Abstract
The present invention relates to a composite form of tetraacetylethylenediamine (TAED) and a method for its preparation. The composite form may comprise a new crystalline form. The invention also relates to the crystalline form itself. The present invention also relates to compositions comprising tetraacetylethylenediamine in these forms.
Claims24
A composite form of tetraacetylethylenediamine (TAED), said composite form comprising TAED and an ionic component, wherein said ionic component is a Deep Eutectic Solvent (DES).
A method of forming a composite form of TAED, the method comprising:
- a) heating TAED with deep eutectic solvent (DES) forming components, a DES solvent (DES), an Ionic liquid (IL) or a mixture thereof to a temperature≥150° C.;
- and
- b) allowing the mixture to cool to form the composite form of TAED.
A crystalline form of TAED (form III), said crystalline form being characterised in that said form has an XRPD pattern having only two peaks at 2θ 9.1746±0.2 and 18.1788±0.2 when the crystalline form is dispersed in a DES solvent (DES), an Ionic liquid (IL) and wherein the XRPD is measured using Cu radiation with a Kα2/Kα1 ratio of 0.5.
