摘要：

Silica-based aerogels containing L-lactic moiety were synthesized by a cogelation procedure of tetramethoxysilane (TMOS) with lactate-modified aminopropyltrimethoxysilane L-CH3CH(OH)CO -NH -(CH2)(3)Si(OMe)(3), followed by supercritical drying (SCD). Lactate-modified silica aerogels are semitransparent yellowish monoliths possessing high specific surface area (up to 340 m(2)/g). L-lactate-contaMing lyogel and aerogel possess the optical activity inherent to L-lactic acid derivatives. (C) 2016 Elsevier Inc. All rights reserved.
