苯并噁嗪化合物的合成及固化

Synthesis and solidification of dibenzoxazine

以甲醛,苯胺,苯酚为原料合成苯并口恶嗪.研究了加料次序、催化剂的选择、反应时间及各种固化因素.最后制得红棕色无定型态的固状物———苯并口恶嗪聚合物,其分子量为5.495X105.

Dibenzoxazine is synthesized from formaldehyde,aniline and phenol.The order of material addition,the selection of catalyst,the reaction time and the factors of solidification are studied.In the end the brown indefinite solid matterdibenzoxazine is prepared,and its molecular weight is 5.495×105.
