【摘要】 以 9,1 0 -二氢 -9-氧杂 -1 0 -磷杂菲 -1 0 -氧化物 (简称DOP)为起始原料 ,用两种方法合成了新型阻燃剂 [( 6-氧 -( 6H) -二苯并 -(c,e) ( 1 ,2 ) -氧磷杂己环 -6-酮 )甲基 ]-丁二酸 (简称DDP)。热失重分析表明该化合物具有较高的热稳定性更多还原

【Abstract】 Using 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide(DOP for short) as raw materials, a new flame retardant [(6-oxide-6H-dibenz(c,e)(1,2) oxaphosphorin-6-yl)methyl] -butanedioic acid(DDP for short)was synthesized by two methods in this paper. Thermal gravimetric analysis showed that the compound exhibited better thermal stability.更多还原
