| Overview | There are many existing methods for the preparation of chlorinated alkanes such as N-chloropropane, hydrochloric acid and alcohol can be used as raw materials for the preparation of chlorinated alkanes, or chlorine gas and hydrocarbon reaction for the preparation of chlorinated alkanes, can also be used in other methods of addition or substitution. Regardless of the method described above, a chlorine source must be involved in the reaction. With the continuous expansion of the scale of Soda Ash by combined soda process in China, the market problem of ammonium chloride as a by-product has become increasingly prominent, and the development and utilization of ammonium chloride has become a hot issue in our soda ash industry. Ammonium chloride utilization of many ideas, most of the use of ammonia recovery methods, the chlorine into hydrogen chloride, chlorine and other chlorine products. The preparation of chlorinated alkanes by the reaction of alcohol and ammonium chloride is a major research direction. |
| preparation | the preparation of N-chloropropane is as follows: 1) mix zinc chloride and ammonium chloride in a molar ratio of 1: 1, heating and melting, the temperature is controlled at 340 deg C, the steam into propanol reaction with the melt, get a mixture of monochloropropane and water. After condensation, the product of n-chloropropane can be obtained by separation and purification. By gas chromatography analysis, the purity of N-chloropropane can reach 97%. 2) the molten solution after the reaction of zinc chloride, ammonium chloride and propanol contains the ammonia generated by the reaction. After the addition of ammonium chloride, the temperature is raised to 400 ° C., the ammonia is distilled off, and then the reaction is carried out by returning to the cycle of step 1). |
| uses | in organic synthesis, production of pesticides, pharmaceuticals, etc. used in organic synthesis, pesticides, pharmaceutical intermediates |
| production method | is obtained by reacting N-propanol with hydrochloric acid. Anhydrous Zinc chloride was dissolved in hydrochloric acid and N-propanol was added slowly with stirring. After the addition was completed, the reaction was refluxed, and the generated chloropropane was distilled off to 115-120 ° C. To distill off all the chloropropane. The distilled crude product is washed with industrial sulfuric acid, washed with water, washed with 10% sodium carbonate, washed with water, dried with calcium chloride, and fractionated to collect the 44.6-47.5 ° C. Fraction to obtain the finished product. In addition, n-propanol can also be reacted with phosphorus pentachloride to produce chloropropane. |
