in resolution of 1-phenylethalamine after filtering tartrate salt of the resolved amine,we wash the crystal with small amount of cold methanol.what is the most important compound we are removing by this?
Homework Answers
This resolution results two salts, (+)-amine (+)-tartrate and (−)-amine (+)-tartrate. 1-phenylethalamine also exist in two forms namely prismatic ((−)-1-phenylethylamine (+)- tartrate) and needle like crystals ((+)-1-phenylethylamine (+)- tartrate), but the needles dissolve more easily than the prisms in warm methanol. Hence the prismatic ((−)-1-phenylethylamine (+)- tartrate) salt can be crystallized out of methanol solution.
what is the most important compound we are removing by this?
Answer: prismatic ((−)-1-phenylethylamine (+)- tartrate)
Hope this helped you!
