Im not sure I understand the question, so correct me if I'm wrong.
I'm guessing that English is not your first language, and you want to be able to understand chemical terms in English papers etc.?
If this is the case, I would reccommend looking for a "chemical dictionary" or "scientific dictionary" for your particular language. For example, I have a German chemical dictionary somewhere, in which I can look up German chemistry related words, and find the translation in English.
