SDS Volume (3067)

Volume 67. Halogenated Ethanes and Ethenes with Water, p 413

Original Measurements

Bell, R. P.; J. Chem. Soc. 1932, 2905-11.

Variables:

Room Temp: 288 - 298 $\pu{K}$

Prepared by:

A.L. Horvath

Method/Apparatus/Procedure:

An mixture of water and tetrachloroethene of about 1 to 5 volume ratio was placed in a sample vessel and rotated in a thermostat for 12 hours. After the equilibrium attained, samples were taken and filtered through cottonwool. The determination of the water content was based upon the reaction with $a$-naphthoxydichlorophosphine. The evolved $\ce{HCl}$ gas was absorbed in water and titrated with $\ce{NaOH}$ solution [1]. Two to three successive determinations were carried out with the samples.

Source and Purity of Materials:

1. Distilled (compiler).
2. Commercial reagent, fractionated three times before use, BP = 124-125&#deg;C.

Estimated Errors:

Ambient temperature: ±0.02 K.
Mass concentration (m/v) (1): ±3.5% mean dev.
