anhydrides

Robbins in this area brought out the existence of a new class of chemical compounds, the mixed anhydrides between phosphate and sulphate; adenosine-5'-phosphosulphate (APS) and

Thus with the direct ester reactions the normal fibrous cellulose (C_ {6} H_ {16} O_ {5}) yields a monoacetate, dibenzoate, and a trinitrate respectively under conditions which determine, with the simple hexoses and anhydrides, the maximum esterification, i.e. all the OH groups reacting.

In the case of phosphorus, arsenic, and antimony the oxides are acid anhydrides.

~ Like the corresponding oxides of phosphorus, the oxides of arsenic are acid anhydrides.

The iron is soon melted by the flame directed upon it, and the sulphur, phosphorus, and silicon are oxidized by the iron oxide, forming oxides which are anhydrides of acids.

The paper contains a large number of quantitative results in proof of the various points established, and concludes with elaborate tables, giving the equivalents in the known pentoses and their anhydrides for any given weight of phloroglucide from 0.050 to 0.300 grm.

From the characteristic property of yielding furfural, which they have in common with the pentoses, they have been assumed to be the anhydrides of these C_ {5} sugars or pentosanes; but the direct evidence for this assumption has been shown to be wanting.

Being nonvolatile, it will drive out most other anhydrides when heated to a high temperature with their salts, especially when the silicates so formed are fusible.

They also lay stress upon the superior stability of the nitrates of the anhydrides, especially of the ketoses.

The relation of these acids to the corresponding anhydrides may be illustrated as follows, phosphorus being taken as an example:
