    • Provided is a fatty acid chloride which is manufactured by a simple method, which does not cloud and which has stable color over time. A fatty acid chloride is produced by causing a fatty acid with a carbon number of 8-22 and phosphorous trichloride in a proportion of one-third to two-thirds with respect to the fatty acid to react and removing phosphorous acid that appears as a byproduct to obtain a reaction product. Next, the reaction product is treated at a temperature of 10-60°C, a nitrogen flow rate of 1.0 × 10 -4 to 1.0 × 10 -2 m 3 /kg·hr, and a pressure of 133.3 X 10 -2 to 133.3 × 10 2 Pa, the unreacted phosphorous trichloride is caused to react with the fatty acid and the fatty acid chloride to produce an organic phosphorous compound, and the unreacted phosphorous trichloride is distilled to obtain the fatty acid chloride.
    • 本发明提供一种通过简便的方法制造的不会变色且随着时间的推移色彩稳定的脂肪酰氯。 通过使相对于脂肪酸的碳原子数为8〜22的脂肪酸和三氯化磷的比例为三分之一至三分之二以反应并除去作为副产物出现的亚磷酸而生成脂肪酸氯化物 得到反应产物。 接着,在10〜60℃的温度,1.0×10 -4〜1.0×10 -2 m 3 / kg·hr的氮气流量,133.3×10 -2〜 133.3×10 2 Pa,使未反应的三氯化磷与脂肪酸和脂肪酰氯反应生成有机磷化合物,蒸馏未反应的三氯化磷得到脂肪酰氯。

    • The present invention discloses 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt in different crystal forms and the preparation methods thereof, and belongs to the field of pharmaceutical chemistry. Said different crystal forms of 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt include: amorphous 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt, crystal form A of 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt, and crystal form B of 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt. The different crystal forms of 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt obtained according to the present invention have better stability and water-solubility than the mixed forms of 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt, thus is advantageous for pharmaceutical use. Moreover, the different crystal forms of 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt possess much better therapeutic effect than 5-bromo-2-(±-hydroxypentyl)benzoic acid potassium salt.
    • 本发明公开了不同晶型的5-溴-2-(± - 羟基戊基)苯甲酸钠盐及其制备方法,属于药物化学领域。 所述不同晶型的5-溴-2-(± - 羟基戊基)苯甲酸钠盐包括:无定形5-溴-2-(± - 羟基戊基)苯甲酸钠盐,5-溴-2-( ± - 羟基戊基)苯甲酸钠盐和5-溴-2-(± - 羟基戊基)苯甲酸钠盐的晶型B. 根据本发明获得的5-溴-2-(± - 羟基戊基)苯甲酸钠盐的不同晶体形式比5-溴-2-(± - 羟基戊基)苯甲酸的混合形式具有更好的稳定性和水溶性 酸性钠盐,因此对于药物使用是有利的。 此外,5-溴-2-(± - 羟基戊基)苯甲酸钠盐的不同晶体形式具有比5-溴-2-(± - 羟基戊基)苯甲酸钾盐好得多的治疗效果。
