Process for the preparation of 2,2'-oxydisuccinate |
| abstract |
ABSTRACT A process for the preparation of 2,2'-oxydisuccinate is disclosed which utilises a combination of a low reaction temperature and a minimum excess of calcium hydroxide to an organic reactant. The use of a non reactive alkali metal salt of a strong or weak acid in the reaction mixture allows somewhat higher ratios of calcium hydroxide to reactant and somewhat higher temperatures. 2,2'-oxydisuccinate is produced in about 5 hours while gelation of the reaction mixture is substantially minimized. |
