Abstract
PURPOSE: To obtain a mixture of halogenated unsaturated alcohol and ester which are useful as raw materials for the synthesis of organic acetylene compounds, etc., by irradiating a mixture of an aliphatic monocarboxylic acid ester and a halogenated ethylene with ionizing radiation.
CONSTITUTION: A mixture of a halogenated unsaturated alcohol of formula III (R2 and R3 are H or alkyl; X1W-X3 are halogen) and a halogenated unsaturated ester of formula IV (R1 is H or alkyl) is obtained by irradiating a mixture of an aliphatic monocarboxylic acid ester of formula I and a halogenated ethylene of formula II (X4 is halogen) with 1W100Mrad of ionizing radiation of a radioisotope such as cobalt-60 at ordinary temperatureW200°C for 10W1,000hr. The molar ratio of the ester of formula I to the halogenated ethylene of formula II is 100:1W1:10. The content of the halogenated unsaturated ester in the product decreases and that of the alcohol increases when the reaction temperature is increased. When the irradiation time is longer, the yield is higher.
USE: Perfumes, raw materials of polymers, flame-retardents, agricultural chemicals, etc.
