Description
Humic acid, also known as humus acid, is a complex mixture of natural organic polymer compounds. It is a black or black-brown amorphous powder, slightly soluble in water and acid, and soluble in hot concentrated nitric acid with a dark red color. Humic acid contains elements such as carbon, hydrogen, oxygen, nitrogen, and active groups such as hydroxyl, carbonyl, carboxyl, quinone, methoxy, and aromatic nuclei. It exhibits weak acidity, hydrophilicity, complexation, redox, ion-exchange, and physiological activity.
Uses
Used in Agricultural Industry:
Humic acid is used as a fertilizer and soil acid regulating agent for improving the growth and cultivation of crops, citrus, turf, and flowers. It is also used to improve the strength of organically-deficient soils and stimulate the immune system, treating various viral infections.
Used in Drilling Fluid Industry:
Humic acid is used as a filtrate reducer with resistance to high temperature for fresh water drilling fluid, reducing viscosity but with poor salt resistance.
Used in Chemical Research:
Humic acid serves as a raw material for the production of humic acid compound fertilizer, drilling additives, and pesticides. It is also used in biochemical research due to its complex structure and properties.
Used in Plant Growth:
Humic acid acts as a plant growth stimulating hormone, connecting with carboxyl, hydroxyl, carbonyl, benzoquinonyl, methoxy, and other functional groups. It exchanges with metal ions, adsorbs, complexes, chelates, and has effects on condensation, peptisation, and dispersion in a dispersive system.
Used in Environmental Applications:
Humic acid is used as a soil supplement in agriculture and as a human nutritional supplement. It helps plants absorb nutrients effectively through chelation with positively charged multivalent ions.
Used in Industrial Applications:
Humic acid is used in drilling fluids, printing inks, and as a metal chelator and pigment in various industries. Its sodium or ammonium salt can be used to prepare humic acid coalball as a binder.
Drilling fluid
Humic acid is the effective component of the coal alkali solution for the fluid loss additive of slurry. It is not a single compound, but a mixture of a variety of compounds with different molecular sizes and inconsistencies in the structure. These compounds contain nitrogen, hydrogen, oxygen, carbon and other elements. From the analysis of functional groups and structural, it is proved that they are the multifunctional chain polymers containing aromatic rings and alkene bonds. These functional groups contain carboxyl, alcohol hydroxyl, phenolic hydroxyl, methoxy, quinoxy, nitrogen-containing group and so on. Carboxyl, phenolic hydroxyl and methoxy play the leading role in mud treatment agents. Molecular weight from 1900~4900, such as:
How it is originated
It is mainly formed by the ancient plants, which accumulated in marshland after death. Through the complex biochemical and physicochemical changes, the decarboxylation and dehydration reaction had occurred in the plant wreckage, releasing gaseous products such as carbon dioxide, water, and methane. Finally, a new brown gelatinous substance - peat was produced. The peat contains a large amount of humic acid, bitumen and a large amount of water.
Preparation
The reaction of lignite and caustic soda [lignite: caustic soda = 100: (10~20) (mass ratio)]. The product can be obtained after the reaction liquid is filtered, concentrated and dried.
Check Digit Verification of cas no
The CAS Registry Mumber 1415-93-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,1 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1415-93:
(6*1)+(5*4)+(4*1)+(3*5)+(2*9)+(1*3)=66
66 % 10 = 6
So 1415-93-6 is a valid CAS Registry Number.
