preparation example Construction
[0043] The present invention provides a kind of preparation method of paraffin ether described in above-mentioned technical scheme, comprising:
[0044] Reaction of halogenated paraffin and sodium alkoxide to obtain paraffin ether;
[0045] The molecular formula of the halogenated paraffin is formula II:
[0046] C n h m1 x m2 Formula II,
[0047] In formula II, m1+m2=2n+2,
[0048] X is a halogen,
[0049] n is 10-30,
[0050] The number of carbon atoms of sodium alkoxide is 1-10.
[0051] In the present invention, the values of m2 and n are consistent with the values of m2 and n in formula I, and will not be repeated here; the X is preferably Cl or Br. In the present invention, the molecular formula of the halogenated paraffin is preferably C 25 h 45 Cl 7 or C 15 h 26 Cl 6 . The present invention has no special limitation on the type and source of the halogenated paraffin, and the halogenated paraffin well-known to those skilled in the art can be used, pr...
Embodiment 1
[0080] Add chlorinated paraffin 42 and sodium methoxide with a molar ratio of 1:7 into a reaction kettle equipped with stirring, condensing and heating devices, stir and mix evenly, react at 40°C and 200rpm for 4h, cool down to room temperature, and obtain Crude solution of paraffin-42;
[0081] Place the crude solution of paraffin methyl ether-42 and n-hexane extractant with a volume ratio of 1:3 in a centrifuge, and centrifuge at a speed of 2000rpm for 3min to obtain an organic phase whose upper layer is paraffin methyl ether-42-n-hexane; The organic phase was distilled under reduced pressure at 50°C and 0.09MPa to separate the n-hexane extractant, and the remaining liquid was paraffin methyl ether-42.
[0082] The paraffin methyl ether-42 prepared in Example 1 of the present invention is carried out infrared spectrum detection, and detection result is as follows figure 1 as shown, figure 1 For the infrared spectrogram of the paraffin ether prepared in Example 1 of the pre...
Embodiment 2
[0084] Add chlorinated paraffin 42 and sodium ethoxide with a molar ratio of 1:8 into a reaction kettle equipped with stirring, condensing and heating devices, stir and mix evenly, react at 75°C and 350rpm for 15h, cool down to room temperature, and obtain Crude solution of paraffin ether-42;
[0085] Place the crude solution of paraffin ether-42 and cyclohexane extractant with a volume ratio of 1:5 in a centrifuge, and centrifuge at a speed of 3000rpm for 5min to obtain an organic phase whose upper layer is paraffin ether-42-cyclohexane; The organic phase was distilled under reduced pressure at 80°C and 0.04MPa to separate the cyclohexane extractant, and the remaining liquid was paraffin ether-42.
[0086] The paraffin ether-42 prepared in Example 2 of the present invention is carried out infrared spectrum detection, and the detection result is as follows: figure 2 as shown, figure 2 The infrared spectrogram of the paraffin ether prepared for Example 2 of the present inve...
