    PROCESS FOR PRODUCING MEK-MODIFIED RESORCIN/FORMALIN RESIN PARALLELLY CARRYING OUT RECOVERY AND REUSE OF SPECIFIED RAW MATERIAL
    摘要:
    提供了一种用于生产MEK改性间苯二酚-甲醛树脂的特定原材料(MEK,甲醇和氯化钙)的回收和再利用方法。此外,通过部分改进生产步骤来控制MEK改性树脂中氯化钙浓度为100 ppm或以下,从而稳定质量是一个目标。在水溶剂中,加入间苯二酚,回收的氯化钙水溶液和回收的MEK并搅拌形成两相体系,然后加入盐酸催化剂,滴加甲醛到反应体系中,使液液异相反应进行。允许其静置分成两层,在去除水层(0)后,向MEK层(0)中加入水进行充分冲洗。然后允许其静置分成两层,并去除水层(1)。进行至少一次的此水洗操作以去除水层(2),从而获得含有MEK改性间苯二酚-甲醛树脂的MEK层(2)。向该MEK层中加入水,加入1至30%的氨水,通过精馏回收MEK,然后将其作为回收的MEK再次使用。此外,在通过减压蒸馏从水层(0)中去除甲醇后调整氯化钙浓度后,将水层再次返回到反应体系中并再次使用。通过这种闭环系统循环生产方法,最终获得反应产物浓度为30至80%,具有pH值为6至10的适度流动性,氯化钙浓度为100 ppm或以下,相对于凝胶渗透色谱分析所得到的整个峰面积,间苯二酚单体相应的峰面积为3至9%,五核或更高核体相应的峰面积为30至55%的间苯二酚-甲醛树脂水溶液。

    Compounds suitable for use in providing male contraception, an assay method for identifying such compounds, and methods of providing contraception using the compounds, are provided. In one embodiment, the compounds described herein mimic the binding of anti-EPPIN antibodies to EPPIN, and thus inhibit the forward motility of sperm in humans and other primates. In another embodiment, the compounds described herein inhibit or enhance EPPIN-semenogelin binding, and inhibit forward motility of sperm. The assays described herein identify compounds which inhibit sperm motility, and can be carried out in a high throughput manner, using labeled recombinant EPPIN and semenogelin. The compounds can be used in oral or transdermal compositions to temporarily and reversibly inhibit male fertility. They can also be used in addition to, or in place of, spermicides in spermicidal compositions, such as those used in conjunction with condoms, diaphragms, and spermicidal jellies.
    提供适用于提供男性避孕的化合物,用于识别此类化合物的测定方法,以及使用这些化合物提供避孕的方法。在一个实施例中,这里描述的化合物模拟抗EPPIN抗体与EPPIN的结合,从而抑制人类和其他灵长类动物的精子前向运动。在另一个实施例中,这里描述的化合物抑制或增强EPPIN-精浆蛋白结合,并抑制精子的前向运动。这里描述的测定方法识别抑制精子运动的化合物,并可以通过使用标记的重组EPPIN和精浆蛋白以高通量方式进行。这些化合物可以用于口服或经皮组合物,以暂时和可逆地抑制男性生育能力。它们也可以用于与避孕套、避孕膜和杀精子凝胶等杀精子组合物一起使用,或替代它们。
