METHOD FOR PREPARING DOUBLE-SEALED-END GLYCOL ETHER

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 50-300° C., 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.

Preparation method for double-terminated glycol ether

The invention relates to a preparation method for double-terminated glycol ether. The preparation method comprises a step of introducing raw materials containing glycol monoether and monohydric ether alcohol into a reactor for contact and reaction with an acidic molecular sieve catalyst so as to produce double-terminated glycol ether, wherein reaction temperature is 50 to 300 DEG C, reaction pressure is 0.1 to 15 MPa, the mass space velocity of the glycol monoether in the raw materials is 0.01 to 15.0/h, and a mol ratio of monohydric ether alcohol to glycol monoether in the raw materials is 1-100: 1. The preparation method has the advantages that the catalyst has long single-pass life and can be repeatedly regenerated; the target product, i.e., double-terminated glycol ether has high yield and selectivity; energy consumption in separation of products is low; by-products have high economic value; production scale can be large or small; and application of the method is flexible.

DIISOPROPOXY- AND DI-tert-BUTOXYETHYNE STABLE ACETYLENE DIETHERS

The rather stable acetylene diethers diisopropoxy- and di-t-butoxyethyne are prepared either from glyoxal or dioxane.Catalytic hydrogenation, acid-catalyzed hydration and formation of the corresponding hexacarbonyl dicobalt complexes are reported.
