摘要:本发明提供了一种色谱级沸程30-60的石油醚的制备方法,具体步骤为:(1)采用低含量的发烟硫酸在搅拌和控温0-10℃加入到工业级沸程30-60的石油醚中,其中,发烟硫酸与石油醚的质量比为1:8-12;(2)搅拌40-60分钟,水洗,弃去下部沉降物,得到上层液体;(3)30%NaOH水溶液调节PH至7-8并碱洗上层液体,去水后留上层清液在NaOH条件下分馏得到色谱级沸程30-60的石油醚;该方法所得色谱级沸程30-60的石油醚纯度高,工艺简单合理,产品合格率高,适合规模化工业生产的需要。

主权项:一种色谱级沸程30‑60的石油醚的制备方法,其特征在于:具体制备步骤如下:(1)采用低含量的发烟硫酸在搅拌和控温0‑10℃加入到工业级沸程30‑60的石油醚中,其中,发烟硫酸与石油醚的质量比为1:8‑12;(2)搅拌40‑60分钟,水洗,弃去下部沉降物,得到上层液体;(3)30%NaOH水溶液调节PH至7‑8并碱洗上层液体,去水后留上层清液在NaOH条件下分馏得到色谱级沸程30‑60的石油醚。
