The rapid determination of acetic acid and acetic anhydride in diketene by infrared spectrometry

Fast and Sensitive Determination of Acetic Anhydride in the Air Using Hollow Fiber Method

This study aimed to introduce a new method based on Hollow Fiber in order to determination of acetic anhydride (AA) in the air. Hydroxylamine hydrochloride and sodium hydroxide (1:1), were used as extraction solvent. This method was studied in the laboratory under various conditions. In order to make different concentrations of AA in the air, a standard glass chamber was used. The optimization ...

The Action on Tyrosine and on Phxnylamino- Acetic Acid of Acetic Anhydride and Acetone in the Presence of Pyridine

There are recorded in literature several instances in which the acylation of amino acids in the presence of pyridine proceeded abnormally. ’ We have encountered an unexpected reaction in attempting to acetylate I-tyrosine suspended in. a solution of pyridine in commercial acetic anhydride (containing 90 to 95 per cent of the pure anhydride). From the reaction product a orystalline substance, CM...

Acetic Acid in Cholera

The treatment of cholera by acetic acid, suggested by Dr. Greene in the September number of the Indian Medical Gazette, deserves, I think, to be put to the test by the profession. When I perused Dr. Greene's article, it struck me that, from its strong antiseptic property, acetic acid may do good by counteracting the morbific influence of the cholera miasm in the blood. Besides, being a stimulan...
