It is recommended to add methanol and boric acid for direct esterification to generate trimethyl borate.

Add compatibility with "FTB Quests". For example, the Quests can detect the reactions occurring in the reactor and the generated substances. Also, when I write quests using "FTB Quests", not only can I not directly take the target substances that need to be synthesized as the quest requirements, but I also can't find a good way to guide players to look at the recipes in JEI in the quest interface. So I suggest adding a new item. By naming this item the structural formula of the corresponding substance (just like the format written in nbt), it can be regarded as a molecule on JEI, and the formula can be directly viewed (the appearance is also best changed accordingly). If some functions cannot be implemented in Destroy, Please remind me to submit my suggestions to FTB Quests.

Please separate multiple suggestions into separate posts in future. I don't mind people making a bunch at once.

There is some boron chemistry which will be revised in future.

I think FTB Quests would have to implement compatibility with JEI's Generic Ingredients for what you are describing to happen, if that is not already possible (I'll look into it briefly). A richer tutorial-like system similar to FTB Quests is planned for down the road though.
