<p>精制方法:于环丁砜中加入粒状氢氧化钠进行蒸馏,或用柱高1.5m,装有玻璃填料的蒸馏塔进行减压蒸馏。</p> | |
<p>由于热稳定性高,对酸、碱稳定,是一种优良的溶剂。可用于从脂肪烃中萃取芳香烃,从气体混合物中除去酸性气体。环丁砜可用作高分子化合物如聚丙烯腈、丙烯腈共聚物、聚氟乙烯等的溶剂,用于纺丝,制造胶片等。还可用作纤维素醚、聚乙烯醇、聚乙烯、聚氯乙烯、聚酰胺等的增塑剂,丙烯酸纤维纺丝的添加剂。其他还可用于脂肪酸的分离,从木材中萃取非纤维素成分等。由于环丁砜沸点高,热稳定性好,无腐蚀性,可用作冷凝器载体。添加到压榨机油中可以改进耐腐蚀性、防燃性、热稳定性、黏度等性质。</p> |
