N,N,N',N'-Тетракис(2-гидроксипропил)этилендиамин химические свойства, назначение, производство
Описание
N,N,N',N'-Tetrakis(2-hydroxypropyl)ethylenediamine (also known as Quadrol) is a monomer based on ethylenediamine used in the production of polyurethane coatings, adhesives, cosmetics and personal care products. It acts as a chelating agent due to the presence of four hydroxyl groups and as a cross-linking agent due to its two amino groups. It is widely used as a component of polymers and copolymers, especially those designed for UV crosslinked polyurethane polymers, dendritic aminopolymers, conductive polymers, inks and coatings. In addition, Quadrol is also used to produce resins, as well as in the manufacture of surfactants, plasticisers and other chemical products.
Химические свойства
A clear colorless to pale yellow viscous liquid. N,N,N',N'-Tetrakis(2-hydroxypropyl)ethylenediamine(Tetrahydroxypropyl ethylenediamine) is a chelating agent that binds with metal ions or metallic compounds, preventing them from adhering to a surface (such as skin, hair, or clothing) or causing contamination, such as in the case of trace amounts of iron.
Использование
N,N,N',N'-Tetrakis(2-hydroxypropyl)ethylenediamine can be used as cross-linking agent and catalyst in the manufacture of urethan foams; in epoxy resin curing; as complexing agent, humectant, emulsifier, plasticizer.
Имя бренда
Neutrol TE (BASF);
Quadrol (BASF).
Синтез
N,N,N',N'-Tetrakis(2-hydroxypropyl)ethylenediamine can be prepared by the ring-opening addition reaction of ethylenediamine and propylene oxide under the action of a catalyst.
в пробирке
Results show that viability of macrophages incubated with Quadrol (N,N,N',N'-Tetrakis(2-hydroxypropyl)ethylenediamine) at concentrations of 0.5 mM, 1 mM and 4mM are identical to that for controls. Viability, however, is reduced to 50% of control at concentrations of 16 mM to 32 mM. After four hours, at concentrations of 1 mM and 4 mM, Quadrol produces enhanced spreading of 88% and 80%, respectively, as compared to the control of 28%. Quadrol, at a concentration of 16 mM, shows reduced percentage of spreading of macrophages after four hours. Exposure of macrophages to 1.0 mM or 4.0 mM Quadrol concentrations enhances phagocytic activity, 41% and 57%, respectively, over that of the cells exposed to media alone (34%).
