There are three isomers of toluidine, which are organic compounds.These isomers are o-toluidine, m-toluidine, and p-toluidine, with the prefixed letter abbreviating, respectively, ortho; meta; and para.All three are aryl amines whose chemical structures are similar to aniline except that a methyl group is substituted onto the benzene ring. The difference between these three isomers is the ...Weber 7106 grill cover

Jun 01, 2006 · The synthesis of N-(2-hydroxy-3-methoxybenzyl)-N-p-tolylacetamide is a fast, simple three-step sequence that serves as a useful example of the reductive amination reaction for the organic chemistry laboratory. The first step is a spectacular solvent-free solid-solid reaction between ortho-vanillin and para-toluidine to synthesize an imine in quantitative yield. The imine is reduced to an amine ...

This type of vanillin is differing from ordinary vanillin (4-hydroxy-3-methoxybenzaldehyde) where the hydroxyl group is in the para-position. Many researches have been used 4-hydroxy-3-methoxybenzaldehyde (vanillin) to synthesize of transition metal complexes with hydrazone ligands but less research using ortho-vanillin.

Weigh a 250 mL beaker and then add 0.76 grams (5 mmol) of ortho-vanillin to one side of the beaker. Record the total mass of the beaker plus the ortho-vanillin. Using weighing paper, accurately weigh an equivalent amount of para-toluidine (0.535 grams, 5 mmol) and add this to the opposite side of the beaker.
