Embodiment 1
[0031] Embodiment 1 (1). The synthesis of Jubet alcohol polyoxyethylene ether:
[0032] Add Gubet alcohol and powdery potassium hydroxide to form reaction system in the reactor that condensing unit, stirring device and gas disperser are housed, contain the Gubet alcohol of 0.45 mole and the potassium hydroxide of 0.32 gram powder in the system, Heat to 156°C. Blow the entire reaction system with pure nitrogen for 13 minutes to remove the air in the system, then slowly pass ethylene oxide through the safety device, and enter the Gubet dodecyl alcohol-potassium hydroxide solution in the reactor through the gas disperser In the process, the addition reaction of ethylene oxide and Jubet dodecyl alcohol (absorbing ethylene oxide), the speed of adding ethylene oxide is controlled so that the ethylene oxide gas can be completely absorbed by Jubet dodecyl alcohol prevail. After the reaction is complete (it usually takes about 8 hours for ethylene oxide to be completely absorbed), bl...
Embodiment 2
[0038] Embodiment 2 (1). The synthesis of Jubet alcohol polyoxyethylene ether:
[0039]Add Gubet alcohol and powdery potassium hydroxide to form reaction system in the reactor that condensing unit, stirring device and gas disperser are housed, contain the Gubet alcohol of 0.467 moles and the potassium hydroxide of 0.3 gram powdery in the system, Heat to 155°C and keep the temperature constant at 155±2°C. Blow the entire reaction system with pure nitrogen for 15 minutes to remove the air in the system, and then slowly pass ethylene oxide through the safety device, and then add it to the Gubet tetradecyl alcohol-potassium hydroxide in the reactor through a gas disperser. In the solution, carry out the addition reaction (absorbing oxyethane) of oxyethane and Jubet tetradecyl alcohol, the speed of adding oxyethane is controlled in oxyethane gas and can pass through Jubet tetradecyl alcohol completely Absorption prevails. After the reaction is complete (it usually takes about 6 h...
Embodiment 3
[0046] Embodiment 3 (1). The synthesis of Jubet alcohol polyoxyethylene ether:
[0047] Add Gubet alcohol and powdery potassium hydroxide to form reaction system in the reactor that condensing unit, stirring device and gas disperser are housed, contain the Gubet alcohol of 0.47 mole and the potassium hydroxide of 0.38 gram powder in the system, Heat to 150°C. Blow the entire reaction system with pure nitrogen for 12 minutes to remove the air in the system, then slowly pass ethylene oxide through the safety device, and enter the Gubet cetyl alcohol-potassium hydroxide solution in the reactor through the gas disperser In the process, the addition reaction of ethylene oxide and Jubet cetyl alcohol (absorbing ethylene oxide), the speed of adding ethylene oxide is controlled so that the ethylene oxide gas can be completely absorbed by Gubet cetyl alcohol prevail. After the reaction is complete (it usually takes about 7 hours for ethylene oxide to be completely absorbed), blow the...
