Figure A.9 H-NMR spectrum of 4 octyl 12-crown-4 ether Figure A.9 shows that the peak which is divided into three at 0.9 ppm represents methyl groups at the end of four octyl groups. The signals around 1.3 and 1.5 show the methylene bridge protons near to oxygen. In signal at 3.5 ppm, -CH2- groups on the ring are detected. They are shifted to right which may be caused by the lithium ions coordinated in the middle of the ether ring. The synthesis of 4 octyl 12-crown-4 ether started with dissolving lithium chloride in minimum amount of N-methyl pyrrolidone. Then, 1,2 epoxy octane was added into the mixture. The molar ratio of lithium chloride to 1,2 epoxy octane was 1:4. The mixture was then heated to 140 oC and 2 ml of triethyl amine was added to the mixture. Under a reflux, the reaction continued for 12 hours. The resulting black mixture was mixed with water and boiled to recover the desired product with water. After 10 hours of distillation, the water and slightly yellow colored organic material were condensed and mixed with diethyl ether to extract the organic material from water. The ether phase was separated by a separation funnel and remaining solvent was evaporated in rotary evaporator which left the desired product. The resulting product was very low in quantity, so the 157PDF 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.CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com (Standard Web Page)
