Embodiment 1
[0031] Add 1 mol of lauryl alcohol, 1.5 mol of ethyl chloride and 1.1 mol of sodium hydroxide into a reaction kettle with a stirring, condensing and heating device, stir and mix evenly, react at 120°C and 200 rpm for 24 hours, and cool down to room temperature to obtain lauryl alcohol Crude ether.
[0032] Adjust the pH of the above crude lauryl ether to 7 with hydrochloric acid to obtain a dark yellow mixed solution; centrifuge the dark yellow mixed solution, control the centrifuge speed at 900r / min, and centrifuge for 5 minutes to remove solid salts to obtain a yellow liquid mixture The yellow liquid mixture was subjected to vacuum distillation, the vacuum degree of the vacuum distillation was controlled to be 0.04MPa, the vacuum distillation temperature was 80°C, and the unreacted raw materials were recovered to obtain pure light yellow lauryl ether.
[0033] The pure lauryl ether obtained after purification in Example 1 of the present invention was detected by infrared spe...
Embodiment 2
[0035] Add 1 mol of lauryl alcohol, 1.5 mol of chloropropane and 1.1 mol of sodium hydroxide into a reaction kettle with a stirring, condensing and heating device, stir and mix evenly, react at 120°C and 200 rpm for 24 hours, and cool down to room temperature to obtain lauryl alcohol Crude propyl ether.
[0036] Adjust the pH of the above crude propyl ether to 7 with oxalic acid to obtain a dark yellow mixed solution; centrifuge the dark yellow mixed solution, control the speed of the centrifuge to 1400r / min, and centrifuge for 2 minutes to remove solid salts to obtain a yellow liquid The mixture: the yellow liquid mixture was subjected to vacuum distillation, the vacuum degree of the vacuum distillation was controlled to be 0.09 MPa, the vacuum distillation temperature was 90° C., and the unreacted raw materials were recovered to obtain a light yellow pure product of propyl lauryl ether.
[0037] The pure product of propyl lauryl ether obtained after purification in Example 2...
Embodiment 3
[0039] Add 1 mol of lauryl alcohol, 1.5 mol of chlorobutane and 1.1 mol of sodium hydroxide into a reaction kettle with a stirring, condensing and heating device, stir and mix evenly, react at 120°C and 200 rpm for 24 hours, and cool down to room temperature to obtain laurel Alcohol butyl ether crude.
[0040] Adjust the pH of the above crude butyl alcohol butyl ether to 7 with sulfuric acid to obtain a dark yellow mixed solution; centrifuge the dark yellow mixed solution, control the speed of the centrifuge to 1100r / min, and centrifuge for 3 minutes to remove solid salts to obtain a yellow liquid The mixture: the yellow liquid mixture is subjected to vacuum distillation, the vacuum degree of the vacuum distillation is controlled to be 0.06 MPa, the vacuum distillation temperature is 100° C., unreacted raw materials are recovered, and light yellow pure butyl lauryl ether is obtained.
[0041] Carry out infrared spectrum, hydrogen nuclear magnetic resonance spectrum and carbon ...
