Uses
It is used for organic synthesis intermediates and solvents.
Production
Add 3 - Methyl -2 - furan carboxylic acid to dry quinoline with copper powder as catalyst.Heated to about 250 ℃, quinoline was boiling, the reaction of carbon dioxide escaping.Reaction for the distillation process,that was 3 - methyl-furan , the yield of about 85%.
