| 摘要 |
<p>Proposed are two variants of a method for producing 4-ADPA and alkylated derivatives thereof using a new catalytic system which includes a base, such as hydroxides of alkali or alkaline earth metals, and aliphatic heterochain polyethers such as ethers of polyethylene glycol (PEG), of polypropylene glycol (PPG), of polytrimethylene oxide (PTMO), or of polytetrahydrofuran, or PEG monomethyl ethers, PPG monobutyl ethers, etc., or block copolymers thereof, such as PEG-PPG-PEG, PEG-PPG-PPG, PEG-PPG-PTMO, or a statistical polymer (PEG-PPG), having a mass ratio of hydroxide to polyether of 1:5-20 respectively.</p> |
