| titleOfInvention |
Dehydrohalogenation of poly (phenylhalo-b-hydroxypropyl ether) to form polyepoxide |
| abstract |
Process for the preparation of compounds of the formulawherein Hal represents chlorine, bromine or iodine and preferably chlorine, wherein Ra represents hydrogen or a residue comprising one or more additional groups of the formula,from compoundswherein R2 represents hydrogen or a residue comprising one or more additional groups of the formulaby reaction with gaseous hydrogen halide in the presence of a catalytic amount of an organic acid;process for the preparation of epoxy compounds starting from the reactionto produce a compound of formula (III) which is converted to a compound of formula (A) that is dehydrohalogenated to form the epoxy rings of a diepoxy compound. |
