    • 1-Hydroxy-2-Bromo-3-Allyloxypropane (allyl glycidyl ether bromohydrin) and 1-hydroxy-2-bromo-3-allyloxypropane phophoric acid ester (allyl glycidyl ether bromophosphate), which are useful as polymerizable flame-retardants, are described. 1-Hydroxy-2-bromo-3-allyloxypropane was prepared by the reaction of equimolar amounts of allyl glycidyl ether and hydrobromic acid, in acetic acid, preferably at a temperature in the range of 25.degree.-50.degree. C. and the thus obtained allyl glycidyl ether bromohydrin was phosphated by reaction with a substantially equimolar amount of polyphosphoric acid, preferably at a temperature in the range of about 40.degree.-50.degree. C., to produce the 1-hydroxy-2-bromo-3-allyloxypropane phosphoric acid ester.
    • 描述了可用作聚合性阻燃剂的1-羟基-2-溴-3-烯丙氧基丙烷(烯丙基缩水甘油醚溴代醇)和1-羟基-2-溴-3-烯丙氧基丙烷磷酸酯(烯丙基缩水甘油醚溴磷酸酯) 。 通过等摩尔烯丙基缩水甘油醚和氢溴酸在乙酸中反应制备1-羟基-2-溴-3-烯丙氧基丙烷,优选在25〜50℃的温度范围内,由此获得 烯丙基缩水甘油醚溴代醇通过与基本上等摩尔量的多磷酸反应而磷酸化,优选在约40-50℃的温度下磷酸化,得到1-羟基-2-溴-3-烯丙氧基丙烷磷酸 酯。
