The various factors influencing the yield of HCCH during the photochlorination of benzene.

The yield of HCCH depends on tho conditions employed during the
manufacture, An attempt is made on various factors such as time Of
chlorination, effect of temperature, addition of catalysts and solvents
influencing the yield of HCCH during the pbotochlorination of benzene,
Studies on the effec of time of chlorination revealed that the quantity of
HcCH increased as the time of chlorination increased, Benzene was cooled to
different temperatures and HCCH samples were prepared. ne results revealed
that the yield of HCCH decreased as the temperature was reduced.
Photochlorination of benzene was carried out in the presence of different
catalysts and the investigations revealed that the maximum yield of HCCH
was obtained when aluminium chloride was used as a catalyst during the
preparation. Benzene was diluted with various solvents like
carbontetrachloride, chloroform, methylene Chloride. ethylene dichloride and
ethyl acetate in different ratios and HCCH samples were prepared. The
maximum )field of HCCH was very poor when ethyl acetate was used as a
diluent during the photoChlorination of benzene.
