On the other hand, they show faintly acid properties since the hydrogen of the amide group can be replaced by metals to give such compounds as mercury acetamide (CH3CONH)2Hg.
In the case of Scenedesmus acutus it is said that the alga is unable to take up nitrogen in the form of a nitrate or ammoniacal salt, and requires some such substance as an amide or a peptone.
Guanidine may be formed by the action of oxidising agents, such as potassic chlorate and hydrochloric acid, on guanine; or by heating amide cyanide with ammonium chloride, and so forming guanidine chloride.
Of, pertaining to, or designating, an acid which is the primary acid amide derivative of tartaric acid.
Of, pertaining to, or designating, an acid amide derivative of succinic acid, obtained as a white crystalline substance, and forming a series of salts.
The amidethus obtained was oxidized as described by Remsen (loc.
The yield in amide melting above 153° was a little over one sixth the weight of toluene used.
The amide obtained in this way was oxidized in the manner already described.
The amide which separated from these extracts was perfectly white and melted at 153-5°.
It was found however that there was always some benzoic p-sulphamide in the solution of the oxidation, due to the slight admixture of p- with the o-amide used.
If the heat is too high a large amount of a tarry product is formed and the yield of amide is correspondingly small.
This salt, in parting under various conditions with ammonia, carbonic anhydride, and water, does not present a constant composition, and ought rather to be regarded as a mixture of acid salt and amide salt.
Thus urea, both by its origin and decomposition, is an amide of carbonic acid.
Judging from the increase in weight of the sodium and the quantity of hydrogen which is disengaged, the composition of the amide is exactly NH{2}Na.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "amide" in a variety of sentences. We hope that you will now be able to make sentences using this word.
