On the other hand, they are much weaker bases than the aliphatic amines, their salts undergoing hydrolytic dissociation in aqueous solution.
The aromatic aldehydes resemble the aliphatic aldehydes in most respects, but in certain reactions they exhibit an entirely different behaviour.
The aromatic amines in some respects resemble the aliphatic amines, since they form salts with acids, and double salts with platinum chloride, and they also distil without decomposition.
The aromatic amine resembling the aliphatic amines is benzylamine, C6H5.
Aliphatic monobasic acids are further divided according to the nature of the parent hydrocarbon.
CH3, in chemistry, the simplest representative of the aliphatic ketones.
When heated with the halogens, acetophenone is substituted in the aliphatic portion of the nucleus; thus bromine gives phenacyl bromide, C6H6CO.
It is convenient to distinguish between aliphatic and aromatic acids; the first named being derived from open-chain hydrocarbons, the second from ringed hydrocarbon nuclei.
Thus primary alcohols and aldehydes, both of the aliphatic and aromatic series, readily yield on oxidation acids containing the same number of carbon atoms.
It is convenient to restrict the term to compounds in which the hydroxyl group is attached to an aliphatic residue; this excludes such compounds as the hydroxy-benzenes, naphthalenes, &c.
The sulphonic acid group may also be directly introduced either by concentrated, or by fuming sulphuric acid, or by elimination of halogen by the action of sodium or silver sulphite on the halogen derivatives of the aliphatic compounds.
The characteristic distinctions which exist between aliphatic and benzenoid compounds make the transformations of one class into the other especially interesting.
In the first place we may notice a tendency of several aliphatic compounds, e.
These observations may be summarized by saying that the benzene nucleus is more negative in character than the aliphatic residues.
It has already been stated that benzene derivatives may be regarded as formed by the replacement of hydrogen atoms by other elements or radicals in exactly the same manner as in the aliphatic series.
The fifth compound, on the other hand, does not behave as an unsaturated aliphatic compound, but its deportment is that of a nucleus, many substitution derivatives being capable of synthesis.
OH, where R is an alkyl radical, either aliphatic or cyclic in nature.
In general, the aliphaticresidues in such mixed compounds retain the characters of their class, while the aromatic residues retain the properties of benzene.
We now proceed to discuss the types of aliphatic compounds; then, the characteristic groupings having been established, an epitome of their derivatives will be given.
The first four substances are readily formed from, and converted into, the corresponding dihydroxy open-chain compound; these substances are truly aliphaticin character.
Mixed aromatic-aliphatic amines, both secondary and tertiary, are also more strongly basic than the pure aromatic amines, and less basic than the true aliphatic compounds; e.
COOH, the first member of the series of aliphaticmonobasic acids of the general formula CnH(2n)O2.
CHO, the first member of the series of saturated aliphatic aldehydes.
The esters of the aliphatic amino acids may be diazotized in a manner similar to the primary aromatic amines, a fact discovered by T.
The first aliphatic diazo compound to be isolated was diazoacetic ester, CH.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "aliphatic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
