    Abstract: Provided is a method for preparing a hydrophobic silica aerogel by using a Soxhlet extraction, and a hydrophobic silica aerogel prepared by using the method. Since the preparation method according to the present invention may simultaneously perform washing and drying of a hydrophobic silica wet gel as well as solvent substitution and may remove an extraction solvent without an additional separation process, a hydrophobic silica aerogel having low tap density and high specific surface area may be easily prepared.

    Abstract translation: 提供了通过使用索氏提取法制备疏水性二氧化硅气凝胶的方法和使用该方法制备的疏水性二氧化硅气凝胶。 由于根据本发明的制备方法可以同时进行疏水性二氧化硅湿凝胶的洗涤和干燥以及溶剂置换，并且可以在没有另外的分离过程的情况下除去萃取溶剂，具有低振实密度和高比表面积的疏水性二氧化硅气凝胶 区域可以容易地准备。
