    With oxalic acid, glycerol at 503 K gives

    Solutions

    When glycerol is reacted with Oxalic acid at 383K, it gives formic acid as follows: CH2OH-CHOH-CH2OH + COOH-COOH ------> CH2OH-CHOH-CH2OH + HCOOH at 383K .The glycerine is used in excess amounts and hence obtained in products also. But when , it is heated with Oxalic acid at 503K, it gives allyl alcohol, i.e. those alcohols in which OH group attached to carbon is sp3 hybridised but the sp3 hybridised carbon is attached to sp2 hybridised carbon atom.Allyl alcohol is CH2=CH-CH2OH.
