Embodiment 1
[0063] Put the allyl alcohol polyoxypropylene ether with the number average molecular weight of 1000 and α-decene into the reactor at a mass ratio of 5:1, stir and mix, add the initiator benzoyl peroxide (account of allyl alcohol polyoxypropylene 5% of the total mass of ether and α-decene), the temperature was raised to 100° C., and the reaction was carried out for 6 hours to obtain a crude product. Wash the crude product with a 5% sodium bicarbonate solution, then wash it with deionized water to neutrality, and finally dehydrate it under vacuum at 110°C to obtain the allyl alcohol polyoxypropylene ether / Alpha-decene copolymer synthetic lubricant base oil.
[0064] Infrared analysis of samples using Fourier transform infrared spectroscopy, such as figure 1 shown.
[0065] Spectrum analysis is as follows: the main absorption peaks in the spectrum are: 2910, 2850cm -1 The left and right are the stretching vibrations of saturated C-H bonds in methyl and methylene groups; the ...
Embodiment 2
[0068] Put methallyl alcohol polyoxypropylene ether with a number average molecular weight of 800 and α-dodecene in a mass ratio of 8:1 into the reactor, stir and mix, add initiator benzoyl peroxide tert-butyl ester (account for 3% of the total mass of methallyl alcohol polyoxypropylene ether and α-dodecene), the temperature was raised to 90° C., and the reaction was carried out for 5 hours to obtain a crude product. Wash the crude product with 5% sodium bicarbonate solution, then wash it with deionized water until neutral, and finally dehydrate it under vacuum at 110°C to obtain methallyl alcohol polyoxypropylene with the appearance of a colorless transparent oily liquid Ether / alpha-dodecene copolymer synthetic lubricant base oil. The physical and chemical properties are shown in Table 1.
Embodiment 3
[0070] Put the prenol polyoxypropylene ether with the number average molecular weight of 1300 and α-decene into the reactor at a mass ratio of 7:1, stir and mix, add the initiator methyl ethyl ketone peroxide (account of prenyl polyoxypropylene 4% of the total mass of ether and α-decene), the temperature was raised to 110° C., and the reaction was carried out for 7 hours to obtain a crude product. The crude product was washed with 5% sodium bicarbonate solution, then washed with deionized water until neutral, and finally dehydrated under vacuum at 110°C to obtain prenol polyoxypropylene ether with the appearance of a colorless transparent oily liquid / Alpha-decene copolymer synthetic lubricant base oil. The physical and chemical properties are shown in Table 1.
