Abstract
Chloral alcoholate is prepared by chlorinating ethyl alcohol in a continuous manner by flowing ethyl alcohol through a plurality of vessels arranged in series while continuously introducing chlorine into each of said vessels below the surface of the liquid therein, separately controlling the temperature in each vessel, the first vessel in the series being maintained at a temperature not substantially above atmospheric and collecting the reaction product which overflows from the last vessel in the series. The subsequent vessels are preferably maintained at higher temperatures. In the example, an apparatus consisting of two vessels in series is used, the first vessel being half the capacity of the second and each vessel being provided with a stirrer, a means of controlling the temperature and an outlet through a reflux condenser for hydrogen chloride. The first vessel is filled with alcohol saturated with chlorine at room temperature and the second with alcohol previously chlorinated to crude chloral alcoholate. Alcohol and chlorine are fed continuously into the first vessel whilst the overflow from this vessel and chlorine at twice the rate in the first vessel are fed into the second vessel, the contents being heated. The product may be treated with concentrated sulphuric acid to produce chloral or it may be reacted with benzene or a halo- or nitro-derivative thereof in the presence of concentrated sulphuric acid as described in Specification 573,044. Specification 17202/00, [Class 2], also is referred to.
