Figure 3.1 Synthesis pathway of N-alkyl formamides The synthesis procedure was quite straightforward in which equimolar quantity of amine was mixed with formic acid and heated to 140 oC to evolve the reaction water. The products so obtained were pure enough as inferred from 1H-NMR and FTIR spectra. It is important to note that both NMR and FTIR spectra of the formamides show very similar patterns, for instance the hexyl formamide derived from hexyl amine and formic acid exhibits a strong carbonyl vibration at 1650 cm-1 and a N-H plane bending band at 1530 cm-1 in the FTIR spectrum. The other peaks, N-H stretching vibration at 3350 cm-1 and C-N vibration bands at 1220 and 1100 cm-1 support the proposed formamide structure. 1H-NMR spectrum of this product shows a weak signal of formamide proton at 8.0 ppm. The broad signal centered at 5.3 ppm must be associated with N-H proton. The proton signals of methylene group linked to nitrogen appears as downfield signal at 3.3 ppm, while the remaining protons of aliphatic carbons lie in between 0.9-1.6 ppm range. The residual hexyl amine in the crude product shows proton signals at 3.2 ppm as a weak triplet. The products except dihexyl formamide were liquid at room temperature. Dihexyl formamide is a low melting solid that melting slightly above room temperature (35- 40 oC). The FTIR and 1H-NMR spectra were described in detail as listed below. Hexyl formamide (distilled product): Boiling point (120 oC/12 mm Hg). 1H –NMR, δ 8 (1H, s, OC-H), 5.3 (1H, b, N-H), 3.3 (2H, t, N-CH2), 1.2-1.6 (8H, m, CH2 of the linear chain), 0.9 (3H, t, CH3 end group). Significant FTIR peaks: sharp peak at 1640 cm-1 (C=O stretching vibration), the strong band at 1530 cm-1 (N-H plane bending 40PDF Image | SEPARATION OF LITHIUM FROM BRINES

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.
