Application of tripotassium EDTA
Latest company news about Application of tripotassium EDTA

The full name of ethylenediaminetetraacetic acid tripotassium tripotassium ethylenediaminetetraacetic acid tripotassium, English abbreviation: EDTA K3, is a white crystalline powder, which is colorless, odorless, easily soluble in water, and very easy to absorb moisture. Although it looks unremarkable, it is an application and a wide range of chemical raw materials. Today we will analyze the application and characteristics of tripotassium EDTA in various aspects.

EDTA K3 test report

 

1. It is used in the preparation of Anticoagulant For Blood Collection in medical tests, purple anticoagulation tubes, vacuum anticoagulation tubes, and a whole blood analyzer. It is especially suitable for blood tests in various clinical emergency departments, and is also an important additive in blood collection tubes. As a EDTA salt in the industry, Hubei Xindesheng Material Technology Co., Ltd. can protect the blood cell components, does not affect the white blood cell count and size, has minimal impact on the morphology of red blood cells, and can inhibit platelet aggregation, suitable for general hematology tests. Except for the separation test of platelets, it is not suitable for coagulation test and platelet kinetic energy test, nor for calcium ion, potassium ion, sodium ion, iron ion, alkaline phosphatase, creatine kinase and leucine aminopeptidase Determination and PCR experiments.

 

2.Used in detergents, liquid soaps, shampoos, agrochemical sprays, antidotes. Ethylenediaminetetraacetic acid in EDTA K3 is an amino polyacid. Because it can form a chelate with most metal ions, it becomes a general-purpose strong chelating agent. Due to this property, it can be combined with deionized water, solid alkali, and linear alkylbenzene sulfonic acid, surfactants and some auxiliary agents to form a detergent, and this formula is non-toxic to the skin. Harmful, non-irritating. And as a detergent, it can exert its chelating effect, mainly chelating with calcium and magnesium ions, so that the water is softened and easy to clean.

 

3. A self-cleaning high-borosilicate glass rod is prepared. It can be first mixed with deionized water, 34-44 parts of aluminum isopropoxide, etc. and heated to 40-45°C to form a colloidal liquid, and then reacted with tetrabutyl titanate, 11-15% ammonia water, ethanol to generate After the colloidal liquid is mixed and stirred evenly, a self-cleaning coating is made. After the surface of the high borosilicate glass rod is cleaned, it is placed in this self-cleaning coating for 10-14 minutes, then taken out and placed in a high-temperature furnace. After sintering, the finished high-borosilicate glass rod with self-cleaning function can be prepared. In the preparation process, the tripotassium salt of ethylenediaminetetraacetic acid is used as an important additive in the colloidal liquid, which can effectively improve the adhesion performance of the prepared colloidal liquid, improve the uniformity of the dispersion of the AlOOH colloid, and prevent its precipitation. The phenomenon becomes an important colloidal dispersant.

 

4. A heat insulation coating for building exterior wall is prepared. In terms of parts by weight, including pure propylene emulsion 80-120 parts, Ta2O5-ZnO-SnO2 composite oxide powder 20-30 parts, ethylenediaminetetraacetic acid tripotassium 5-10 parts, kaolin 2-5 parts, borax 1-5 Parts, antifreeze 2 to 5 parts, film-forming aid 5 to 10 parts, pyrophosphate 1.5 to 2.3 parts, thickener 1 to 2 parts, polyoxyethylene polyoxypropylene pentaerythritol ether 2 to 3 parts and o-nitro Benzenesulfonic acid 0.5 to 1 part, water 100 to 150 parts. Through the test, it was found that the introduction of tripotassium ethylenediaminetetraacetic acid in the exterior wall paint can significantly improve the acid corrosion resistance of the paint, so that in cities with severe acid rain, the above paint can also ensure a good service life and is not easy to corrode.

 

5. Preparation of dyes. SDS, bromophenol blue, EDTA K3, sucrose, etc. can be used to make a 2.5-fold concentrated protein loading buffer. Take an appropriate amount of protein sample and dye mixture, mix well, and then directly load the sample into the relevant gel sample hole to perform relevant detection and operation.
