that each particular derivative possesses a definite constitution.
In certain derivative forms constituting the family Pallenidae, however, the appendages of the 2nd pair are either rudimentary or atrophied altogether.
Rosell, Ber., 1890, 23, p. 487), or from the aminoazo compound and a mustard oil, the resulting thiocarbanilido derivative being heated with acetic acid (M.
Busch (Ber., 1905, 38, pp. 856, 4049) has isolated a series of bridged ring compounds which he describes as endo-iminodihydrotriazoles, the triphenyl derivative (annexed formula) being prepared by condensing triphenylaminoguanidine with formic acid.
An important nucleus-synthetic reaction is the saponification of nitriles, which may be obtained by the interaction of potassium cyanide with a halogen substitution derivative or a sulphonic acid.
Weith, Ber., 1880, 13, 1300); or in the form of its acetyl derivative by heating /3-naphthol with ammonium acetate to 270-280° C. It forms odourless, colourless plates which melt at 111-112° C. It gives no colour with ferric chloride.
Fuming nitric acid gives a paratrinitro substitution derivative which on reduction gives paraleucaniline; the salt of the carbinol formed on oxidizing this substance is the valuable dye rosaniline.
Among derivative terms are "Phenomenalism" and "Phenomenology."
Amidotetrazotic acid yields addition compounds with amines, and by the further action of nitrous acid yields a very explosive derivative, diazotetrazol, CN 3.
The secondary value expresses the consonantal root of the name or other primary value, and any, or almost any, derivative from that root: as when ~ a mat with a cake upon it, is not only litp, an offering-mat, but also hip in the sense of conciliation, peace, rest, setting (of the sun), with many derivatives.
A similar series of reactions was carried out with rosaniline, which was shown to be the corresponding derivative of tolyldiphenylmethane.
The later derivative Yisra'eli, Israelite, from Yisra'el, is not found in the Old Testament.
A derivative word, Maruti or Maroti, is the popular name throughout the Deccan for Hanuman.
At the same time, and under the derivative influence of Wundt, rather than the more original inspiration of Fechner, W.
Such mentally endowed substances might be called souls; but, as he distinguished between perception and apperception or consciousness, and considered that perceptions are often unconscious, he preferred to divide monads into unconscious entelechies of inorganic bodies, sentient souls of animals, and rational souls, or spirits, of men; while he further concluded that all these are derivative monads created by God, the monad of monads.
