Similarly he represented the reactions investigated by Liebig and Wohler on benzoyl compounds as double decompositions.
The monobenzoate and dibenzoate are formed by benzoyl chloride reacting on alkali-cellulose (see below).
Benzamide, C6H5CONH2, is prepared by the action of benzoyl chloride on ammonia or ammonium carbonate, or from ethyl benzoate and ammonia.
Pharmacologically it acts as a urinary antiseptic and diuretic; the benzoyl derivative, cellotropin, has been used for tuberculosis.
These statistics further confirm the localisation of the benzoyl group in the cellulose residue.
With the two benzoyl groups converted into nitro-benzoyl in each product, the limit of the ester reaction with the cellulose residue is reached at the third OH group.
From these results it would appear that the number of acetyl groups entering the benzoates is the same as with the unbenzoylated fibres, the benzoyl has no influence upon the hydroxyls as against the acetyl.
NaOH, and subsequently with benzoyl chloride, gives about 50 p.
The analysis of the products points to the entrance of 1 NO{2} group in the benzoyl residue in either case; in the cellulose residue 1 OH readily reacts.
It is to be noted that the presence of the benzoyl group renders the cellulose more resistant to hydrolytic actions.
The mixed nitrate from the benzoate is denitrated to a cellulose amidobenzoate, which confirms the localisation of a nitro-group in the benzoyl residue.
This solution, shaken with benzoyl chloride, with addition of sodium hydrate in successive portions, shows only a small formation of insoluble benzoate, which separates as a tarry precipitate.
Compounds which contain two amido groups combined with one and the same carbon atom, do not yield benzoyl derivatives when shaken with benzoyl chloride and soda.
The best method of separating putrescine is thebenzoyl chloride method already given.
It can be made synthetically by the reaction of ecgonin-methyl-ester with benzoyl chloride.
Garcia[660] has attempted to trace the rates at which they are formed by allowing meat extracts to decompose, precipitating by benzoyl chloride (see p.
Ethyl benzoate may be employed instead of benzoyl glycollic acid for this reaction.
An alternative method consists in converting it into ethyl benzoate by shaking with benzoyl chloride and caustic soda.
With sodium ethylate in ethyl acetate solution it forms the sodium derivative of benzoyl acetone, from which benzoyl acetone, C6H5.
H2O which is probably an oxy-methoxy-benzoyl benzoic acid.
The next step was to arrest all the aristocrats who had not fled from the town, lock them up in the Grenier de Chantepoulet, and improvise a revolutionary tribunal to judge them.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "benzoyl" in a variety of sentences. We hope that you will now be able to make sentences using this word.
