Technical field
1,3-PD body is prepared the present invention relates to a kind of preparation method of catalyst more particularly in glycerine liquid phase hydrogenolysis
The application of system
Background technology
1,3-PD is a kind of important industrial chemicals, is one of six big petrochemical industry new products generally acknowledged in the world at present,
Available for synthesis cosmetics, brake fluid and the excellent new type polyester fiber (PTT) of ink, particularly manufacturing property is printed, is
" omnipotent raw material ".Therefore in following one period 1, the great market prospects of 3-PDO, synthetic method and application study are at home and abroad
It is highly valued.
The Degussa companies of Germany, the Shell companies in the U.S. and E.I.Du Pont Company have monopolized the market of 1,3-PD, state
Interior 1,3-PDO yield is considerably less, and 1, the 3-PDO in China relies primarily on foreign import.At least 300,000 tons/year of 2005 Nian Qi China
The market demand, and the demand of 1,3-PDO will increase substantially.Relation between supply and demand will further deteriorate, and lead to 1,3-PDO
Price always in 50,000/t or so, hinder 1,3-PDO as staple commodities.The 1,3-PDO synthetic routes tool of developing low-cost
There is very important meaning.
Glycerine is the Main By product of oil prodution industry, and in addition the popularization of biodiesel technology is largely cheap by by-product
Glycerine becomes the desirable feedstock of production 1,3-PDO.At present, the industrialized preparing process of 1,3-PDO has chemistry
Synthetic method and microbe fermentation method.However, admittedly be, above-mentioned production 1, the method pattern disadvantage of 3-PDO is closed with chemistry
The production technology for 1, the 3-PDO that Cheng Fawei is represented still will fundamentally rely on the petroleum industry of unsustainable development, biology hair
Ferment method will be often carried out in two steps, and reaction is made slow progress, and the concentration of products obtained therefrom is low.
