Many people confuse Aliquat 336 (trademark of BASF) and Adogen 464 (trademark of Evonik) with methyl trioctyl ammonium chloride “MTOAC.” As we explain in our article from 2012, MTOAC is one of four quat salts in Aliquat 336 and Adogen 464.
MTOAC has a molecular weight of 404 g/mole versus 432 g/mole for Aliquat 336 and Adogen 464.
MTOAC has similar properties to Aliquat 336 and Adogen 464, but since MTOAC is one quat salt and not four quat salts, it may have several advantages depending on the application.
For example, it is easier to track the fate of MTOAC, a single quat salt, than a mixture of four quat salts. This may be important for certain applications and compliance with environmental regulations.
If the reactivity of a PTC application reaches maximum activity with a PTC quat that contains 25 carbon atoms or more, then MTOAC delivers 9% more quat than Aliquat 336 or Adogen 464 for the same mass of phase-transfer catalyst due to the difference in molecular weight.
One of our affiliates in Indiana (United States) has possession of 200 kg of MTOAC more than needed. If you are interested in purchasing this MTOAC (diluted in solvent), now contact Marc Halpern of PTC Organics and he will forward your inquiry to purchase this material.
