METHOD FOR PREPARING DOUBLE-SEALED-END GLYCOL ETHER |
摘要 |
Disclosed is a method for preparing a double end capped glycol ether, the method comprising: introducing into a reactor a raw material comprising a glycol monoether and a monohydric alcohol ether, and enabling the raw material to contact and react with an acidic molecular sieve catalyst to generate a double end capped glycol ether, a reaction temperature being 50-300ºC, a reaction pressure being 0.1-15 MPa, a WHSV of the glycol monoether in the raw material being 0.01-15.0 h-1, and a mole ratio of the monohydric alcohol ether to the glycol monoether in the raw material being 1-100:1. The method of the present invention enables a long single-pass lifespan of the catalyst and repeated regeneration, has a high yield and selectivity of a target product, low energy consumption during separation of the product, a high economic value of a by-product, and is flexible in production scale and application. |
