  • Solvent-Substitution Solvent Used in Aerogel Production, and Hydrophobised Aerogel Production Method Using Same
    Publication number: 20150141532
    Abstract: Provided are a solvent-substitution solvent for producing a hydrophobized aerogel and a method for producing a hydrophobized aerogel. The solvent-substitution solvent includes pentanol in an amount of 41 wt % to 100 wt % and n-butanol in an amount of 0 wt % to 59 wt %. The method includes performing a solvent substitution process using the solvent-substitution solvent. If the solvent-substitution solvent is used for solvent substitution and/or hydrophobization in an aerogel production process, water (moisture) contained in a wet gel may be effectively substituted with the solvent-substitution solvent, and the solvent-substitution solvent may easily be collected at a high degree of purity and may be reused if necessary. Therefore, the rate of solvent loss may be minimized.
