Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus. THE APPLICATION OF TITRATION IN NON‐AQUEOUS MEDIA TO PHARMACEUTICAL ANALYSIS: P art I. T he D etermination of A lkali M etal S alts of A liphatic and A romatic A cids A. H. Beckett Pharmaceutical Chemistry Laboratories of the School of Pharmacy, Chelsea Polytechnic, London, S.W. 3Cited by: 7. Titrations in non-aqueous media. Part XIII. The titration curves of binary mixtures of histidine with diaminomonocarboxylic acids showed only one stoicheiometric end-point, corresponding to the sum of the four amino groups. The data obtained from the titrations in glacial acetic acid suggested that this solvent has a strong levelling effect. Non-aqueous Titrations INTRODUCTION. Boyle first recorded the insolubility of the water soluble salts in alcohol. In Folin and Flanders titrated the acidic substances by using the non-aqueous solvents such as benzene, chloroform and chloroform-methanol mixture. Conant and Hall in described the behaviour of bases in glacial acetic acid.

the non-aqueous titration of Bronsted acids and bases, a subject which has become of great importance in the analysis of pharmaceutical preparations. The BrSnsted acids and bases are protolytes, proton donors and proton. Non-aqueous Phase Titration Acid number is defined as the quantity of base, expressed as milligrams of potassium hydroxide per gram of sample, required to titrate a sample to specified end point. Here, spiking method 1 is used, because ASTM. Non Aqueous Titration Non aqueous titration refers to a type of titration in which the analyte substance is dissolved in a solvent which does not contain water. This procedure is a very important one in pharmacopoeial assays. Non Aqueous Titration Theory. Nonaqueous titration is the titration of substances dissolved in solvents other than water. It is the most common titrimetric procedure used in pharmacopoeial assays and serves a double purpose: it is suitable for the titration of very weak acids and very weak bases, and it provides a solvent in which organic compounds are soluble. The most commonly used procedure is the titration of organic bases with perchloric acid in anhydrous acetic acid.

London, Iliffe; Princeton, Van Nostrand, [i.e. ].   • Solvent which are used in non aqueous titration are called non aqueous solvent. • They are following types: 1. Aprotic Solvent 2. Protogenic Solvent 3. Protophillic Solvent 4. Amphiprotic Solvent 5. • Aprotic solvent are most important solvent in this titration. This solvent are chemically inert and they work as a catalyst. Thermometric titrations in non-aqueous media have a distinct advantage over the analogous aqueous system since all non-aqueous systems have a lower specific heat than the corresponding aqueous system. Hydrazine hydrochloride and some hydrazine derivatives were titrated potentiometrically with manganese(III) acetate in glacial acetic acid. The titrations were carried out both directly and indirectly. As the direct titrations are very time consuming, the indirect titrations were found to .
