Multi-diethylene glycol, diethylene glycol more than two halide, the dual acidbrine, or salt, and other non-hydroxy-carboxylic acid ring for the start of raw materials, the elements within or between Central elements of the response is the type of crown more lactone Common methods. This paper studies in Al-Mg-based compound under the conditions of the catalyst, epoxy paraffin embedded ¦Ã-butyrolactone (GBL) by the extended one-step reaction lactone synthesis of ether, the synthesis of novel, simple steps . And in the response explorations add template, the template used lactone synthesis of ether.![]() ![]() |
