Abstract

A multi-phase W-contained catalyst for preparing glutaraldehyde from cyclopentene through selective oxidizing by the aqueous solution of hydrogen peroxide is prepared through synthesizing the meso-porous MCM-48 all-silicon molecular sieve while adding the tungstic acid precursor to introduce the tungsten oxide with high catalytic oxidizing activity to the skeleton of MCM-48 molecular sieve. Its advantage is high selectivity and output rate of glutaraldehyde.

Description

technical field

[0001] The invention belongs to the technical field of chemical industry, and in particular relates to a tungsten-containing mesoporous molecular sieve catalyst used for heterogeneous catalytic oxidation of cyclopentene to synthesize glutaraldehyde and a manufacturing method thereof. Background technique

[0002] Glutaraldehyde is a very important chemical product, which is widely used as a disinfectant, a leather tanning agent, a fixative for optical and electron microscope tissue sections, a cross-linking agent for proteins and polyhydroxy compounds, and a micromicelle curing agent, etc. . At present, because glutaraldehyde is widely used in secondary oil recovery water injection fungicides in oilfields, the demand for glutaraldehyde has risen sharply. It is estimated that the total domestic demand for pure glutaraldehyde will reach 20,000 tons / year. Most of the glutaraldehyde currently used in China is imported, and only a few units such as Wuhan Organic...
