    名称:
    Examining the robustness of a theophylline cocrystal during grinding with additives
    摘要:
    通过一系列含有不同官能团的共形成物的溶剂滴研磨实验,评估了茶碱-对羟基苯甲酸共晶(TP·pHBA)与添加剂在固态研磨时的稳健性。粉末 X 射线衍射用于对研磨后的粉末进行定性分析并鉴定存在的物质。发现 TP·pHBA 共晶在苯甲酸 (BA)、对硝基苯甲酸 (pNBA)、对 (N,N-二甲氨基) 苯甲酸 (dMABA)、间羟基苯甲酸 (mHBA) 的存在下具有稳定的稳定性、对硝基苯酚 (pNP)、氢醌 (HDQ) 和苯甲酰胺 (BZA),但在水杨酸 (SA)、3,5-二硝基苯甲酸 (dNBA)、乙酰胺 (ACA) 和三聚氰胺 (MLM) 存在下会分解。
