制备方法与用途

简介

4-硝基-2-(三氟甲基)苯甲酸为白色至淡黄色晶体粉末，密度1.596克/立方厘米，沸点321.4°C（760毫米汞柱），熔点138-142°C（文献值）。该化合物可通过多种合成路线制备。

用途

4-硝基-2-(三氟甲基)苯甲酸作为羧酸类衍生物，主要用作医药及农药中间体。

制备

在三口瓶中加入5克2-三氟甲基苯甲氰，然后滴加10毫升硝化剂。将温度升至70°C，并以磁力搅拌器搅拌3小时后结束反应。随后加入30毫升水进行分液处理，取有机层。对水层使用30毫升乙酸乙酯萃取一次，合并有机相并用无水硫酸钠干燥。通过旋蒸得到6.5克固体产物，即4-硝基-2-(三氟甲基)苯甲酸。

  Attachment Behaviors, Depression, and Anxiety in Nonoffending Mothers of Child Sexual Abuse Victims

  摘要：

  本研究的目的是研究未参与虐待的儿童性侵受害者（CSAVs）的母亲的心理幸福感和依恋行为。这个主题很重要，因为通常是母亲最经常为年幼的受害儿童提供支持。分析了关于母亲抑郁症、状态和特质焦虑以及Ainsworth母亲依恋行为的两组数据。首先，根据母亲是否有虐待史，比较了38位CSAVs的母亲。其次，从最初的38位CSAVs的母亲中，比较了27位母亲与一组非受虐儿童的母亲。两组数据中的儿童年龄为6至48个月。在第一组数据中，根据母亲个人虐待史，抑郁症、焦虑和依恋行为没有显著差异。然而，在第二组数据中，CSAVs的母亲抑郁和焦虑水平升高，母亲依恋行为减弱。
