Pàgina 258 - Turning next to the compounds formed by the union of the base and fluoride of silicon in the proportion of two molecules of the former to one of the latter...
Pàgina 169 - ... may belong to either the ethylene or the ethylidene series. An etheric normal olefine acid differs from a normal olefine acid only in having the hydrogen of the hydroxyl replaced by an organic radical positive or negative. A secondary olefine acid is one in which the atom of carbon united with oxalyl is not combined with hydroxyl, and in which the atom of carbon united with hydroxyl is also combined with two monatomic alcohol radicals. In the above formula К must he a monatomic alcohol radical.
Pàgina 166 - COHo. A normal acid of the lactic series may be defined as one in which an atom of carbon is united with oxalyl, hydroxyl, and at least one atom of hydrogen. In the above general formula for these acids R may be either hydrogen, or any alcohol hydrogen.
Pàgina 259 - AsI3 in the proportion of one molecule of the former to two of the latter : the two substances melt together to a deep-brown liquid, which, on cooling, solidifies to a dark gray crystalline mass. The crystals are homogeneous, tolerably hard and brittle, yielding a reddish-brown powder on pulverization ; they cannot be preserved in the air, as they lose all their iodine in...
Pàgina 3 - A com/pound organic radical is a group of atoms containing one or more atoms of carbon of which one or more bonds are unsatisfied ; and it is either a monad, dyad, fyc. radical, according to the number of monad atoms required to complete its active atomicity.
Pàgina 41 - ... their conversion for the greater part into carbonic anhydride and water, whilst at the same time relatively small quantities of acids of the CnH2n + 1(CO2H) and CnH2n(CO2H)2 series are produced. METHANE (methylic hydride ; marsh-gas ; light carburetted hydrogen ; fire-damp), CH4. Occurrence.
Pàgina 189 - Pyrosulphuric acid is formed from sulphuric acid by the abstraction of one molecule of water from two molecules of the acid: — ,0H SO.
Pàgina 170 - ... which an atom of carbon is united with oxalyl, hydroxyl, and two atoms of an alcohol radical. An etheric secondary acid stands in the same relation to a secondary, as an etheric normal does to a normal acid. A normal olefine acid is one in which the atom of carbon united with oxalyl is not united with hydroxyl, and in which the atom of carbon united with hydroxyl is combined with not less than one atom of hydrogen. In this formula R may be either hydrogen or a monatomic alcohol radical, and the...
Pàgina 23 - This gas is formed by the direct union of its elements, when the current from a powerful voltaic battery passes between carbon poles in an atmosphere of hydrogen.
Pàgina 171 - K must be a monatomic alcohol radical. An etheric secondary olefine acid is related to the secondary olefine acids in the same way as the etheric normal olefine acids are related to the normal olefine acids. The numerous cases of isomerism in the lactic series are next examined and explained ; and the authors then show how the radicals which are employed for the production of the synthesised acids may again be separated, thus affording...
