Patent Office) is a guarantee that the monoacetic acid ester of salicylic acid in these tablets is of the reliable Bayer manufacture.
It is also obtained by condensation of diethylcyanacetic ester with urea by means of sodium alcoholate.
It is detected by heating with ordinary alcohol and sulphuric acid, which gives rise to acetic ester or ethyl acetate, recognized by its fragrant odour; or by heating with arsenious oxide, which forms the pungent and poisonous cacodyl oxide.
Of foremost importance are the reactions termed the malonic acid and the aceto-acetic ester syntheses; these are discussed under their own headings.
Paal has also obtained pyrrol derivatives by condensing acetophenone-aceto- acetic-ester with substances of the type NH2R.

We may note here that an important item in the quantitative factors of the cellulose nitric ester reaction has been overlooked: that is, the yield calculated to the NO{3} groups fixed.
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.
The numbers resulting from the quantitative study of the ester reaction and product (1st ed.
A similar series was carried out with the guncotton in the condition in which it was directly obtained from the ester reaction.
In practice it is not necessary to combine the saponification of cellulose ester with complete reduction of the nitric acid split off.
The bodies causing instability are products or by-products of the original ester reaction, acid bodies containing nitroxy-groups, but otherwise of ill-defined characteristics.
They confirm the probability of the occurrence of secondary changes in the ester reactions.
It will be shown that the ester groups can be actually localised in various ways, as in the main entering the cellulose residues alpha and beta.
In this respect again there is a close parallelism between the sulphocarbonate and benzoyl-ester reactions.
Tollens points out that the results of empirical analysis are inconclusive; and that from the acid reactions of these products and their combination with bases, carboxylic groups are present, though probably in anhydride or ester form.
PbO are associated with acid products or by-products of the ester reaction combining with the oxide, the lead reagent was allowed to react in the presence of 90 p.

It is one of the best suggestions that that dear Ester has given us.
I ought to have called in that dear sister Ester to help on this phase of the question before.
I thought so then, little fellow that I was, and I think so now, only nobody is at work carrying them out; and I wonder sometimes if Ester could have been needed in heaven half as much as she is needed on earth.
Ester was never well enough to undertake it; nor could she seem to enlist any one else in such service.
They are henceforth to be known as THE ESTER RIED BAND.
An accident to one of his family held him for several weeks in the town where this Ester Ried lived; and her physician, with whom he became acquainted, introduced him to her.
Ester had wanted him to grow up to undertake just such efforts as these; and only last week they had seemed to him so altogether good and noble and so impossible to try.
Might it possibly be that this was one of the "helpers" of whom Ester used to talk, sent by God himself to take up her planned work and follow it out?

Ester was particularly anxious that no one should suppose her experience exceptional.
It was the morning after you had told me that about Ester Ried.
If the Republicans won, Bismarck should not be guillotined; if the monarchists, d'Ester should not be hung.
They fell into conversation, and d'Ester suggested that they should make a compact and, whichever party succeeded in the struggle for power, they should each agree to spare the other.
Configuration of the Benzene Complex); the condensation of acetone dicarboxylic ester with malonic ester to form triketohexamethylene dicarboxylic ester (E.
CO2C2H5, formed by condensing acetic ester with formic ester, and also its dimolecular condensation product, coumalic acid, readily yields esters of [1.
Isobutyric acid is found in the free state in carobs (Ceratonia siliqua) and in the root of Arnica dulcis, and as an ethylester in croton oil.
In washing the layer of ethyl phenylacetate with sodium carbonate it is sometimes advisable to add a certain amount of sodium chloride so that the ester will separate more readily.
If it is found to contain sufficient benzoic acid to react with a considerable proportion of the sodium alcoholate, a poor yield of ester will be obtained.
Left to herself, Ester found her train of thought so thoroughly disagreeable that she hastened to rid herself of it, and seized upon the new comer to afford her a substitute.
Naturally, Ester had expected that the young creature, so suddenly shorn of her best and dearest, would falter and faint, and utterly fail.

Ester knew that Mrs. Ried had been with her daughter for a few moments, and that Ralph had rushed in and out again, too overcome to stay, but Ester had asked no questions, and received no information concerning her.
