A process for the preparation of functional aliphatic hydrocarbons from volatile liquid hydrocarbons

The invention provides a process for the preparation of functional aliphatic hydrocarbons from volatile liquid hydrocarbons using activated carbon and metal impregnated activated carbon under oxic atmosphere at a temperature not exceeding 400oC. The formation of the simpler hydrocarbons ensures a significant decrease in emission of total carbon-di-oxide in the atmosphere, thereby providing a solution to reduce global warming problem. Moreover,  the hydrocarbons, produced by the process of the invention, find several industrial applications. The main feature of the process is that the process enables 100 % conversion of the hydrocarbon.

The most important application of the process of the present invention is envisaged to be in processing industries for the purpose of minimizing the pollution load by converting toxic aromatic hydrocarbons into simpler aliphatic hydrocarbons. For example, leather processing industry, which is associated with environmental pollution due to the emission of volatile   hydrocarbons, is envisaged to be a potential user of the process. Besides, the process finds several other industrial applications.  It has enormous potential applications as catalytic converters in automobile industry to minimize exhaust emissions. It may also find application in the energy sectors as an important sustainable source of hydrogen, required  for fuel cells in mobile and stationery applications. Moreover, the process is envisaged to have application in petroleum industries for the purpose of oxidation of liquid hydrocarbons in refinery streams. Further, the process may find application in chemical industries for the synthesis of fine chemicals from bulky organic substances.
The invention has been applied for patent protection (Indian Patent application no. 709Del2008; Patent pending).


A process for the preparation of polyacrylate dispersion having free monomer content less than 0.1% v/v.

The resulting polyacrylate dispersion exhibits free monomer content less than 0.1%v/v. The product finds potential application in pharmaceutical industry for sustained release of drugs.
The process has been applied for Patent protection (Indian Patent application no. 209DEL2001; Patent pending). The technology has already been transferred to industry.

A process for the preparation of acrylate -amino acid nanoparticle copolymer dispersion for industrial applications.

The present invention relates to a process for the preparation of acrylate -amino acidcopolymer in the form of aqueous dispersion having particle size as low as 40nm. Polymerisable amino acid is copolymerised with water insoluble acrylate monomer, taken in the form of aqueous dispersion, under controlled conditions to prepare nanoparticle dispersion, which is facilitated by the typical interfacial coverage afforded from selected amino acid. The unique feature of the process is that the process involves comonomer from amino acid/peptide derivative which is biodegradable.
 The resulting dispersion finds enormous industrial applications in leather processing industry as retanning agents for imparting fiber compaction, improved softness and fullness buffing property. The copolymer may also find application in textile industry.
The invention has been applied for patent protection (Indian patent application no. 388Del2006; Patent pending).

A novel ketene oligomer from aliphatic nonpolar  amino acids and a process for the preparation thereof

This invention essentially relates to a novel ketene oligomer of the general formula [R1R2C=C=O]n, where ‘n’ is an integer in the range of 10 to 16; R1 and R2 are hydrogen atoms or alkyl groups having carbon chain length in the range of 1 to 4; R1=R2 or R1≠R2.
More particularly, the invention relates to linear ketene oligomers of molecular weight in the range of  500 – 1000 having polyketene structure. The invention further provides a process for the preparation of the novel ketene oligomer from aliphatic non-polar amino acids in presence of transition metal impregnated activated carbon as catalyst.
The oligomer of the invention finds enormous application in providing eco-friendly solutions in respect of a range of environmental pollution problems, because it acts as a strong chelator for transition metals to produce an effective reusable complex for inactivating wide spectrum of anaerobes and aerobes in the environment.
The invention has been applied for Patent protection (Indian Patent application no. 0393DEL2007).
