Descripción del producto
Dipotassium ethylenediaminetetraacetate (EDTA*2K), its CAS number:
********7; appearance is white powder; molecular formula:
C*0H*4K2N2O8·2H2O.
Application of dipotassium ethylenediaminetetraacetate:
1. Additives for vacuum blood collection tubes: EDTA*2K can chelate
with calcium ions in the blood to prevent blood coagulation, and
has a fast dissolution rate and good anticoagulation effect. When
using, pay attention: because the blood collection tube is valid
for two years, when the use environment changes slightly, such as
temperature changes, water can easily evaporate to the tube wall
(especially the water in the plastic PET tube solvent can penetrate
the tube wall Leakage), causing the EDTA*2K in the tube to
crystallize quickly. The crystallized EDTA*2K blood collection tube
must be turned upside down at least 8 times when collecting blood,
so that the crystallized EDTA*2K can be fully dissolved and mixed
in the blood. , If the action is a little bigger, the red blood
cells will be destroyed and hemolyzed, and the platelets will
aggregate and adhere and be broken.
2. Making deodorant: in parts by mass, including the following
substances: acid salt, ammonia, urotropine, dipotassium edetate,
isobutanolamine and water.
3. Used as a complexing agent in liquid phase analysis: For
example, a tetrabutylammonium hydrogen sulfate buffer salt system
for liquid chromatography detection, the solvent is water, the
solute includes tetrabutylammonium hydrogensulfate and buffer ion
pairs, the buffer ion pair Composed of potassium dihydrogen
phosphate and phosphoric acid, the solute also includes a
complexing agent, which is preferably EDTA*2K.
4. Preparation of metal polishing agent. The main components of the
polishing agent are: dipotassium ethylenediaminetetraacetate,
trisodium phosphate, dibutyl phthalate, sodium silicate, inorganic
acid, dicarboxylic acid compound, tetrapolyricinoleate, biological
buffer Agents, stabilizers, water-soluble surfactants and water.
The polishing agent thus prepared can effectively remove impurities
and the like on the metal surface.
