| Application | n-Decane is the main raw material for the production of fourteen carbon alkanes, and other applications include liquid mosquito coil, hydraulic oil of large-scale Press, chlorinated paraffin, anti-corrosion coating, powder coating can also be used as high-grade Hot Melt Adhesive, its derivative products tetradecanedioic acid linear polyanhydride, is a very useful chemical pharmaceutical intermediates, can be used for epoxy and propylene resin curing agent, polyester modified additives and so on. Is the main raw material of nylon 1214 can also be used as military equipment, mechanical parts, automobile pipe, edge cold chain, etc. |
| preparation | (1). N-heptane 1790 was substituted. 8g(10mol) with n-decane bromide 2211. 8g(10mol) are mixed uniformly to form a mixed solution of bromoalkane, which is ready for use;(2). Weigh 483g(21mol) of sodium metal and cut it into small thin strips with an area of approximately 1 x 3 cm2 for use;(3). Put 50g of bromoalkane mixture and 20g of sodium metal in the reaction kettle, stir and raise the temperature to 80°C, remove the heat source, rely on the reaction heating, and maintain it at 120°C, and continuously add the remaining bromoalkane mixture dropwise, metal sodium is added to maintain a slightly reflux state, and the feeding is completed, and the temperature is controlled at 160 ° C. And the temperature is constant for 2 hours;(4). 400g of 95% ethanol and 260 ml of water were added sequentially to separate the organic matter, washed with water until neutral, dried over anhydrous magnesium sulfate, and then distilled to collect a fraction at 280-°C, the fraction was washed with 600g of concentrated sulfuric acid to a pale yellow acid layer, washed with water to neutral organic phase, dried, and collected through a fractionation column 500g 96% N-decane, 600g 98% N-decane, 500g 97% Of N-eicosane, the obtained N-alkane content is 96% to 98%. |
