The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and
the standard EN 374 derived from it.
Body Protection
impervious clothing, Flame retardant antistatic protective clothing, The type of protective
equipment must be selected according to the concentration and amount of the dangerous
substance at the specific workplace.

制备方法与用途

在装有加料口的三口反应瓶中，依次加入四氢呋喃溶液、4-溴-1-丙基-1H-吡唑及频哪醇硼烷，并将两者溶解于350 mL四氢呋喃中。随后，将反应液冷却至-10℃，缓慢滴加正丁基锂的四氢呋喃溶液（共175 mL），并在室温下反应12小时。

之后，在反应液中加入300 mL氯化铵水溶液并搅拌30分钟。接着，加入400 mL乙酸乙酯，分出有机层，并用无水硫酸钠进行干燥。经过过滤、蒸干滤液后，残余物通过体积分数为20%的乙醇重结晶得到产物1-丙基-1H-吡唑-4-硼酸频哪醇酯。
