一般描述
二甲基亚砜(DMSO)是极性溶剂。由亲电子试剂(草酰氯)活化的 DMSO,已用于氧化各种醇(伯、仲、烯丙基、苄基、受阻和双环)。形成羰基化合物作为反应产物。由于具有较高的稳定性,已被推荐为甲基纤维素溶剂在茚三酮反应中的替代溶剂。
应用
- Modification of gelatin by reaction with 1,6-diisocyanatohexane.: This study focuses on the modification of biopolymers using chemical agents, which could be relevant in contexts where DMSO is used as a reaction solvent ( Bertoldo et al., 2007).
- Characterization of O-acetyl-(4-O-methylglucurono)xylan isolated from birch and beech.: This research characterizes specific wood-derived xylans, potentially enhancing understanding of such biopolymers when dissolved in DMSO for analytical studies ( Teleman et al., 2002).
注意
在室温下容易过冷并缓慢重融。 固化产品可以通过加热至室温来重新液化,而不会损害产品。
