Product Applications

1. MOA-3, MOA-4, MOA-5 are easily soluble in oil and polar solvent. Water is diffused and has good emulsifying properties. It is used as w/o emulsifier, it is used for emulsification of mineral oil and aliphatic solvent, and the viscosity reducing agent of igelite Sol. It is widely used in chemical fiber oil. Moa-3 is produced..

Production method

1.1 mol C12 ~ 18 fatty alcohol condenses with 20 mol ethylene oxide under solid base catalysis. The reaction is carried out in a tubular reactor. The front part of the reactor is divided into 264 5.5 m long and 16mm diameter steel pipes, and the rear part is divided into 58 5.5 m long and 25.4mm steel pipes. The tubes are connected in series by U-bent. The total length of 16mm tube is 1 448mm, and the total length of 25.4mm tube is 318mm. The front of the 16mm tube is the preheating zone, the rest is the reaction zone, and the 25.4mm tube is all the dipping zone. All tubes are placed in a sealed sink. A certain amount of hot water entering the water tank is maintained through pipes and controllers, and the temperature in the reaction chamber is maintained at 120 ~ 140℃. This temperature is controlled by the pressure control regulator. There are many ethylene oxide feeding ports on the cover of one end of the sink, and the feeding ports are connected to the ethylene oxide storage tank.

The specific operation is to add the solid catalyst into the feeding tank, the molten fatty alcohol is pumped into the feeding tank, and the two kinds of raw materials are mixed in the feeding tank and then transferred into the preheating part of the reaction chamber. When the temperature rises to 50 ~ 70℃, ethylene oxide presses into each feeding port from the storage tank and enters the reaction chamber. The reaction was terminated when the turbidity point (1% aqueous solution) reached about 75℃ after material extraction. The reaction solution enters the neutralization kettle, adjusts the pH value to 5.0~7.0 with glacial acetic acid, then adds hydrogen peroxide to bleach and decolorize, and cools to below 50℃, and the discharge package is the finished product.
