BACK GROUND AND PRIOR ART OF THE INVENTION
It is also known that lignite is referred to as brown coal is the lowest rank of coal and used almost exclusively as fuel for steam electric generation. Although there are
15 attempts to produce value added products for other utilities, the major consumption
of the lignite is aimed mainly for power generation. Lignite, which is rich in carbon is the result of decomposition of vegetation over a millions of years ago which underwent compaction and heating. Because of its vegetative origin, this material is very rich in various functionally efficient organic molecules and it will be more
20 beneficial to use these functionally efficient organic molecules present in lignite.
These functionally efficient organic molecules are functionally efficient than normal organic molecules (humic, fulvic acids etc.) present in lignite or leonardite due to enhanced reactive nature obtained by treating with hydrogen peroxide or alkaline hydrogen peroxide which are resultant of cleavage of lignite. Lignite composition
25 variability prohibits utilization of hydrogen peroxide at higher concentration which
results in burning of lignite resulting in failure of obtaining cleaved organic molecules from lignite. Present invention has its application to solve this problem.
This invention has its application in development of sequential cleavage of lignite with hydrogen peroxide to obtain functionally effective organic molecules.

The embodiment of the invention is to provide method of producing functionally effective organic molecules by sequential cleavage of lignite with hydrogen peroxide.
The salient feature of this invention is described below with following examples for preparation of functionally effective organic molecules by sequential cleavage of lignite with hydrogen peroxide.
Example 1
10-50% hydrogen peroxide was added to micronized lignite in a ratio of 1 : 1 - 1: 10 (v/w) based on lignite quality. After this reaction the same step was repeated twice or thrice or more times depending up on the yield requirement of cleaved product based on type of lignite. Further 50% hydrogen peroxide was added directly to the same based on the requirement and obtaining the resultant material, which can be used with or without extraction of cleaved product. For extraction of cleaved products from the treated lignite, solvent such as water was used with or without heating. At 10°C the same quality lignite is reacted with 25 %H202 and temperature
of the reaction was gradually enhanced to 16 to 20 C, allowing the reaction of H202 gradually with temperature control without burning the lignite. The reaction conditions are varied with lignite quality derived from different parts of globe (China, Australia, US, Europe,).
Example 2
Alkaline hydrogen peroxide (containing alkali, NaOH or KOH (1-10%) with hydrogen peroxide (0.2 - 20%) was added to lignite at ratio of 1 :2 - 1 : 10 depending on lignite quality. The same step was repeated twice or thrice or more times depending on the lignite quality and based on the required yield of the cleaved product.
Example 3
The organic molecules obtained by lignite cleavage were structurally modulated with absorption of nitrogen gas under high pressure of 10kg/cm2. These organic molecules were mixed or blended with various solvents and solutions to suit various purposes such as mixing of ethanol or methanol with these organic molecules for plant nutrition through foliar spray.
There are several ways to supply above organic molecules obtained by lignite cleavage to crops: by soil application, fertigation, foliar spray, seed treatment, or combination with crop protection products. Each option has specific advantages and disadvantages depending on the nutrient, the crop and the soil characteristics. Similarly, the different product types (e.g. chelated/non-chelated, organic/inorganic, granular/fluid) have respective relative strengths. The various options have quite different impacts on the solubility and availability of the micronutrients, on the uniformity of application, as well as on health, safety and the environment.
The organic molecules obtained by lignite cleavage according to the present invention are either low molecular weight (LMW) or high molecular weight (HMW) and capable to use with phosphate fertilizers, urea fertilizers, micronutrient fertilizers or kimberlite based fertilizers.
The organic molecules obtained by lignite cleavage according to the present invention are generally applied to the plant or part thereof, with an agriculturally acceptable carrier. By the term "agriculturally acceptable carrier" is meant a substance which may be used to dissolve, disperse or diffuse an active compound in the composition without impairing the effectiveness of the compound and which by itself has no detrimental
effect on the soil, equipment, crops or agronomic environment. The organic molecules obtained by lignite cleavage according to the present invention may be either solid or liquid formulations or solutions. For example, the compounds may be formulated as wettable powders, or a concentrate which is emulsifiable. It is often desirable to include adjuvant, such as wetting agents, spreading agents, dispersing agents, stickers and adhesives, in accordance with conventional agricultural practices.
For the preparation of emulsifiable concentrates, one or more of the active ingredients may be dissolved in one or more organic solvents, such as benzene, toluene, xylene, methylated naphthalene, corn oil, pine oil, o-dichlorobenzene, isophorone, cyclohexane and methyl oleate, or mixtures thereof, together with an emulsifying agent which permits dispersion in water.
