摘要:
The present invention relates to a process to crystallize a chelating agent containing a step of adding seeds to a saturated or supersaturated aqueous solution or dispersion of the chelating agent and a subsequent step of milling the dispersion, wherein the step of milling the dispersion is performed using equipment operating at at least 1,000 rpm, and to products obtainable by such process.
摘要:
L'invention concerne un procédé de préparation d'un sel d'acide acétylsalicylique et d'un acide aminé basique, comprenant le mélange dans un réacteur d'une solution d'acide acétylsalicylique et d'une solution dudit acide aminé basique, à une température inférieure ou égale à 30 °C à pression atmosphérique. Ce mélange est réalisé par introduction progressive dans le réacteur, simultanément, de quantités instantanées équimolaires d'acide acétylsalicylique et de l'acide aminé basique.
摘要:
The present invention relates to a new crystalline phase of (3S,3S') 4,4'-disulfanediylbis(3-aminobutane 1-sulfonic acid) (ABSD) with L-lysine and its use, particularly in the pharmaceutical industry, and to processes for preparation thereof. The invention is also directed to pharmaceutical compositions containing at least one crystalline phase of (3S,3S') 4,4'-disulfanediylbis(3-aminobutane 1-sulfonic acid) (ABSD) with L-lysine and to the therapeutic or prophylactic use of such crystalline phase and compositions comprising the same.
摘要:
Provided is a method for preparing stable free flowing solid aminocarboxylate chelants by adding to a chelant that contains residual alkaline metal hydroxide a free or partially neutralized carboxylic acid such that the free or partially neutralized acid neutralizes at least a portion of the alkaline metal hydroxide; and isolating therefrom the free-flowing solid chelant.
