Production Method
1, 1 mol C12 fatty alcohol and 7 mol ethylene oxide condensation after neutralization, decolorization.
2, 1 mol C12 ~ 18 fatty alcohol is condensed with 20 mol ethylene oxide under solid alkali catalysis.
The reaction is carried out in a tubular reactor.
The front part of the reactor is divided into 264 steel pipes with a length of 5.5 m and a diameter of 16mm, and the rear part is divided into 58 steel pipes with a length of 5.5 m and a diameter of 25.4mm.
The tubes are connected in series with U-shaped rings.
Among them, the 16 mm tube has a total length of 1,448mm and the 25.4mm tube has a total length of 318mm.
The front part of the 16 mm tube is the preheating zone, the rest is the reaction zone, and the 25.4mm tube is all the impregnation zone.
All tubes are placed in a sealed sink.
A certain amount of hot water entering the water tank is maintained through the pipe and the controller, and the temperature in the reaction chamber is maintained at 120~140 ℃.
This temperature is controlled by a pressure control regulator.
There are many ethylene oxide feed ports on the cover of one end of the water tank, and the feed port is connected with the ethylene oxide storage tank.
The specific operation is to add the solid catalyst into the feeding tank, pump the melted fatty alcohol into the feeding tank, mix the two raw materials in the feeding tank and then drive into the preheating part of the reaction chamber.
When the temperature rises to 50~70 ℃, ethylene oxide is pressed into each feeding port from the storage tank and enters the reaction chamber.
The cloud point (1% aqueous solution) measured by material extraction reaches about 75 ℃ and the reaction ends.
The reaction solution enters the neutralization kettle, uses glacial acetic acid to adjust the pH value to 5.0~7.0, then adds hydrogen peroxide to bleach and decolorize, and cools to below 50 ℃.
The finished product is finished by discharging and packaging.
