Distinction between Chemistry and Alchemy in Arabic and Farsi languages

Question

According to Wikipedia, in Europe the semantic distinction between the rational science of chimia and the occult alchimia arose in the early 18th century. So it seems like there was a need to separate these terms with the advancement of scientific practices and the term chemistry (with the Arabic article "al-" dropped) came to refer to the scientific practice while alchemy came to refer to the older non-scientific practice.

Turkish language in 19th century followed a different path by shifting the meaning of a completely different esoteric practice, sīmiya¹ (letter magic), to be used in place of esoteric/old chemistry and by keeping the word kīmiya as the scientific/modern chemistry.

I am wondering if similar semantic changes/shifts happened in Arabic and Farsi languages, but could not find any information since I do not speak/read these languages and the online sources I found regarding the etymology of the word mostly focus on European languages.

¹ "Sīmiya" (derived from Ancient Greek sema σήμα: "sign", "symbol") is etymologically unrelated to "kīmiya" (either derived from the ancient Egyptian khem/khm, meaning "blackness" or derived from the Greek χημεία, meaning "cast together").

Answer 1

Kimiya (کیمیا) is the Persian word for the attempt of turning tin and copper to silver or gold, or finding the elixir.

Today in Persian, Kimiya is only used in a metaphoric sense in the literature for unreachable, and shimi (شیمی) derived from the French la chimie is used to refer to the scientific branch.
