| titleOfInvention | Method of obtaining catalysts of water-alkali dehydrochlorination |
| abstract | FIELD: chemistry. n SUBSTANCE: broken production wastes of allyl chlorides, containing 60.1-65.1% mass of the total cis-, trans-1,3-dichloropropene, 20-23% mass of 1,2 dichloropropane, 3÷3.5% mass of 1,2,3- trichloropropane are initially conditioned at a temperature of 5-10°C with diethyl amine, or at a temperature of 50-55°C diethyl amine at the mole ratio 1,3-dichloropropene: secondary amine equals 1.0:1.1 with further processing of the reaction mass stoichiometrical amounts to the secondary amine 25÷35% NaOH solution. Further, the mixture is held for 0.5÷1 hour, cooled and separate the organic phase, containing chlorides of tertiary amines with the formula (CH 3 ) 2 N-CH 2 -CH=CHCl, or (C 2 H 5 ) 2 -CH 2 -CH=CHCl. Then one adds to it a stoichiometric amount to the initial 1,3-dichloropropene haloid dodecane, it is held with the increase of temperature for a period of 3.5÷4.0 hours with subsequent cooling to room temperature with the separation of the desired product constituting of a syrupy consistency of bright yellow colour of the formula where R - methyl, ethyl; Hal chlorine, bromine. n EFFECT: obtaining a high-efficiency catalyst from available raw material. n 9 cl, 1 tbl, 1 dwg |
