Please clarify the problem. There seem to be some unclear instructions and garbled parts in the content you gave (such as the expression "Dimethyl + Malonate + Mw", which is not clear about its exact meaning and purpose), so that I can better create an ancient essay classical Chinese according to your requirements. You can explain what this "Dimethyl + Malonate + Mw" stands for, and what are more specific ideas on the genre, word count, style, etc. of this ancient essay.
