WebAug 1, 1997 · TMA is clearly the main product when equilibrium is approached. At 400 and N/C= 1, the M/D/T molar split (MMA/DMA/TMA molar ratio) is 17/21/62. At high MeOH conversion where equilibrium is approached, TMA is the major product; however, world demand is very different with DMA being the most desired product.
