摘要： The present disclosure provides a process for preparing iminodisuccinic acid salts using maleic anhydride, aspartic acid, and a base in water. In an example, maleic anhydride and aspartic acid are mixed with a base to form a slurry, preferably having a viscosity of about 1,000 cps or less. Preferably, the pH is raised to about 10 or above to achieve a homogenous clear solution. Water is distilled out increase the concentration of reactants. The solution is then heated to reflux, and the reaction allowed to proceed for a pre- determined time period. The present disclosure also provides a composition comprising about 35 wt% or less maleic anhydride, about 35 wt% or less aspartic acid, water, and a base, wherein said composition has a temperature of about 80°C or less, a pH of about 10 or greater and a viscosity of about 10000 cps or less.
摘要翻译： 本公开提供了使用马来酸酐，天冬氨酸和在水中的碱来制备亚氨基二琥珀酸盐的方法。 在一个实例中，将马来酸酐和天冬氨酸与碱混合以形成浆料，优选具有约1,000cps或更低的粘度。 优选地，将pH提高至约10或更高以获得均匀的澄清溶液。 蒸馏水可提高反应物的浓度。 然后将溶液加热回流，使反应进行预定时间。 本公开还提供了包含约35重量％或更少的马来酸酐，约35重量％或更少的天冬氨酸，水和碱的组合物，其中所述组合物具有约80℃或更低的温度，约为约 10以上，粘度约10000cps以下。

摘要： This disclosure relates to a method of managing a sulphur-containing species from a sour liquid, the method comprising: providing a sour liquid comprising sulphur-containing species; introducing a halogen-based catalyst to the sour liquid, the halogen-based catalyst being complexed with a second species; introducing an oxidant to the sour liquid; and reacting the sulphur-containing species, the halogen-based catalyst and the oxidant. The second species may be an ethoxylate or propoxylate species. The disclosure also relates to a composition comprising a sour liquid, a hydrogen-based catalyst complexed with a second species, and an oxidant, a use of a halogen-based catalyst that is complexed with a second species for the treatment of a sulphur-containing species in a sour liquid, and a composition containing a halogen-based catalyst that is complexed with a second species in a suitable carrier for use in the treatment of a sulphur-containing species in a sour liquid.
