Tartrate → Tartrate maleate

참여 물질

반응 단계

In the production of HOPTC and DOOHC it is preferred that calcium D, L-tartrate and monosodium maleate slurry obtained from the tartrate/maleate removal step is added to the calcium maleate while heating to a boil at atmospheric pressure. The mixture is held at boiling for about 15 minutes to ensure conversion of all of the calcium carbonate to the maleate. The mixture is then charged to the synthesis reactor for the preparation of additional HOPTC and DOOHC. During transfer to the synthesis reactor water may be evaporated to reduce volume.
