摘要： A method for producing a silica aerogel includes a gelation step of adding a monoalkyltrialkoxysilane to an acidic aqueous solution containing a surfactant to prepare a sol, and then gelating the sol to prepare a wet gel. The method further includes a separation step of immersing the wet gel in a solvent mixture of a first solvent and a second solvent immiscible with the first solvent to move the surfactant contained in the wet gel to a phase of the second solvent while moving the wet gel to a phase of the first solvent. The first solvent has an E T N value of 0.5 or less, and the second solvent has an E T N value between those of the first solvent and water. The method further includes a drying step of drying the wet gel having moved to the phase of the first solvent in the separation step at a temperature lower than a critical temperature of the first solvent under a pressure lower than a critical pressure of the first solvent to remove the first solvent from the wet gel.
