On fluid chlorine

Abstract

By exposing the solid hydrate of chlorine, hermetically sealed up in a glass tube, to a temperature of about 100, the chlorine is evolved from it under such pressure that it assumes the liquid form, appearing of a bright yellow colour, and sinking in the warm water without showing any tendency to mix with it till the temperature fell to about 70°, when the whole re-assumed the appearance of solid hydrate. The liquid chlorine, in its pure form, did not congeal at 0°, and it instantly assumed its usual elastic form upon removing the pressure to which it was subjected. By condensing dry chlorine by means of a syringe into a glass tube, Mr. Faraday succeeded in converting a portion of it into a liquid, under a pressure of about four atmospheres. The specific gravity of liquid chlorine he considers to be about 1·33.
