Infra-red Absorption Spectrum of Fluoropyruvic Acid

Abstract: Mager and Blank1 have reported the synthesis of fluoropyruvic acid and claim that its infra-red spectrum shows an absorption band at 980 cm.−1, which they assign to the C—F stretching vibration. This frequency is outside the range normally assigned to this vibration2, and differs markedly from that suggested3 and afterwards found4 for this vibration in fluorocitric acid.

Detection and estimation of small amounts of impurities in the air.

Abstract: IN the course of measuring, in air, the surface potential change produced by the deposition of a monomolecular layer of fatty acid on a polished stainless-steel plate, transient changes of potential were observed, due to the passage over the plate of vapour impurities in the laboratory air. Some quantitative measurements of this effect have been made, particularly at low concentrations, thus extending the earlier work of Frost1,2.

Structure of Aluminium Soaps

Abstract: IN the course of a study of the water sorption of aluminium soaps, Shreve, Pomeroy and Mysels1 found that pure aluminium laurate which had been dried in vacuo over phosphorus pentoxide at room temperature gave 2·5 ± 0·4 per cent of water when examined with the Karl Fischer reagent. They maintained, consequently, that the reagent gives misleading results because, under the conditions of the determination, soap molecules react with each other, or with free acid, to give water, thus:

The Formation of an Aerosol by Condensation of a Dilute Vapour in a Carrier Gas

Abstract: The formation of a dilute aerosol by supercooling a mixture of vapour and carrier gas is examined theoretically. It is shown how the partial differential equations of this kind of problem can be reduced approximately to a set of ordinary differential equations, much more easily handled by numerical methods. An approximate solution is obtained which shows how the average particle size depends on the rate of cooling and the time of quenching.
