Phosphorus is objectionable because in similar circumstances it produces phosphoric anhydride and phosphoric acid.
2
This refrigerator is like those which we employ in our sulphurous anhydride frigorific apparatus.
3
Several smaller runs of 25 g. of phthalic anhydride gave the same percentage yield.
4
The Company is also engaged in the production and research and development of acetic anhydride.
5
This matter has been fully discussed in connection with the phosphoric anhydride determination.]
6
Chromic anhydride is a very strong oxidizing agent, giving up oxygen and forming chromic oxide:
7
Acetic anhydride converts the base into an acetamino-dimethyl pyrimidine, acetic acid and acetamide being also formed.
8
When distilled with phosphoric anhydride they yield nitriles.
9
The anhydride, prepared by a simple one-step synthesis, is added as the solid to the solid protein.
10
It can also be synthesized by heating catechol with phthalic anhydride and sulphuric acid at 150 deg.
11
The synthesis strategy of these new huperzine A derivatives is based on a condensation with an acyl anhydride.
12
In twenty-four hours a small concentrating plant was erected, and a ditch made to drain off the carbonic anhydride in the valley.
13
The chemical name of this product is "polymerized oxybenzyl methylene glycol anhydride," but nobody calls it that, not even chemists.
14
But the results might, on the other hand, be considered indicative of the anhydride or 'lacton' grouping, which Tollens suggested for lævulose:
15
These results are especially significant because maleic acid, in the form of maleic anhydride, is widely available and produced in large quantities annually.
16
This substance when heated to 100°C., or higher, is completely dehydrated, leaving only the anhydride, SiO_{2}.
